electric fan conversion
I know you can buy kits with fan controllers but they are fairly expensive. I can get a fan pretty cheap but was wondering about reliably and automatically controlling it. Does the computer in my truck have an unused output for an electric radiator fan? Anybody have input on when you've done such a conversion?
thanks, jamie |

Yes there is an unused port in the PCM that can be programmed to control fans.

Anybody here use a scangauge 2 http://www.scangauge.com/? I'm getting one soon and I wonder if it can program that unused port?

I just looked at the websiteand it's not a programmer - it just gives you engine info and pulls/clears codes. It doesn't actually do any programming with the PCM

You need to have someone with tuning software like HP Tuners go in and activate Pin 42 (I don't think it's changed on the OBS trucks). You can buy (or make) a harness that will hook up to LS1 fans and the programmer can have them kick on at whatever temperature you want.
