I am starting to tackle another section of botched wiring created by the previous owners of my car 1984 L69 5 speed. I am working on the radio section because that is where I am installing my A/F gauge. Behind the radio I found this connector hooked to nothing. I am guessing something with the HVAC? Can anyone confirm and also tell me if any line is 12V switched that I can use for the meter. The blue line goes hot with ignition according to my meter but I want to make sure it is a clean 12V switched not something else weird.

 

That's the park neutral switch connectot

 

Did these come in T5 cars?

OK that could explain some other mysteries like why my reverse lights don't work or have a harness to plug into. So just to clarify the blue wire in the switch is the blue wire the arrow points to in this picture?

Also is the green wire on this plug the back up wire green line in the diagram?

If it is can I just wire the reverse switch in my T5 Between them and get backup lights?

 

Most Firebirds were wired for Auto AND Stick. Camaros on the other hand were either wired for Auto OR Stick.

Check that reverse switch on the side of the tranny case to be sure it's still plugged in as it should be. ( Yes,... Reverse light wires are BLUE and GREEN. ) There's a good chance the reverse light switch on the tranny is bad and simply needs to be replaced.

 

The switch may be bad but unfortunately the previous owner for some reason deleted the pigtail going to the tranny and the wires associated with it. I cannot find them anywhere and I had the carpet out at one point.

I was going to get a pigtail like this one and then wire in my own with a relay but if I can use the factory wiring that would be a good thing

This info is for the 84 Camaro,..... Pretty sure that it's the same for the Firebird:




C207 is the 2 connector plugs under the pass side of the dash harness that connect to the ECM harness. If the ECM harness was removed from your car than the 2 wires leading to the Tranny are probably gone too.

To get your Reverse lights going again just buy a replacement plug, connect it to the tranny and run the 2 wires back into the car to the C207 connector ( however you choose ) and splice into PINs "B" and "G". ( You could also run the 2 wires from the tranny thru the shifter hole in the tunnel - under the floor boot - and splice into the Auto shifter NSS GREEN and BLUE wires too. )

 

That connector in your hand is the auto shifter connector. Purple & yellow are the neutral safety switch; orange & black are the dash light in it; the others, at least one, is the reverse lights.

None of those are ignition-switched 12V.

The pigtail for the T-5 reverse lights breaks out of the big harness that goes over the bell housing, just to the driver's side of the center of the engine. As detailed above it contains only 1 blue and a green wire. It is NOT in the interior at all, which would of course explain why you didn't find it under the carpet.

I would recommend avoiding splicing ANYTHING, or running new wires, except as an absolute last resort, no matter how hacked up stuff already is. 2 wrong hacks don't make a right one. Life will be less stressful in the end if you figure out how to UN-hack stuff rather than finding new ways to hack it up some more.

There's an ign terminal in the fuse box you could use; and there's also the terminal block up above the parking brake release that the factory put there for its own requirements for just such things, both switched and constant. (PW, PS, PM, PDL, etc. etc.)

 

I guess I should have been clearer The Reverse harness is absolutely not in the car any more. It was removed for some reason, it is not under the hood, cut off and hidden in the interior or under the car. Also the mate to that connector is 100% missing and hacked out of the car.

 

Have you looked where I described?

Even if it has been sodomized off, the rapist probably didn't expend any more effort than absolutely necessary on doing so. If you open up that big split loom from about the upper left BH bolt back toward the brake booster, you should be able to find its remains, and maybe just replace the pigtail. It's a pretty standard 2-pin Weatherpak, shouldn't be hard to find a suitable one on a junk car. Looks like this https://www.clipsandfasteners.com/Do...l_p/a15952.htm you might even be able to pick that up at AZ or some such.

 

I looked again where you said and even in the wrap and found nothing. The previous owner cut a lot of wires back at the firewall connector including the oil and temp gauge wires and other wires in other places. All in the name of getting rid of that "quadra junk" and making it "old school" Wish I knew how scary those words were back in the day. It is getting dark now I will check when it is lighter. I already ordered that pigtail so I can fix things when the time comes.

 

What a shame... butt yah. "They" do stuff like that.

With what John posted up there, you should be able to locate the right place to hook it back up to. Good info.
