This may be a very stupid question, but I dont know anything about electrics so here it comes..

I have a factory style fan control, exept jet fan switch (195/185) I want to instal a Jegs Adjustable Temperature Control Switch, but I'm not sure how to. Do I just cut the red wire going to the fan and put this between those wires, and it works?

I dont need to put any fuses anywhere, because I'm using the original red wire??

This unit does away with the Jet switch - don't remove it, just leave it in as a plug

Just wire this in as the directions point out - run a pos from the fusible link center to the controller, and run the pos fan wire to the controller, then ground the neg fan wire anywhere.

This will of course make it so the fan runs always regardless of key on/off UNTIL the temp comes down.

To rig so it only runs with ign on, insert a relay between the fusible link connection and the controller, and connect a hot-in-run to the relay along with a ground - then the fan will only run while ign is on and temp is hot enough.

You won't need any fuse, as it's showing a fuse between the battery and the controller - if it doesn't come with this wire with an inline fuse - splice an inline 30amp fuse between the battery and the controller (unless using the relay, then a fuse is not needed as the relay will act as one and burn itself out under too much load).

This will also remove the need foe your fan relay and associated wiring - but you can (and should) leave it all intact until you know everything works properly).

Thanks!

I want it to run only with ign on. I found a wiring diagram and there already is a relay at the other end of the factory redwire(other end is going to the fan) haha.. so I ground the fan -> cut red wire -> put adjustable fanswitch between those two red wires and thats it

i bought a similar one from classic industries, love it and not difficult at all to hook up
