Just so you know, All Data schematic shows the fan relays running off of the A/C fan fuse(25amp).
They do not on my '87, mine has a RLY,
5 amp fuse at the top of the fuse panel that runs them, (brown wire.) The coolant temp switch (sensor in the front of the manifold) and/or the A/C high pressure switch, and/or the coolant fan delay relay, runs the high speed relay. Lo relay is run by the ECM and/or the fan delay relay.
I wired my dual Cold Case fans (was on the car) to the stock fan relays.
The guy I got the car from had about 28 feet of wires, 2 relays, and a manual fan switch to run them!
