Supra Injectors on honda
 

Well i just picked up some 440cc supra injectors and i was lookin at them seeing how im supposed to wire them to my stock injector wires. Theyre are a bunch of different color wires and not one common one. So im asking any one who has installed them to please help me dtermine the power wire so i can get these bitches on.

PM Fabrik8 or VR-4ever maybe they can help you out.

looks like all of them have one white wire, then a diff color wire.

The white wire would be the voltage feed, and the off color wire would be your ground or pulse wire.

Not sure if supra's have a resistor box or not, but you def want to double check. Otherwise if they do and you don't add one, start looking for a new ECU.

well here are the color combinations.

Red and white
Red and white
yellow and white/blue stripe
yellow and white/green stripe
Black and white/redstripe

Even the though the white wires are different in color theyre all pinned on the same side of the clip. I dont know if i should take my chances. What could happen if i wire them wrong. These are low impedence injectors and yes i will be using 10 watt 10ohm resistors on them.

well honestly I don't think it would really matter...its just basically a 12v solenoid, should work either way you wire it. Just be sure when you wire one one way, that you wire the other 3 the same as well.

thats what i was told by someone on h-t.

Re: Supra Injectors on honda
 

those are MKIII injectors huh? you will need the resistor box

Re: Supra Injectors on honda
 

With those, it doesn't matter what the wire shield color is, you're passing current through either way.

Put one lead of each to ecu and the other lead of each to the resistor box.

or wire them in the way your stock injectors were, and use inline resistors. might be easier for you to do it that way than adding a resistor box and mounting it somewhere.
