quick wiring question

[JFarhanbod]

Hey guys, I'm plugging in all the sensors in my e30 and I had a couple of questions.

What colors are the wires on the following plugs?

Crank Position
Idle Control Valve
Throttle Position Sensor
Reverse Lights

Also where does the oil pressure sensor plug into? and what sensor plugs into the e34 pan?

I am using the e34 harness by the way

If no one chimes in, you can find it in the ETM for your harness. http://wedophones.com/BMWManualsLead.htm

figured out the oil pressure sensor.

all thats left is crank position, icv, tps, reverse, and oil level sensor

anyone know the colors of the wires that go to each? that would be a great help.

[JFarhanbod]

went through etm and so far got
Crank: Black, Yellow

[JFarhanbod]

alright got everything figured out except for one wire thats brown/gray which according to this is iat but there is already an iat? any suggestions?

In respect to an OBD1 (VANOS) harness. Taking into consideration wire lengths, the only connectors you can easily mess up are IAT, Vanos, and the two coolant temp sensors.
Crank connector is a coax (very thin gauge) wire, hard plastic
IAT is as you mentioned gray and brown
ICV is a short 3 pin that has white/something, white/something, and white/something off the top of my head
Reverse lights are long as hell, grn/white and blue/yellow(i think)

^that picture doesnt have the cluster coolant temp sensor listed?
its brown/yellow and brn/purple.

i dont think my harness has the reverse lights, its an e34 harness

Yeah dude you should have TWO coolant temp plugs.. one for DME and one for cluster

[JFarhanbod]

I got the coolant ports down. Only thing is that I don't have a reverse thing

E30 has reverse wiring on the body harness unlike e34/36
