need injector resistor help.

i just installed the kg fuel rail and injectors.850/1600cc.they come with 4 inline resistors for the injectors.where do i tap them in at? what color? any help or diagram would be great.thanks,jay

Safest bet is to tap them into the harness down by the ecu so they're not exposed to vibration and heat. They go on the ground for the inj. All you need is the ecu pinout. Do a search for the fsm.

A better option would be to get an FJO injector driver. It will convert the saturated pulse to a peak/hold and will work with low or high impedance injectors. You can get a Denso to Bosch conversion harness at one of the E-85 conversion stores and not even have to cut your stock engine harness.

Never used the adaptor harnesses, I'll have to check that out. That would be nice rather than cutting the harness. How much are they?

RC engineering sells them for $18, but I found them cheaper last time I did a search. Here is a link to RC http://www.rceng.com/Denso-Clip-Connector-P48C9.aspx

I misunderstood, I thought you meant something different.

well my harness was already cut.and i didnt know if anyone has done this before.and just needed some help.if you have and have any pics please let me know.thanks,jay

Im in the middle of installing the KGParts fuel system too.
I'm no ecu pro and the kit did not come with instructions.
Does this seem right?
My MS-Paint skills though, are badass

Just checked with the RX7club - i'm correct as usual
