yeah thats the same site I did my harness off of as well, and I have ALL of the pink wires running off of a 12v key power source. So I'm thinking that the PCM loosing power upon ingnition makes pretty good sense. I have it set up with the main power wire from the harness goes to the junction block, along with the main truck power wire, then I have a wire run from the RADIO ign plug on the fuse box, that goes to the harness' ign relay that turns on all the pink Keyed 12v. I wonder if that ign wire isnt big enough????? I'm pretty sure that's were I ran my old distributor wire from, it's just been 3 1/2 years since I yarded it out.
