Dual fan install in L03
I have the dual fan setup off an IROC I want to use on my L03. Has anyone done this? What do I need to do to make it work? Is it as simple as splicing in the other fan wire or is it more complicated? What's the deal?
Thanks

A "real" dual fan setup has separate controls for the 2 fans. They run at different times for different reasons. So you'd need all kinds of wiring and chip programming and whatnot to make it work the same way in the lesser car as it does in the car it came out of.
But there's no reason you couldn't just hook up both of its fan motors to your existing fan wiring.

All I want is for both fans to kick on at the same time. I was thinking I can splice the dual fan wiring into the stock single wiring, but I want to make sure that it won't burn up something else.

use a second relay for the second fan.... they're $6 from the auto parts store.. you can mount it next to the stock one.
just have the relay trigger, trigger the 2nd relay too
