For some reason or another, the stock fan hookup will not work. I don't want to bring it in for the recall because it will still come on at the stock temps (which are too high for my tastes).

Do they make engine temperature sensors for our cars which will turn low speed on at a certain preset temp, and than highspeed at a certain temp? Right now I have direct control over the fan and its becoming a PITA. I want to take the fan off of my mind so I can focus on other things.

So you want to bypass the CCRM, not necessarily the EEC :).

I'm sure it'd be fairly trivial to use the EEC trigger to control your own relay box. I believe the high speed fan uses a ground trigger while the low speed fan uses a positive trigger.

For a simpler solution you could get a stand-alone fan controller that would need another coolant temp sensor to trigger it. These can get as cheap or as complicated as you want. You can get these as Summit / Autozone / Pepboys / whatever.

That's what I'd ask for.

Here is an article quoting a part number and all:

I believe Hayden makes a 2-speed model too.

It looks like it'll be a good idea to upgrade the relay too. The fan pulls 100+ amps starting up and people claim it pulls 40A running but mine never popped the 40A fuse on my '92.

Here is another article of interest:

I have mine running off of a 2 way switch and 2 relays.
Up is for Highspeed
Middle is for Fan Off
Down is for Low Speed.

Very easy to wire up and I have total control. CCRM is not involved at all.
