 Re: LS1 swap into 1990 Chevy Truck
you can make the truck guages work just by tapping into the existing wiring. i didn't hook up the existing brake wiring. i just bypassed all that and made the blinkers and brakes work. still need to hook up the reverse lights, that should be simple. i just cut off the ls1 harness bulk connector and connected all of the pink wires to 12 volts thru fuses. you can use the existing PPL, purple wire, for the starter or the one that's on the ls1 harness. i'm opting for removing all of the stock guages and installing autometer gauges. just started that.
email for questions.
good luck
