wiring efans

[redtop_sr]

ok so my s14 had altima fans when i got it and its all wired and worked great untill the fan blade broke off and put a hole in my radiator. so i got a new radiator and bought 2 ISIS fans there are only two wires that come from the fans instead of 4 like the altima fans and the plugs are the 4 prong or whatever..so my question is how can i wire the ISIS fans into the the connectors since the plugs are for 4 wires?

2 wires are positive and negative, the 4 wires has high and lo fan setting. use a multimeter to find out which one is power or ground. also some aftermarket efan can be use as a pusher or puller depending on the polarity so watch out

i would pickup a fan controller kit from a local parts store, they make adjustable ones that are very easy to install and would isolate the fans from your factory harness, some aftermarket fans will draw more current than the stock causing the wiring to get hot and melt the rubber insulator and may lead to a short

Depending on which way you wire it up, One is a push and one is a pull. To make a pull usually the blue wire is the posotive. I run my power source from my A/C relay on the terminal that has 12v power only when the car is on. Works great.
