So i have a 1995 k1500 that i am currently putting a 550hp 400sbc(holley sniper 2 EFI) with a 4l80(stand alone transmission controller). My question here is what do i need to do with the oem wiring harness to still have all of my lights, turn signals, all that bs. i might just be stupid but im not the most educated on these trucks. The motor or tranny WILL NOT be controlled the oem controller. also using the holley pro dash so none of the original cluster/wires will be needed.
