sr20det overheating issues PLEASE HELP

[Mista Sparkoh]

Ok, I had the car for over a year now and I've had overheating issues whenever the temperature rises.My setup consists of a stock SR rad with FAL dual profile electric fans which is connected the the FAL temp sensor to regulate when the fan should be turned on. Now, people have said the stock SR rad shouldn't overheat even after pushing on the highway, but I find that my temp gauge goes way up after cruising the HWY. Even with the e-fan activated, the temp needle won't go down, it only keeps moving up until I have to pull over and turn off the car to let it cool. I didn't install the engine myself so there are some connections still unplugged like this one:\that red harness has a set of wires connected to the temp sensor ONLY. I want to know what it's for and where I can find the other harness to connect it to.I noticed that last nite when it was cooler, the same thing happened, I drove the HWY, got off and the temp needle was creeping up but the e-fan didn't kick in, I checked the fuses, but they're all intactedso now I"m screwed and I need to fix it fast and properI looked at the sr20det manual and found that the clutch fan is activated when the temperature reaches to a certain point, what I like to know is what device triggers the clutch fan to activate?Here are some pictures of my setup...any suggestions on improving my cooling setup would be much appreciatedwhat I really want is to wire my e-fans back to the stock connection so that the engine can regulate the fan activationLooked under the hood but I'm more confused....I'll take pictures of what's not plugged in the car

is there a temp sensor somewhere in the engine that I can plug my FAL fans into?

the clutch fan uses a heat sinc within the clutch to automaticly activate, have you tried replacing your temp gauge sender, when I got my motor installed normal running time was at the top of the temp gauge.

nope I have not...maybe I should do thatso I took out the thermostat and pulled a couple of boosted runs and now everything seems finethe needle is hovering between the 2nd and 3rd notch and looks like it's stablethe e-fan is functioning again and operates periodically so I guess it's the thermostat....I appreciate your help guys
