Wiring harnesses

If you go EZ (and youre using an MSD) use the schematic below and you'll be fine.

I used the EZ kit and it went great. Took a while, but I worked slow. I have A LOT of aftermarket parts. Digital dash, 12 different sensors, relay boards, nitrous system, 2 fuel pumps, EFI, etc...EZ kit handled it all.
