i have a 2" body lift. should i move my efans down to be more inline with my motor like i did my clutch fan shroud or should i keep them even on the radiator?
also, does anyone have any information as far as wiring for the ls1 fans? like a diagram or writeup? some of the wires are pretty self explanatory but i wanna be sure on the pcm wire and i was told i don't need to use the ac tap. :think: thanks.

:hmm: good question. I have a 3" BL and plan on efans fairly soon

I don't really think you need to be concerned about the alignment of the fans to the engine since the fans are there for the main purpose of pulling air through the radiator, if anything you might be making a hot spot in the radiator by moving the fans off center.

Bingo. Leave them aligned with the radiator. Clutch fan shrouds get moved for obvious reasons. Fan is attached to the motor, shroud goes up with the body and would come in contact with the fan unless relocated. Efans....no problem, leave with radiator. :shake:

That is a good point. Hmm. Anyone else?

I dunno if you saw this already or not, but it may have some info about your PCM wire problem.

That harness seems different. I should have mentioned its a black bear harness.

Its not just a "good point" its a fact. lol

If you move the fans down its not going to cool like it should.

What about the wiring? Where does the ac tap go?

Have you tried calling black bear to see if they may know? I don't have a manual so i cant look for you. If you have one you should be able to look it up to at least get an idea of what wire to start looking for, then do as the write up suggested and start testing wires to see which one has current with AC on and none with the AC off.......there's your wire.

Leave the fans on the radiator.. There not there to blow air on the motor they are there to cool the radiator

i have them all hooked up. looks and works great so far. still need to hook up the ac wire. i'm gonna contact justin and ask him.

the a/c wire goes on the power wire for the A/C compressor. or at least it did on my harness. apparently you open up the loom behind the alternator and tap into one of the green wires. i was uncomfortable using a scotch lock on such a tiny wire, so i wired mine to a switch that i put in my center console (the switch is just wired to the + on the fuse box). I just flip it on if i need the fans on high. which isn't really that often.
