Any way to control engagement of electric clutch on cooling fan?

My trans runs a little hot while towing, around 200. I wish I could have an in cab switch so that I could engage the electric clutch on the cooling fan to pull some extra air past the trans cooler when towing. It would also be nice when idling with A/C on in the Texas summer. Surely it is just a 12v feed or a grounding of a circuit that engages the clutch. If anyone know please help me out.

how about adding the largest electric fan you can find and just leave it on when towing big loads. i did this on my 991/2 and the oem fan never cams on. i removed it before i traded for the 04 but havent re-installed it yet.
