is there a way to eliminate the 4 fan relays and just connect them to turn on with switch on? people have told me since I have a microtech I dont need the 4 relays but no one I know knows how to do it. is there a write up for it?

 

This probably won't help you, and probably isn't what you want to do.

BUT after my car kept killing the battery because the fans just wouldn't turn off, despite replacing the relays and doing at stock fan mod or whatever, I put a wire into the "testing box" thing on the driver side by the battery. Now I flip a switch and the fans come on full blast. It's rigged, but now I'm putting in a PFC, which hopefully with fix that problem.

 

There is a main power wire in the relay group and is fused for the load, i belive its yellow anyway the micro tech probley has a fan control feature. Use the fan control feature to turn on one relay and operate the fan. My haltech does this and it works well.

 

anyone can back this up

 

You're going to need at least one relay to activate the fans because of the electrical load their motors draw. If you just wire them straight to a switch, the switch will eventually fry itself shut from the arcing that will continually occur.

 

The relays that you remove will be 40/50 amp. I cant help you on the microtech. Sorry.

 

I don't believe there is a fan control on the mircotech. the lt12 I wired did not have any connections for fan control, others may be different.

Kento is right, you will need at least 1 relay. I cnnot remember the colors for the wires going into the fan motors, but the harnesses that plug into them coming from the relays have these colors:
yellow/white = medium speed +
red/yellow = high speed +
black = ground -

if you power both Y/W and R/Y and ground them through B the fans will come on high, or if you just power the Y/W wire the fans will only be on medium. You could wire these to a switch through a relay for manual control. I wired the Y/W wire to a separate relay that is switched by a thermoswitch so medium is activated by a set temp. The R/Y is controlled through another relay and switched by a manual switch inside by the driver.

I know this sounds confusing and the thermoswitch has not been tested to work since the car I wired the microtech for does not drive yet. However, I have tested that this wiring scheme works by just powering these wires from a battery and grounding the appropriate wires.

PM me if you have any questions.
