I'm trying to locate it so I can connect the ECU without having to pull the harness (it's routed behind my radio), and see the location of it will help me figure out how to attack it
anyone have a picture of the hydrofan ecu connection on the engine harness?

no problem at all Jay 
. Yesterday was a fun ride home, a lot more torque than I expected. I'll get it sorted out, no worries

Yes, because it's part of the 1JZ engine harness, not the MA70 body harness
Ok so I'm still pretty confused as far as where the hydrofan ecu is supposed to clip in. I do not see any connection on the existing 1JZ harness, though I can find mulitple locations (2) in the car where the connector will clip in, I know neither of them is correct (see below, hah!)
Any help would be greatly appreciated, and if you can, please be very specific, ( little details help me a bunch!!) thanks!

My 1JZ came with the HydroFan, no HydroFan ECU. I mounted the ECU/Controller above and in front of the lateral support bar with the inputs from the radiator Temp. Sensor and outputs to the HydroFan pump. The other inputs I picked up from patching from Main ECU/Body Connectors. I'm still working out some 'kinks' in the wiring overall, but I haven't noticed that the HydroFan ECU/Controller exerts very much control over its pump. Bottom line, until I finish the wiring,... I like the concept and operation of the HydroFan, but the Controller is questionable.
ok so I finally found it. The connection is on the original ECU harness. Seeing as how my harness enters the car on the driver's side thru a new hole I made, I've put the ECU under the stock radio location. With all of the connectors jammed in there it was hiding the hydrofan ECU connection.
