Holley HP EFI Install for a Street Car
Hey all,
Attempting to install a LS3 with a Holley HP EFI system into a street car and keep all existing functionality of a 1994 Firehawk.
While the Holley install seems straightforward, how do I go about keeping all the existing functionality such as AC, cruise and even backup lights without the original ECM? Or do I keep ecm for just this functionality.
Any help is greatly appreciated!

That's a tough one since the Holley EFI isn't really designed for a modern street car that is still utilizing all the accessories. On my '95, I have the Holley Terminator EFI. I used a completely different light switch for the lighting, and an aftermarket fuse block/wiring harness to power it all. However, my car is a stripped-down street/strip car. The only accessory I have are power windows (no HVAC, etc).
I wish you luck in whatever path you take with the car. You might also be able to get some good info in the Conversions & Hybrids forum.
