Since several have ask what I am doing for wiring here's what I did. I had Andy (got his name from Brendan at Lt1swap.com) at:
https://lsxharness.com/
rework my factory harness and thin it down.
He also installs this fuse block and Relay Block as part of the deal.
He also wires up the electric fans through the relay block #1 and #2.
Then the wires come back marked with 12+, "Ign on", ground, and etc.
