Its kinda there.

But lets do it this way.

There are 5 terminals on a standard Bosch 30/40A relay.

30, 85, 86, 87, and 87a.

This is what needs to go where.

86 - Rem wire from HU

85 - Ground

87 - 12v +/0 (switched) or 12v+

30 - Controlling fans + and Rem on for amps

Then ground everything to same spot. I do recommend a Ground distro block for this. Tie in the fans and amps to it.

My wire colors definately don't match with these configurations, are the configurations interchangeable depending on the applications?

I recommend this method as well... usually the standard wire pin-out for fans/remote...
