i tried the same thing today and my battery got drained, so how do you run it from a switch?

beatthisspeed69

my old car used to have it to a switch but i cant remember how it was wired..i thought all u had to do was get the wires from the green plug on the radiator and run them to the battery then run the wires from the batter to a switch but my fan just stays on and the switch doesnt turn it off or on so i must be doing something wrong....does n e one no how to run it to a switch????

c'mon no one noes how to do this or wat

its pretty simple actually. i did it with an old defroster switch, mounts next to the sunroof switch. kinda cool, oem look. even has a lighted power indicator.

find this two wire plug on the back of the engine.

then take the yellow/green wire out. get another wire and strip the end, and stuff it in the yellow/green plug, and plug it back in so the stripped end is stuck in with the terminal. connect that wire to a relay and switch, and then ground the relay/switch. easy! press the switch on, it will ground that yellow/green wire which then switches on the radiator fan relay. best thing is that this does not interrupt the normal fan switch either.

do u have n e pics of wat to do cause im kind of confused about the part wen u take the yellow/green wire out so if u have a write up with pics i will greatly appreciate it

what 12 volt+ can you use

Another way is take the fat plug directly from the radiator fan, it has two wires coming from it. One is positive and one is negative. Ground the negative, and run a long *** wire from the positive inside the car to an on/off switch. Most on/off switches have two terminals on them, the switch acts like a breaker. Connect the wire from the fan to one terminal and the other terminal connect it to any "hot" wire underneath the dash, preferrably one that only gets power when the ignition is on. You can add an inline fuse or relay for peace of mind. That is the "ghetto style" way you can do it. Good luck whichever way you go

ok i hooked it all up and stuff now but wen i turn the switch off the fan doesnt go off it just slows down a lot and u can feel and see the wires get realy realy hot wat can be the problem. why do the wires get hot and y wen i turn the switch off it only slows down and wen i turn it on it goes regular???

Does it matter which way round the wires go on to this plug? I just put the loom back on my b16 and am a little unsure as to whether it matters

you dont need to hook up to any 12V. just ground.

you got some major short issues. read my instructions again.

richboi

would it have the same effect if i spliced the wire instead, cuz my setup isnt reallyu like that....cuz theres no plug that i can pull out, its all incased in rubber

Tyson

remove the rubber boot. youll see it underneath.

youre free to splice, i just dont like cutting any stock harness.

glad you found it tho.

lloydadvance

hey what i normally do is just run the hot wire+ to the positive side of the battery run a toggle switch on the inside of the car for the ground side. so positive to battery and run the ground in the car to a ground like a screw. and run it back to the fan so when you turn the switch on it powers the fan up

richboi

thanks alot man........

Hamstr323

you know if you just tap into one of the wires on the plug leading to the fan it will turn on as soon as you turn the ignition to start so it on all the time

Tyson

leaving the fan on constantly is a good way to burn out a fan motor.

Hamstr323

3 years strait & no problems so I don't know what you are talking about???

damn thats the best pix i've ever seen...thanks tho......i jus did wat...tyson did...it works fyne.........no positive or nuttin needed..

well how do i fix that... i suck at wiring and so i dont no **** about it...i did it the way the other guys said it just by getting a long *** wire running it to the switch inside the car and then grounding it or something like that...so how do i fix the shortage issues
