I just watch Mitch from "Swaptimeusa" go over the wiring again. As I understand the new fuse box that is now on the ECM has a red wire going to the alternator which will have one directly from the battery. so it will be hot all the time. There is another small gauge wire from the new fuse box that goes to the starter. The new pink wire is what I thought should go to what would have been the old distributor wire (purple) which when the key was turned to start would excite the starter solenoid.

Wrote Mitch an email to do a pen drawing???
