I am only going to use one fan (Black Magic 3300 cfm) on my conversion. How should I hook up the fan to the computer? Should I use the wiring for fan #1, or #2, or combine them?
Thanks

 

use one of them. this is a gnd. sig. you need to go to a relay. you need it to be programed in the PCM.

 

When I get my PCU programmed I'm going to have both fan controls set for the same temp as a just in case. Nothing wrong with having a spare.

 

Check out a recent Ford Taurus fan. I use it on my LS1 powered Z and it cools it really well. You can get those fans at your local JY for the 25 to 50 dollar mark. If you go that route you will need a 60 amp fuse, a 75 amp relay, and a power line that runs from the alt to the fan. Set the computer up for a single fan and your in business. PM me if your intrested in details.
