Why would you want a manual switch for your fan. Is the car overheating?

madblkscientist

first how do u want it wired exp-inline with ur cars oem radiator wiring or do u want it to be controlled only by the swicth or did the car have a mechnical fan and u want to put a electric fan

what is the purpose i can draw u a simply diagram

gretna24

no its not overheating when i brought the car the guy told me he was in the processes of wiring the fan to a switch so he cut the harness thing that was connected to the wires on the fan.its a long story

gretna24

i want to be able to turn the fans on and of with a switch in the car.that diagram well be very helpfull

gretna24

whats up with that diagram?

madblkscientist

i just got back on bro hold up

r u not scared of forgeting to turn it on

do u want it with a fuse (best) and relay(optional)

would u rather it b automatic and go on and off via a temp swicth

gretna24

i want it connected to a switch in my car i guess ill take the fuse option sence you are saying its the best and i tested the fan already by connecting the 1 wire from the fan to the postive battery post and the other wire to the negetive and they work

gretna24

naa i wouldnt forget to turn them on hope not lol

madblkscientist

here u go sorry it took so long

madblkscientist

this is the way i would do it

madblkscientist

with that swicth is it a lighted swicth or a led swicth

or a single pole double throw

gretna24

its a lighted switch and thanks man i wish i could give you like $5.00 for your time lol, i really appreciate it bro

gretna24

quick question im looking at option 1 and 2 and are there any wires suppose to be coming out the negative battery post because im looking at your drawing and it looks like a wire is connected to the negative battery post or should i just ignore that

madblkscientist

just ignor that ground one wire from the fan to the chasis that is also ground

imma show u which is whivh i got the swicth here imma write a diagram 4 that also

madblkscientist

use diagram 2 those swicthes arent meant for anything over 5 amps

Why not just remove the plug from the fan thermoswitch (located on the thermostat housing) and run a switch in between the two pins?

The power source is a switched source and the fan won't stay on without the ignition keyed on, and you won't be calling yourself a dumbass for having to buy a new battery. The converse of that however is that you forget to turn it on.....then you're hosed.

Really, the best option is to use the engine control to control the fan's on/off thresholds. That way you don't even have to think about it.

madblkscientist

since he said the wiring is all hacked up he would have to do the temp swicth diagram i put up to put it near oem and just reuse the thermo swicth

madblkscientist

who knows what he tring i just gave him the tools

gretna24

ok i got the fan running like in option 1 (the easy way) it it works fine but now im thinking about sence my ac was puuled out from the previous owner,would it make sence to run another switch to the ac fans and have two running fans

madblkscientist

why all these swicthes

i would have done the temp swicth instead of the swicth

anyways u have a wire in there for the ac to kick on if u can source it

or u can just put a relay and run both fans off the same swicth

madblkscientist

gretna24

well anything that belonged to the ac was removed from the car even the climate controls and the ac lines are gone(from previous owner)
so i figured i will put the ac fan to work instead of just having it sit there lol,but yea i will put them on a relay and run them off the same switch.it seems better to do that. thanks for the help man

look at the diagram up top of his last post he added the extra fan
