[QUOTE="d4ngerz0ne, post: 745538, member: 45572"] Can't say this is will be an update with a happy ending . Everything wired up , Constant 12v, ignition on 12v were spot on. Good continuity in the circuit judging from the multimeter. Fan wouldn't turn on at operating temperature (read out from KTEMP) even after adjusting the activiation temperature (dial) . Shorted out the temperature sensor pins as detailed in the instructions to ramp it to high RPM , success ! Fan came on , but at the expense of the controller ( a resistor on the board) has burnt out. fml. Controller is rated for 50 amp , where as fan inrush current only maxes at 22.1 amps. Not sure what I could have done wrong, sigh. I've emailed the guy that makes these controllers (has a 1 year warranty) and hopefully something can be done about it. The fact that i've been collecting parts and planning for the last 6 months and hitting this hurdle is really frustrating ! [/QUOTE]
