I got some GTR injectors and also the register drop or resistor pack or whatever you want to call it. I just need to figure out how to connect it. If anyone has any idea please reply

Try the RB26DETT FSM.

Or aussie forums.

Info on this forum is going to be limited.

I just wired one up last week. Do you have the GTR resistor pack to wire or are you going chinsy with some genaric *** resistors?I can help though

yeah i have the oem resister pack for the GTR it has a 7 pin connector on it and i dont know where i need to splice those wires to or if maybe they plug straight in a connector but i dont see any plug that looks similar. Thanks

It wont plug right into your car buddy. To understand how to hook the resistor up you must first know something about injectors.Injectors have 2 leads (12v, and basically the on/off from the ecu)

The rb20det has high impedience injectors meaning the 12v side or the injector harness is strickly from the battery no resistor.

GTR injectors run a resistor to lower the current.

To wire the gtr resistor you need to find the common wire to all injectors. This can be found by removing the electrical tape on the harness with injector 1-3. One side of the injector should have a black/white wire that is the power wire. cut this wire closest to the ecu ( off of injector 3) and splice in the miscolored wire on your resistor pack (pin 3) this should now give you power to the resistor. Now that you have cut the imput power to all your injectors you have to run the other six wires on the resistor to the black/white wire on each injector.

Hook it up like this Pin #1 on the plug goes to injector #1, pin #7 goes to injector #2, pin #3 is the power already hooked up, pin #5 goes to injector #3, pin 8 goes to injector #4, pin #4 goes to injector #5, and pin #6 goes to injector number 6.

That is it if you still dont understand i will send you some diagrams

Thanks so much - i kind of understand but a diagram would be very helpful. I just want to make sure i hook it up right. Thanks for your patience and help.

Just simply look at a rb26dett wiring diagram and compare it to a rb20det. If you still dont understand ill try to explain it better.
