Nothing to report. Job just keeps ratcheting up the self-loathing factors. Not only will I never get to customize anything, I'll have to do all sanding of all items on all jobs including that which others have customized halfheartedly. To me, that is teeth kick on top of face spit. Bike rally smack dab in the center of my commute bottleneck this week so I made me a temporary sticker.

Bonus!

I run with a hub unplugged to defeat ABS and TCS (traction control) and had tape over the TCS indicator and cardboard over the ABS one, which is real bright.

After my experimentation and disconnecting one wire, now the ABS light is not on. But traction control "off" indicator is lit.

I have no explanation of how this is even possible. But I'll take it.

For the record, without lockup MPG has not changed by so much as a tenth of a mile in two tanks of gas. But I constantly miss cruise control, it was an important weapon in my fight to retain freedom.

I'd be more concerned that an object or varmint might get caught between tire and bracket or fender. A skunk got hung up in the duallys on the school bus once. But look at how close tire tread rides to McPherson struts on any modern vehicle.

Removed purple wire from blue connector and plugged it back in. No change, no lockup, no cruise. End of story.

Nope. I hope Chevy mops the courtroom floor with whatever human told a computer to make that vid.

Well, nope. Swing and a miss. I got my phone down there.

Looks to me like the top switch is red and brown.

The big switch with the blue connector unplugged has a two wire plug, orange and tan (?).

Then the four wire plug is:

red, dual dk grn / wht, orange (or pink?) and purple.

Been driving it a couple days with the blue plug unplugged as shown. When and if I get up around 50, well I'm  not sure what might be going on. Could be some trans issue, could be me getting used to no lockup. The 3-4 shift seems like a bigger spread without it. After it shifts to fourth I tend to let off the gas anticipating lockup which normally hurls it a few mph faster. Additional throttle required to hold speed.

So I am hyper-wary and trying to mentally prepare for whatever. It manages a slight exhaust note now at least. If quiet and glass is open. No dip in MPG yet and WOT is good. But up to 50ish is all I know about. Seems good thus far.

Thanks. 

I wondered about shift interlock but when that was unaffected by anything I tried, I changed my assumption.

As soon as I can get under the dash again, I will see whether your wire colors jive with whats there. Staying home from work today due to back damage done doing that very thing too soon after hurting it lifting pickup body panels. Visual access to brake switch requires hooking heels over headrest.

Again, thanks.

Alright then. Any suggestions for a course of action which might enable me to form a theory about which wires are cruise and which are TCC?

It seems I have generated another unanswerable question and will not get cruise back. No big deal but I used it a lot to stay out of trouble.

This is a very common GM brake / cruise / TCC switch design from the era surrounding the turn of the century. Can anyone tell me which two wires in the four pin connector are cruise and which two are torque converter? Lamps are in the two pin one.

TIA

Name any GM car (besides GN) 1984-1993 which is valuable now. I'll wait...


That was the automotive soul killing decade. Best forgotten. All unwanted everything. Ugly and clunky. Theres one at the shop I've used as a junk bin for the last decade. Owner died, nobody wants it.

...aaand as we've all come to expect of me...

Sunshine means storms ahead. I now have GTP torque converter oscillation. Deep inhale, barely exhale. Trans job will be 4K+ now I bet.

Oh... the personal heap junk I actually came to report:

DD GTP threw a P0341 last week (cam sensor DTC) so I replaced the ignition coils with a new set of three from one box for a hun in Walker brand, from O'R. Beats buying them seperately by a long shot and if theres a dud something can be done about it.

I still prefer to picture tall and dangerous pink skinned jungle archery enthusiasts when I hear Amazon.

Car runs great now though. 323K and not even breathing hard yet. She's a marathon runner. The purple sanity preservation device is still operative as well. Weather is lovely. Enjoy labor day.

The 71 GMC job has been handed off to the next guy. The 73 Ford job is in final urethane primer now. Right door and fender (originals) required some fill fudge to match up body line at gap. Boss told me my next task is to resume the 75 Bronco job (bottom of pic). That one was paused once it was screwed together with new metal. My all-knowing coworker tells me no, it is the basket case Bronco (top of pic).

Yeah not much use for any highway friendly final drive ratio there.

Reminds me of a Charles Bronson movie series. 

Well, I didn't write any of that. Just linked to an article with an older article pictured within. Not able to see the vid you posted.

Don't forget about dirt roads.
