Help! Hacked up wire harness.

[CaptainPainn]

Anyone have any information on these latest wires? Been at it for awhile and have made no headway.

First off, none of them are necessary to get the car running. The pink female should plug into the fuse box(onto the terminal marked "ign" and the male is there for "optional equipment", the wide plug with the two yellows and the flat 5-pin I believe are to do with seat belt/key buzzer. The 3 pin with the brown/pink/black I think might be for the A/C controls.

Captain here is a pic' of a part from eBay with the plugs and some wire (for your colours) to maybe help out. Harry

That is the correct neutral safety plug in Harry's pic of the shifter, but the reverse light switch plug should be pink and light green.

That is odd Spencer, as there is a second shifter with the same colour scheme but with a harder pic' to see! Did the General change the colours at some point mid stream? Or am I just not as visually acute.

checked and these aren't the same seller just to be sure. Harry

Sorry about that; I stand corrected. Just checked the diagrams, and unlike all the other GM vehicles from the 60's right through the 80's, the later h-bodies did indeed have different reverse light colors. The tan is the ign. feed(it splits off at the signal flasher) and the dk. blue is the reverse light wire. It changes to the usual "corporate" lt. green at the main connector under the dash going to the back of the car.

EDIT: In my defense, I just checked all the different year diagrams from 71-78, and the change to blue/tan happened in 77. The OP stated in his first post in this thread that the harness was from a 75, so that's what I referred back to for each "mystery" wire.

Thanks for the pictures, really clear up a few questions for me. So both the neutral safety switch and the back up light switch are contained within the shifter. Since i'm going auto, and the harness is manual, i presume that ill have to reroute the back up wires from outside the firewall to the shifter. I decided to go with 700r4 instead of a th350, and i have a shifter from an 86 Camaro that i think i should be able to get to work. Th biggest problem i have now is finding the d*** neutral safety wires.

If your harness is from a manual trans car, the plug with the two purple wires should be somewhere to the left of the steering column where they used to plug into the clutch switch. The connector is the same as in pic of the automatic shifter. Very often, they get jumpered together so the car can be started without actually getting in the seat and pushing in the clutch with your foot.

went out and looked today. FOUND IT! after just 5 minutes. the wire isnt very long, and originates from the fuse box. it was tucked back behind the fuse box and break pedal assembly. could not have found it if i had not dropped the dash. jumped the terminals and turned the key. starter engages!

I wanna say thanks to everyone who have posted so far. The help has been immensefull. This light here has long wires. I was thinking it might go to the shifter, but it does not turn on when i turn the lights on. It turns on when i turn the key on, but then goes off after a second or two. It does not always come on with the key, and nothing else seems to affect it. The colors are yellow and black. Still need help with wire 10.

This is the shifter i will be using for the 700r4. Not sure which wires go where. I'm pretty sure one set go to the safety and the other to the reverse, but what about the other set? Shifter is from 85 or 86 Camaro.

Large yellow and purple are the neutral safety and go to the purple/white and purple clutch switch plug you found beside the fuse box. Dk. blue and light green go to the reverse light connector with the pink and light green you found out under the tunnel.
You can ignore the orange/black and black/white; they were for a "ground when in park or neutral" input to the computer.

Thank you for posting this. Makes me feel better about my wiring issues.

Keep going....
