Re: Dummy Light to Gauge dash swap chaos! Help?

I've read GMC Paul's write-up, and a few million other Q&A's...

My problem is wiring of the alternator and battery to the respective #1 and #12 slots on the loom plug...

1. I have no junction block
2. This truck was in some way converted to an internally regulated alternator when the PO also did an HEI conversion

So where do I get these wires from so that my gauges read properly? Any help would be great!
You can connect one right to the terminal on the alternator. I have a single wire internally regulated alternator, so I put the wire right on the alternator lug.

The junction block is just a spot to connect into the wire that feeds the fuse block. Tap into that wire anywhere (t-tap, quick splice, etc.) and it should work.

I went from the alternator output and the junction block on my truck, and the gauge works fine.
