Hello.

I'm using a F23 harness, and I need help with the installation of the resistor box in a H22 swap.
On my resistor box I have 5 wires, four black and a red. I was wondering what that fifth wire could be? Is it for ground?

Thanks

 

If I'm not mistaken (which I may be) the four reds are negative to the injectors and the black is positive for power which all the injector positives go into. I think this is the way my resistor is hooked up and it works (been a year since I've done it). I would definately get another opinion though.

 

Thanks for the information.
Anyone else?

Thanks in advance.
