In fact, if it was my truck I'd replace the blue line with a fresh 12 ga wire in red, add a Packard [locking] connector and run the feed end of the red line from IGN UNFUSED in the fuse block on the cab firewall.
You can get sets of Red ''Batt'' and Grey ''Tach'' connectors, each with a color coded 5'' lead, for prett cheap from Jegs or Summit. They slot right into the HEI cap and have extra tabs to prevent mis-connecting.

You're saying the blue is the power wire? I thought it was power wire in back, tach in the front. After pulling it out from the connector, tried putting it back in and crimping. It actually fired right up, like a dummy I tried the multi meter while running and it died as soon as I grounded it. Started back up, but tried to rev it a tiny bit and it cut out and died. Started back up though. I seem to be causing more problems for myself here. Wiring tends to be out of my wheel house. Unless it's just a bad connection on the batt side.
