Dual electric fans, FIRE!
This tells us NOTHING. I finally surmised that you are using a "Bosch" relay judging from your terminal numbers, HERE is a Bosh relay layout:
So you should have (fuse holder/ fuse large enough for load, say, 20A for one fan) run to pin 86 and 30.
Run a single wire from 85 in to the switch, ground the other end of the switch
Hook your fan wire to relay terminal 87
DO NOT ground any relay terminals with this hookup
===========================================
ALTERNATELY run the fuse to30, hook the fan to 87
Ground 86, run 85 into the switch, and hook a 12V source to the other side of the switch. THIS ALSO should be fused.
The switch part of the circuit draws very little current. You can "rob" switch power off another circuit in the car.
=============================================
With either scheme, hook nothing to 87A
EDIT Geezus did I ever screw that up the first time around
