Rusty's not very quiet cuda progress

Had brunch with the boys & they asked what I wanted for Christmas, was gonna say cash for the man that has everything & then the bumper popped into my head, sooooooo they said you get it & we will pay!
Anywhoo I will order soon!
Hmmm should I have gone for both???????????
 
I may be trying to make this simpler, but it looks like if you just remove the pin & leave the contacts closed you have a permanent bypass.
That would be great if I had the first-design switch, but I don't. None of the later switches used that arrangement. There is no heater/bimetallic element in the switch I have; it's definitely electromagnetic. If the terminals on mine were wired the way they're shown in the service manual, pushing the button would connect the starter relay to 12V+ key-on (run) position, which would immediately start cranking the engine without twisting the key to start. It would only crank while the button was pushed. The other yellow wire that comes from the interlock module, would then be grounded through the elecromagnet's coil, which makes zero sense since the entire rest of the circuit is positive.

On my switch, it is not possible for the two yellow wires, connected as shown in the service manual (and on your car), to connect to each other. The terminals have no provision to connect. Hence the reason I said this:

...there were two changes to that switch (three separate part numbers in the catalog). Eventually Chrysler supserseded all of 'em to the C-body part, which also has the offset pin. There's a hand-scribbled note in my '74 parts book with a bracket around the earlier-design switches, with the part number "4106798" written. Searching that number shows it's some kind of wiring. My guess is that when they superseded the relay, the connector had to be changed.
That guess is based on what I've found about superseded parts since none of them will plug into your harness (nor any other harness with the connector shown in the manual). Because the interlock switch was still in place on my car, I would expect that car has the updated harness/connector(s). The switch from said car is the only one either of us has, so that's the one we need to make work. The only override switches I could find for sale online were the superseded numbers. Those will not plug into your wiring due to having the offset pin. I assume that means its internal circuits are the same as mine, which as stated above, don't make sense with the factory wiring diagram.

It's entirely possible that just shorting the yellow wires together will work. I said that seemed the obvious solution from the get-go several posts ago, but the switch had me chasing wiring diagrams. The video somewhat appears to reinforce that. However, since the module is in place and presumably connected on your car, I'd rather not say "Go for it!" and burn something out, up, or to the ground. That's why I want to go look at my '74, because I'm sure it's wired differently. I was busy on Saturday, and we got some winter weather (snow and freezing rain) Saturday evening. I was not walking 3-4 blocks on icy roads yesterday to go look at it.

When making adjustments to the steering column, the toe-plate bolts (that bolt the column to the firewall) don't really allow much adjustment. Usually loosening the two clamp bolts that hold the column to the toe plate is enough to jockey the column around a bit, including fore/aft to some extent.

Don't remove all five bolts at the same time. That just creates a major pain in the ass.
 
OK was just hoping to ease your searching pain.
I may do it again & see if I can find the other switch & how thats internals work.
If they switched to a magnetic coil that's how most of my A/C relays worked, but always to pull in (or let out) a set of contacts, hence closing the points to connect the 2 yellow wires, that's how my mind works, weather it's copasetic I have no idea!
 
Not finding much, but did run across this, looks like your box?


I have no idea what an AMC seatbelt override box looks like. But as a former owner of a 1974 Dodge Dart I do have some experience with Mopar. For them, you tie the two yellow wires together at the box and you are done. I opened the box up and internally connected the two to make it look clean but I'm kind of anal sometimes.

Still digging through boxes, trying to sort out the garbage & get anything I missed ready to go on.
one bag had grill hardware in it, not even sure where it came from, this car had not a lot of grille on it when I got it, but it (the bag) had 4 of the retainers that go in the header panel & a bunch of hard ware, so I got the ole tumbler running again in case I need any or all of it! 20231211_153839.jpgNot sure about these, I think the skinny onesare off seats, not sure what the thicker ones are? 20231211_152220.jpgfound 2 more wire clips, how do you use these, tape the wires to them?20231211_153605.jpg& pulled out the heater valve cable, not in great shape, & the firewall plug is nowhere near that gigantic hole I have left???

That looks like the switch I have. And on mine, the internal contact points I've already soldered shut would connect the two yellow wires on that plug. Those also look like the plugs on my car. As I've noted already, mine has two separate plugs, one of which is red, so I believe this is a later design not shown in the factory wiring diagrams (which is the same as your harness). In the photo I have of my engine bay, I can't really tell where the wires go

In terms of your AC relays, the switch I have could be considered a "manual relay". With the key on, the coil is energized but it's not powerful enough to pull the contacts together. Pushing the button forces the contacts together, and a steel plate to which they're fastened against the electromagnet, holding them together.

If you compare the "T" configuration in the photo above to how the wires are arranged in the "T" on your car, you might better understand my previous confusion. The cavity with the yellow/traceer wire in the photo would be blue on your car. My switch, in your harness, would connect the non-tracer yellow to the blue wire, which is 12V+ with the key on. That would just backfeed 12V to the ignition switch via the interlock module.
 
OK how bout the ole switch-a-roo.
I move my yellow wire to the blue cavity.
If we are jumping the 2 yellows there's no need for the blue to heat the non existent coil & or the black ground for that?
 
Now that we brought hvac into this I'm wondering if I saved a fan relay or 2, I had dozens on the truck before I (broke my heart) junked most of it. will dig tomorrow!
 
I think I found what I found what they did with the heater cable, or maybe the hood release?
Dug out the old firewall plugs & found one that fit that hole.
I'll see how it routs from that hole, but that one may be better for the hood release routing?
The made a hole in the big plug to slide the smaller one in 20231212_162230.jpg

The problem is, your connector still won't fit my switch. I was thinking that I'll send you the (cleaned up) connectors off my car along with the switch, and you can un-pin your terminals and install them in the connectors I have. Unpinning isn't difficult; you can do it with a small pick or even a straightened paper clip. I'll just disconnect the wires to the coil winding. The terminals I already soldered connect the yellows if you arrange them the way they are in the picture you posted above. I'll label the cavities so you know where each wire should go, though, so you don't have to dig the picture up again. It'll look factory and work like a champ, completely bypassing the entire system almost as if it were designed that way... it sorta was, after all.

I was thinking about this last night, and about my high-school best friend's '74 'Cuda. I was all over that car in the six years or so I was involved. I spent lots of time under the hood, of course, but between that, pulling the cluster (tried to swap to a Rallye cluster; didn't have all the parts), changing a heater core, and yanking the carpet to patch the floor, I never saw a single trace of the seat belt interlock system. No override switch or extra yellow wires under the hood, no connection for a module behind the cluster, no seat or belt switches. In fact, it didn't have integrated 3-point seat belts either. It only had lap belts, and they didn't even have the pegs for separate shoulder belts. There's absolutely no way it was built without integrated lap/shoulder belts, but there were no gaps in the headliner. Someone went to great lengths to un-1974 that car. I know the fella from whom he bought it; that guy would've left cut wires everywhere.

Regardless, mystery apparently solved in this case.

That's definitely the factory hole for the interior hood release cable. The cable should have a grommet along its length that pops into that hole.
 
My cable had a smaller grommet, that fit one of the other 2 holes, hood release left one, I'll have to pull that & switch it with the heater cable, since that cable goes right & the hood runs along the inner fender.

K, she's on the ground!
I started with 15 turns each on the torsion bars, not quite there I couldn't get my jack out from under the K frame, good thing again the extra jacks are here.20231213_150052.jpgbout 20 more 1/4 turns, off the jack but still low20231213_145101.jpg15 more20231213_145105.jpg& 20 more I'm close & will stop here for now, if I remember from when mine was brandy new back in the dark ages they sat pretty level, now how level my yard is, is another question but & measured to the front & rear of all 4 rockers & there all about 8 3/4" up.20231213_152520.jpg
Exhaust is pretty low, wondering if there's any twisty maneuvers I can do to raise it a little? 20231213_152548.jpg
 
Might have the carpet to a point where I can live with it, my interior guy stopped by to see if he could get the lumps out, that was a NO, but he said I had the carpet way back from where it needed to be & it might be a little better if it were moved forward quite a bit. made 2 cuts on the front edge to get it where I think it should be, 20231213_160624.jpgDrivers side I need to do the corner again, but there's only 1 small lump now.20231213_160444.jpgPassenger side still has that nasty one on the floor, but the corners are much better, I may try & glue a couple of spots at the end if all else fails? 20231213_160515.jpg20231213_160524.jpg
 
Back to parts up for grabs, rad frame, I think another ebay item I bought for nothing
1 side has a # the other does not.
20231213_161655.jpg20231213_161702.jpgA set of wiskers, I think for the top of door panels, have no idea why I have extras? 20231213_162702.jpg& when I was putting it back in the box I hit these, now I just bought another set, more money tossed out the window!
Quarter window rubbers. 20231213_162910.jpg
 
Jass man, a box of goodies should be there soon, it's heavy so watch your back!
I did receive the box. My apologies on my failure to acknowledge and thank you... I got busy shortly thereafter and completely forgot to do so. I feel like a heel... sorry, and thank you very much. You sure I don't owe you anything for the shipping? That had to be expensive!
 
Nope, pay it forward, anything I send is saving it from either the trash or the scrap yard.
Use what you can, give away what a friend may need you have a ton more contacts than I do here, sell what you can.
I would like to see anything that might be of use go to a good home than end up as junk.
You may also toss anything I send that may be useless, you know what that would be better than I.
It's the only way I have to thank you guys for all your help.

Would you know if those quarter window rubbers are the same on a challe as the cuda & even the door panel strips I posted, if so they are yours too!
