MK4 Supra Fan Wiring

[93_Cory_TT]

Hi,

I'm trying to get my 93 TT Supra back on the road, one of the jobs I need to do before this can happen is to wire the fan's to the car.

Currently I have a Koyorad radiator with twin electric Flex-o-Lite fans attached. On the wiring side: both fans are wired to relay (90987-02010), which is wired to a 30A fuse, power to that fuse is from another relay on the car in the fuse box (EFI MAIN). On the second relay (90987-02010), connection 3 is the power in, connection 5 goes to the fan's, 2 is ground but currently I have a cable connected to connection 1 which isn't connected to anything, I believe this is the input signal for the relay to bring the fan's on.

I need to know where would be the best place to connect this cable to, which will bring the fans on if the car detects it's getting hot. I have read on some formus that the fan's can be controlled by the themostat. I currently have a plug which I believe is the ECU control for the water temp sensor (the plug is under the upper radiator hose, this plug has 2 cables on it). I'm hoping it's possible to take the signal to bring the fan's on from this plug, but I wanted to check this before I do it.

I know these fan's are wired wrong at the minute, twin electric fan's should be on seperate circuits, just in case one fan fail's, it will not stop the other from working as well. I think the way the fan's are wired on my car at the minute should work, I want to do this to get them temporarily working because the car needs mapping. The eventual plan is to get the car to SRD Tuning to have them properly wired.

Any advice on how I can get the fan's connected and working would be great, as I can't find a clear answer on how to do this.

Thanks.
