Cruise Control on a '70 Challenger

E Body lever, wiring harness, and brake switch

---

This is my setup. I'm using the lever, and possibly the brake switch. I sent that 70 e body wiring harness to M&H electric and had them build me a brand new one. Now that they have a diagram of how to make it, you should be able to call them and order one for yourself. M&H makes good stuff. They supply all of Year One's wiring harnesses. Due to limited parts availability (grommet) you won't find this harness in the Year One catalog. Call M&H direct to get it.

For the brake switch, they didn't change much up to the early 80's I think. Part # changed, but only difference I could find was the color of the wire.

I agree that the E body switch is different from the B body. I do have a B body switch installed in my 'Cuda and it works fine.

And because you can't find an original one & also because the E body ones aren't chromed like all the others.. What I've done in the past is take two easily found switches, strip the electrical out of both of them, cut one near the area where the switch fits, cut the other the proper length to equal a real E body lever then weld the two pieces together... Laying them in V blocks will keep them straight, tack around the tube like doing body work, then grind it smooth... chucking it in a drill press makes getting the whole lever sanded for paint a breeze, clamp the area where it bolts to the T/S switch in a vise, heat the area just past the vise with a torch & adjust the lever angle... Prime, paint & reinstall the electrical & you now have a switch that no one will question...

I might try that sometime Randy.

Here is an exploded view of a B body lever (also typical of E body).
Dissassembly not for the weak of heart. The chrome ring that you rotate for acceleration is Fragile, and the black plastic is Not meant to come off of the metal stalk.

This is the one I'm currently using on my 'Cuda.

The head, switch, and lettering is the same for all.

I Disagree with that statement. I've found 3 variations, and would be happy if anyone could tell me what years/cars they go with. (or maybe they were just made by a different vendor?)

See Pics...

This first picture is an E body lever. I was told it came out of a 70 Challenger.

If I'm not mistaken the wiring harness itself can be scavenged off of practically any car with factory cruise all the way through probably at least the mid 70's.

My '70 Challenger R/T w/auto in the console is coded for cruise control, but the steering column was replaced at some time in the past and the wiring and control stick are long gone. Is the stick a standard part across mopars, or specific to my car? If specific, is anyone reproducing this?

Thanks

I'd love to hear more about your car. Do you still have any of the underhood cruise parts? The Servo bracket is E body specific and is tough to find, just like the turn lever.

The Servo itself, brake booster bracket, and throttle cable clamp can be scavenged from other cars. The throttle clamp is different for big block vs. small block. Big block left in photo, Small block right in photo.

As stated above 68-69 B-body is similar to E-body but has a shorter handle.
Both have small black button on end.

Terry this is the first time I've seen you post something I don't agree with... I've owned two factory cruise control Challengers, both had the larger button like posted in Tav's second picture above... Can't really see it well enough to tell which style handle it is but this car is coded for it & I bought it back in 74..
