Well, i have a disaster. My whole computer side of my harness is gone, and i have the new senind units, but no plugs, just colord wires. It is a 90 Camaro with a original v-6. I need to know what color is the oil sender wire and the coolent sender wire. Also, about this speedo thing. What color wire runs down to the transmission?

 

as far as the oil sender wire and coolant temperature sensor wire. They should be pretty easy to locate. They are on the driver side i belive and one wire should have a little plastic piece on it that slides over the coolant sensor most of these wires ive seen are brown. While the other one should be really close by it for the oil sensor. As for the wire that runs down to the trans there are two the wire that goes to the speedo sensor is yellow and purple and the other one really close to that should look like a cube and controls you trans lock up (if it is an auto)

 

ought to be able to find wiring diagram in your manual.

 

I have no Manual. maybe will have to go out and buy one, eh? See, there is no ends right now, so i have to start from scratch, wut a pain. O well, i will just have to start from there. If i am right there should be no volts going to these wires, right?
