My fuel injector subharness is all cut up from the previous owner. Its a blacktop harness off a 180. I looked everywhere and couldn't find a solution. I have 8 wires, 4 red, blue, green, yellow, and white. Anyone know which one goes to which injector?

You post is missing some pertinent info, such a the model year. You could try looking through the FSM. There's a link in my sig line.

There are only 5 wires for the injectors. There should be a common 12 V power wire and 4 separate grounds to the ECM. If you want factory wire colors, compare them to page EC-133 of the USDM FSM. The wires are the same between a KA and an SR.

Any other wires on the stalk for the injectors typicall go to the IACV, the AAC, and the knock sensor.

edit: thanks for the replies. Theres 8 wires cut up and 4 of them are red, a green, blue, yellow, and white. I have injector clips and cannot find where to soder them together. The car I have is a 240, engine and ecu is a redtop sr, and harness is a blacktop.

I told you where to look in the service manual to get the answer you need. But I'll play along and spoon feed you further.

red - 12v constant to each injector. Probably splits into 4 wires in the main stalk of the harness.
white/black injector 1
yellow/black injector 2
green/black injector 3
blue/black injector 4
