I spent most of the day doing the wiring. I wired the LS coils/Injectors to the original L98 INJ1 and INJ2 circuits.The wires from the old L98 harness to the LS PCM have been extended. Th grounds are hooked up and the 12V switched have been wired to a fuse block I screwed in under the drivers side hood latch frame rail. I figured its protected from something randomly dropped in the engine bay and the weather there.
