Wiring from hell..... Need help!

[Janz99]

Hey guys, i know this is alot to ask from ppl, but im hopeing there is a few ppl out there that know the wiring in these cars like the back of their hands. I bought this car in pieces, and its the first supra ive ever owned, so i didnt have the luxury of taking the wiring out of the car to see where it goes back. Car is a 87 hard top, originaly was an auto i believe, previous owner swapped 5 speed.

So onto the part needing help.... We are building a race car, and we are eliminating everything that doesnt need to be in there. I have hooked up alot of the stuff that i knew where it went, but there is still a ton that im unsure of. I dont want to get rid of anything unless i know where it goes.

Here goes. The first harness i am working on, is the dash harness. Here are the plugs im not sure where they go:

i know this part is obviosuly broken, but im wondering what it was for in the first place:

This is the first batch of plugs im not sure of. If anyone can clear this up, that would be greatly apreaciated!

Alright well I want to let you know that I would keep your harness bascially unless you're doing a stand alone, you will find out that the car will not even start without most wires hooked up.

We are doing a full aem/cdi setup in the car. The aem doesnt need much to get the car up and running. The whole idea is to clean up and simplify the wiring that isnt needed, to make the car easier to work on and diagnose if theres a problem down the road.

last two are sensors for the automatic climate control, they go near the corners of the A pillars..

The last 2 pictures are of the same thing, just different angles. Good to know there is suppose to be 2 of them though!

Thanks again for the help guys. I'll see if i can figure this out with the link provided!

no prob..

also this one..

has a bulb with a green condom. The only things in the interior that have that are the key ring, under dash light, so that might be for the turn signal stalks, horn, cruise, etc...

not 100% sure but it definitely looks so..

where is the plug located? passenger side or driver? if it's the passenger side near the ecu, it looks like the plug that sends a signal to the tach, oil pressure, and coolant gauge.
