Question Intake Air temp Sensor
Im unsure which is the color code of the air temp sensor. Does anybody know?
I aquired a second hand wiring harness and well I have had to figure some of it out myself.

By the way, I bought a LS3 serpentine kit and the AC comp does not fit. I will sell it with the belt and mounting kit for a fair price. I need AC!

What is the harness out of? What do you mean by color? Connector color, wire colors?

Question
98 camaro wiring harness.

I believe the connector to the air temp sensor was cut off.

I would need the wire color code to the sensor.

Get a different harness. What PCM are you planning on running? 98's are junk.

You will need to repin the PCM part of that harness to run a newer PCM. What MAF are you looking to run, if you are planning on a 85mm, get the correct harness now and be done with it.
