I have a 87 GTA that I recently completed a 5.3L Turbo LS Swap with a Holley Terminator Max kit. Car ran and drove before the swap, and I recently got it running and driving again.

I came home the other day to drive it, and have no power to anything except the courtesy lights. When I turn the ignition, nothing from the body harness but the Holley kit does trigger on, however when I turn the key off the Holley kit remains on until I kill the battery disconnect. Very strange since it was running and driving perfectly up until this point.

I replaced the ignition switch just to be safe, and no change. Every fuse in the fuse block is good, and traced the main power wires to and from the battery to the engine bay and all has 12 volts but nothing at the body harness items.

Any ideas?? Thanks in advance!

 

Since it's not a factory setup, we could only guess at the problem. Only the person that wired it will have the best knowledge of how it was setup
