does anyone know what the main relay powers?



as far as i know, the b/y powers my coils and the b/w goes to my ecu and the connector to my ecu code checker.



there are two other wires, a black with a green stripe and a white with a blue stripe and i can't figure out what they connect to.



i've tried wiring diagrams and they tend to have different colors than my wires :/



im also curious if anyone knows what else the circuit opening relay powers besides my fuel pump, starter, and another prong on the emissions harness. i know the top middle b/w is power.



any input would be pretty valuable information https://www.nopistons.com/forums/pub...#>/biggrin.gif

im pretty sure the main relay powers the injectors and coils the black and white wire to the coils is the same wire thats black and yellow on your injectors but its not really black and yellow its black and white. most engine bay wires from the heat or other contaminates tend to dry out and change color its normal on any 20+ year old car

gah, discoloration. cool. lol



from what i understand, the two-prong connector powers up the electromagnetic mechanism inside of the relay and the )armatures?) complete or bridge the circuit on the four-prong connector. what i wanna know now is what do the other two wires go to if the other two power the b/w or b/y.



by chance, can anyone tell me what the circuit opening relay controls too? i know the starter, fuel pump, and some other emissions harness connector is linked to it, but i still dont FULLY understand.
