Wiring relay for electric fan
I installed the imperial 16" fan just as shown in Churnds instructions, the only problem is I cant seem to get the relay wired correctly.
The labels on the relay I have are:
-30
-87
-87a
-85
-86
Now what I need to find out is where the switched power, constant 12V power, ground and the two connections to the thermostat go. That should be all I need correct?
Any help is greatly apreciated!

This is how I wired my Bosch 87 Relay and fan
30 = battery positive
86 = switched positive
85 = ground through thermostat (when grounded activates relay)
87 = Fan positive
hope that helps
