I just got a set of 720cc injectors, and They have the peg in the center instead of offset. My car is an 88 10th AE, and has the resistor box behind the passenger headlight, so what im asking is if i can just change the clips. Thanks

i think since its an 88 the box is just for the fuel pump right? What will happen to my high imp. primarys if i plug a resistor box in? Will it plug right in? If i cant use that, after my searching i saw that i need to wire a 10ohm resistor inline with the clips right? Thanks for the help

Yes, you need to install resistor inline somewhere in the wiring.
If you don't do this, you're going to fry the ECU.
No, a resistor box off a pre 87.5 FC is not going to just plug-in - you need the ENTIRE engine wiring harness to do that.

Just get a small file and file off the "key" to make the fuel injector plug right in.

Thank you very much for your reply! Im excited that someone answered. Just one more question, If i wire in the 10ohm/10watt resistor will it get hot an possibly melt things? I need some advice, because it scares me to cut the harness.

Those "sandblock" resistors are designed to stay cool.
I wouldn't worry too much about them.
If you're really paranoid, I would step up to a 20-watt type.

the 10ohm/20watt resistor wont get as hot? Would it be a problem if it was wrapped in electrical tape? Thats good to know, i guess ill have to go look at radioshack for some tomorrow.

Yes, the 20-watt versions are physically larger (than the 10-watt ones).
The larger resistor helps with handling more heat, thus the higher wattage rating.

No, don't wrap it in electrical tape - that just keeps the heat in.
Just add the resistors and cover the bare wire ends.
Keep the ceramic body of the resistor open to air.
