Best way to ground dualfanshroud?

[s13_whoa]

Hey so i recently picked up a IsIs dual fan shroud for my mishimoto radiator & I havent really dealt with grounding things since the stock fan was a sensor I could just plug in. So i was wondering where and what way would be the best to ground the fan? I heard I could ground it to a switch , the ignition n a couple others. What would be best & more efficient ?

First off, ALWAYS use a relay to control a high amperage load like a fan. I, personally, use one of the stock fan switches from a singlecam to GROUND the RELAY for my fan. I also sometimes wire-in a switch on the dash so I can turn the fan on if I want to. The wiring can get pretty complicated and time-consuming to make it look good, especially with a dual fan setup.

Listen to that guy^ go to pick and pull and swipe a few relays and make the ground be your switch.

Well what I did was get the old E-Fan that comes stock & cut the wire & splice it into the dual fanshroud wires. Both positives to the old wire positive & the two negatives to the wires from the new fan. I used two butt connectors and a wire crimp over both & heat shrinked it. So now I basically plug in the same sensor as i would've have with the stock e-fan. Only thing is the fans turn on when the car reaches to a certain temperature I believe it said from 203-230+ theres a low & high. I think above 230+ is when it turns on high. I checked the info on alldata. Also I took off the clutch fan which i might put back on even tho it does minimal help without the old fanshroud. I might just do a another ground to the brake pedal so whenever im in stop & go traffic my fan turns on when im at a stop

that's not a bad idea, but how would the car know when youre at a complete stop to turn the fans on? wouldn't it just turn on everytime you tapped your brakes without actually coming to a complete stop? and if this is the case, it sounds like you just need it on a switch to where you can manually control when you want it on. it just sounds like a lot of unnecessary work imo. :2c:
