Yet another altima fan question... - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I'm in the process of wiring in Altima fans on my s13 with an S14 SR. I have the following items:

4 30amp relays: http://www.partsexpress.com/pe/showd...number=330-070

Adjustable dual fan thermostat (as seen on heavythrottle): http://www.srownersclub.com/Merchant...ry_Code=FTHERM

I also have plenty of 12 gauge wire, 2 30amp inline fuses, and crimp connectors. My battery has also been relocated behind the passenger seat.

How exactly should I go about splicing them into the existing wiring/fuses/relays? Some of the other threads I've checked left me a bit confused as to where to splice it in (fuel pump relay?, etc). What pins on the relays should I be using?

Does the altima fans have 2 speeds? Not sure why you have 4 relays.
It would depend on how you want them to work. You want them both on all the time? One on and the other one kicks in at a higher temp?

I used four relays on my altima fan set up. One relay for each fan that activated with the ignition, at low speed, then one for medium speed, and one for high. Yes, THREE speeds although I've never had a problem overheating so I rarely set it past the lowest speed. I gutted under the dash and ran a positive lead from the battery to a fused distributor block, since I new I would be needing a source of power when it came to wiring up my gauges. I mounted my relays under the dash and ran the wires all the way to the fans. It looks really clean.

Yea, the altima fans have 2 speeds. Ideally I'd like one to come on at a higher temp. I'm mostly concerned with just getting them to run without blowing any fuses and whatnot.

I was thinking of a distributor/terminal block for power.. Now I just have to find one for that.
