Thread: Fan wiring question

That seems like it'd be only one speed.
Are you just going to run them on high every time? They might draw so much power that the alternator won't be able to keep up at idle.

In fact, most relays are rated at 30 amps, which is normally just adequate for 1 fan. There's no way you'll run both with just 1, especially if it's on high.

The temp switch I bought is supposedly 2-speed. I'm not sure about the fans as they're OEM. I'm not certain how the two speed temp switch works either. I would have thought that it grounds at a certain temp and that's it.

I'm open to suggestions.

bump I wanna get this done today so I can fire up this bad boy!! Anyone wanna see a built sr20ve with itb's and standalone, please chime in...

It also just occured to my that somewhere along the line I decided to keep the ecu fired up even though I'm doing standalone.

So unless someone has a better suggestion how to do the wiring, Im just going to reconnect the stock 4-wire connections on each fan in the oem harness, and tap back the temp sensor wire on the ecu (pin 18) back from the standalone (which I had cut off before)

I just wired up the blue and black wire. mine work
