Re: 12v IGN source thats hot during crank?
Check out Jeff's (user name:24/7) thread. Great info in this thread. Here is just one post (copied and pasted) that may help.
Purple ignition wire to trunk solenoid AND S terminal on starter solenoid.
8 ga from trunk solenoid (same lug as battery) to GMPP load center main post.
Batt cable from trunk solenoid ( switched side ) to starter lug.
Alternator 8 ga to GMPP load center main post.
Stock cabin or AAW fuse box to GMPP load center main post.
GMPP fuse box main post acting as junction for main loads.
Purple ignition wire triggers both trunk solenoid and starter solenoid at same time when key turned to start.
Main battery cable to starter only hot when key turned all the way to start.
8ga from trunk solenoid acts as battery feed and charge wire, be sure to use fusible link as it will be hot all the time.
