I havent double checked your other wiring, but I believe your asking for a place to connect to a switched 12v source. There may be a much better way, but in the past I have run my switched power out of the fuse box using a jumper or a "add a fuse" jumper. Below is Summit's version.

For your 12 volt soure: Fuse 11 (radio) should be switched on/off with the ignition.

Heres a fuse box diagram if you need it

i belive it is a green wire on the rad overflow tank cap that i used for switching a relay.

MSD wiring:

Instead of using the battery negative terminal, attach the heavy gauge black wire to the body ground point by the windshield washer filler.

The battery common ground is a 10 gauge pigtail with the computer ground attached to it.

The ground on the starter solenoid is where the solenoid mounts to the inner fender. I was wondering where he placed his ground from his first post.

This is a troubleshooting problem and not an ECM tuning problem.
