SPAL fan Relay wiring

I got the fan pretty much wired but im looking for the best spot to tie in the igniton wire somewhere?
(on when engine is running)
relay is located next to battery on passenger radiator support.
grounds are hooked up, +12volts hooked to the battery.

Re: SPAL fan Relay wiring

I'd run it to the fuse panel.

Re: SPAL fan Relay wiring

I agree, either the ACC or IGN spades of the fuse panel.

Re: SPAL fan Relay wiring

This thread has a picture of the fuse panel and you can see how someone has tapped off it it to feed some accesories.

Re: SPAL fan Relay wiring

Horn relay has battery power to it all the time, regardless of function.
If you have an automatic, you can remove the clutch rod plate from the firewall and either cut & grommet a hole in the plate or get/make a new plate and do the same.

You can't sqeeze 1 more wire through an existing hole in the firewall? A relay wire is very small.

That's what I did. Drilled a hole in the plate and added a grommet. I've got several things going through there.

Re: SPAL fan Relay wiring

Should the relay actually be on a switched source? I know I have seen factory fans that still cool the rad after the engine is turned off. Or is that just a waste being that the engine is not running anyway?

The relay power goes through a temperature switch and when the temp sw is satisfied, sw opens, fan goes off.
Depends on where temp sw is located. Some OEM's have the temp sw monitoring rad outlet tank coolant temp, HVAC high side pressure, or engine compartment temp.
