I have a new to me 91 4runner that has 2 PIAA lights on the front. There is a toggle switch with an up, down, and middle(off) position. the lights on the front have 1 yellow and 1 clear light each. However, when i toggle up or down i get one yellow light on one side and 1 clear light on the other side turned on. Anyone know how I should reverse the wires to get it right?

 

probably your best shot is to put a volt meter on it ... dont wanna blow somethin in your ecu over a set of lights...
