get the resisitor box of a 90 or so crx, or prelude, itll plug right into your harness, theres a black and yellow wire running from the harenss to the injectors that needs to be cut and positives and grounds have to be wired to the injectors...........i could help you out depending on where you live.........but you live in nova, so your gonna need some help rom up there.........

damn 550s might be a little to much unless you have a super afc or some kind of fuel management

You need to make sure they are low impedance injectors. If they are then yes. If they aren't you don't need to change anything but the injectors. You don't wanna mess up your computer cause you thought you knew what you had.

Call the company and check or use a digital voltmeter and check ohms through them.

**Wrong teminology
