Ok so the short story is.. I have a 1987 IROC-Z 305 TPI and the radiator fans are not working whatsoever. I bought the car and the owner said the previous owner before him tried to hook up a toggle switch but never finished. So with that said, I am going to hook up the toggle switch because these cars run hot anyways.. So is what I need to know is.


I have two radiator power relays near my battery. It appears there is a relay for each fan. (I have dual fans).

They basically look JUST like this.. actually they ARE this. I replaced both relays because one was halfway melted.

Now.. I am not the best at electrical wiring..so I looked around on this site and found several topics where wiring a toggle switch was mentioned. However, in all of the topics I found they were all using the Bosch style relay, which in turn looks like this:

These relays are labeled 30, 87, 87a, etc. I see no labeling on the relay that I linked first so I am unsure of which wire goes into which slot. Does it matter? There are 4 points and 1 empty one in it with no markings on the relay itself. So, that is my question.. after I know that I should have no issue wiring the toggle.

OH and also, can anyone tell me where I can find another harness that fits that relay? I have a halfway melted/corroded one and I couldn't find any at the auto store.

 

pic of the actual set up in the car would be helpful. basically if you wanna do a little wiring, you can just get a couple of spdt relays with pigtails from the auto parts store for $5 each, and wire them in to both work like stock and wire in a toggle switch override.
