eRod Fan Harness

I am honestly not up to speed on controller versions, though I presume it to be an E38 - the part number is 19257231. It's the controller that comes with the GM eRod LS3.

They only give you one fan control wire which is a bit odd. I'm hoping someone knows the pinouts and I can actually add a second relay in the fusebox, fix the calibration, and get back dual fan control. The calibration is set up for a single fan, but the calibration can still accept two if you change the values.

Failing that I could run both fans in series the whole time and then in parallel when commanded ON, but that's some relay magic and I'd rather not have them on all of the time, of course. Worst case I just run them as one big fan I guess but I'd really rather not.

Can anyone point me at a reference for pinouts and harness wire color or anything similar?

Many thanks,
Dave
