I also added a power relay module nnear the the driver driver sidee radiator support that provided two fused 60A circuits, one for battery power and another for ignition power. I used to power the fans, A.C. relay, headlight relays, fuseblock, etc., etc. https://www.waytekwire.com/item/4609...e-Module-60A-/
I went to West Marine and bought something like this for my grounds and positives for fans at the front on the engine bay. I then ran 2 10g wires to feed it. Only issue is its not covered for the positives but haven't had any issues.
