5.3 ls swap underhood wiring

[YatYas1833]

I've got a 1986 (1984) D30 CUCV. Dropped the 5.3 from a 2004 Tahoe in. I just received my PSI wiring harness to drop in it. I'm curious if anyone else has done the same and how they powered the bulkhead junction block, and where the connected the wires from the standalone at, starter and battery power.

I am working a similar swap. I reused the harness from an 05 Suburban. I would love to see how the PSI harness looks after install. I am very tempted to buy one from them and convert to DBC.

I bought a Painless harness so my power to the distribution block will look much different.
