Rad fan switch
I bought an EF hatch with a b16 swap and the original owner had the rad fan hooked up to a switch next to the steering wheel and i want to hook it back up to the engine. I'm not exactly sure how to do that and every time i google it or look for it in the repair manual i can never find a strait answer. i can post pictures tomorrow.

Re: Rad fan switch
The fan relay should be on the passenger side fender well behind the headlight. There should also be 2 wires running from it to where the fan is. Those are the wires that the fan should be hooked up to.
I imagine there was an issue with the oem relay or fan switch so the previous owner bypassed it.

Re: Rad fan switch
There is a fan switch connecting to the thermostat housing I believe, that should be wired to the fan circuit. If it doesn't turn on on its own, he completely severed the circuit and ran a separate 12v source.
What I did was run a switch but grounded it through the cabin, keeping the original fan switch sensor. Look for that fan switch on the thermostat housing, and re-run wires from that sensor to a constant 12 volt source and ground the other on the fan. That is only if you can't find the original wiring in which case simply disconnect the switch re-connect those.
Good Luck
