7M-GTE Wiring Help
 

So i have my 7mgte 90 supra.
i have grown really tired of a clutch fan and wanted to place an electric fan.
however i got the needed temp sensors and cables but i have nowhere to connect them to.
no sort of accessory plugs or anything! i do have a sound system in it along with
other aftermarket items such as boostcontrol,and a turbo timer but i want to hook this fan up correctly and not have it running constantly draining my battery.

any wiring diagrams or any info on where to connect a electric fan onto my supra will be greatly appreciated :)
