Hi Looking to install a kill switch to fuel pump of my 90 suburban. After looking at the wiring diagram, I am wondering where would be best to wire it in. Should I wire it in between the fuse panel and FP relay (20amp) or directly before the wire goes into the gas tank. There is also the possibility of wiring it between the ignition and the FP relay (trigger to FP relay). I am leaning on down close to the tank, but wanted to know what others had done. I don't want to screw the ecm up.
Thanks Brad
