Ok I have a 1989 camaro RS and when I purchase it a year ago it had both window operation off one switch so i purchase the drivers side and notice that I have to operater both switches at the same time to lower & rise windows. Can anyone give met the right wiring color code to make sure there not cross. Someone mention ground them both to the chassis. Also notice the oil pressure gage not work but when you miss with key it jumps and goes back down.
