Ended up pulling all power from bulkhead connector for battery cables at the fire wall. That was the most direct power/least amount of wire route. So both the fan + wires, and + wires for the relays ran to there. All with inline fuse holders. 30amp for the fans, and 5amp for the relays.
Relays are grounded to the factory shock tower ground because its right there.
Out put signal from relay goes to there respective fans.
in put signal to relay comes from the High and Low trigger pins on the PCM. From what i understand, the way its triggered should allow the 16" fan to run as the "low speed" and then have the 9" fan kick on at the same time as the 16" for the high.
Originally i had them like this:
with the harness running up the outside of the fender mount area along with the light harness.
but, i am a doofus and didnt think of clearance for hood. So when i was all done i tried to close the hood and it was hitting the relays. Unbolted them and rotated them to fit on the face of the tower. And ditched the extra ground block i dont think ill be needed anyway.
