I came across a problem with my wiper harness from YO. The two wires which are on the plug connecter on the left side ( red and brown) were crossed. they were ok on the harness at the wiper motor. I know there are four total wires so I checked everything. I had to add the a/c harness (2 wires). Just be careful, check everything out. this was on a simple harness, now I have to check my new dash harness and forwarg lamp harness.
