Yeah I like being in control of the fan. The Fan controller I got works perfectly but I like to be able to turn it off when I turn the car off rather than letting it run until the car cools down even when the car is off

If wired correctly the fan should not run with ignition off. Or it can if it is temp controlled to do that. But i never wire it that way. What i do is use 2 fans one at 1/2 speed and run it all the time. Then when the AC comes on or the motor heats up a bit the other fan kicks in and if more cooling is needed the 1/2 speed fan comes on full. basically having a switch is bad because you might forget to turn it on or someone borrowing the car might not turn it on. Sometimes we use a dual speed fan from like a taurus and run the low speed constantly and control the high speed with a controller or sender. Several choices. In my opinion a switch is not my cup of tea.

Normally if space allows we use 2 fans all the time. You never know when a fan will fail. And they are wired separately with there own relays and senders for safety.

Here is one of my first setups. We now use aluminum stock to mount the fans. Just an example bellow for a mustang

Tom you get an A for effort but you are loosing alot os surface area with that angle iron try using a ford contour dual fan with a flex a lite speed controler

Proto type the new setup uses aluminum brackets and no restricted air flow. That setup was scrapped. Those fans can move tuns of air believe me i am not kidding.The new setup does not use any vertical braces and allows full fan airflow to the core

I would not wire a mark 8 from the fuse box, as you probably know they can pull 80 amps when they kick on. If you need to for temporary run it off a relay/switch I used a Stinger 80 amp relay for mine.

I was told to run a wire directly to the battery. Mine is relocated in the trunk so would it be ok to run it to the starter solenoid?? Since this runs back to the battery should this be ok instead of running 10 ft of wire through my car to the trunk?? Thanks for all the advice.

edit: I have the tyco relay installed next to the dcc fan controller. I used an inline fuse at the fusebox and it literally burnt the 40amp fuse I had in there. I want to get this fixed asap

Not necessary to run a cable to the trunk. Use the cable from the battery i am assuming it goes to the fender relay is perfectly OK. Personally i would not use a fan that draws that much current, 80 Amps is outrageously high for a fan to draw. The fans i use draw 20 then taper off to 10 while running. using a fan that draws that much current is counter productive. But if it does you need an appropriate circuit to handle the load.

Ok so let me get this straight. I have the fan ran to a dcc fan controller, to the tyco relay, into my dash where I have the switch and run the wire instead of into my fuse box, back into the engine bay and onto the starter solenoid?

I hooked it up according to how I just explained it in the top part. (fan to dcc fan controller, to tyco relay, to switch, to starter solenoid) Seems to be working good and also it draws less amps when it turns on being hooked up to the starter solenoid. I don't know why?? If for some reason you think theres a better way or I'm doing something wrong. And if what I did is correct please let me know, thanks again!

Perfectly fine but i am not a toggle switch fan on guy. But perfect. You most likely have a better voltage drop and the current went down proportionately.

Thanks for all the advice and feedback. I cut it down to fit clearing the water pump pulley. I then put weather stripping around it to make it a tight seal against the radiator. Works great and keeps the car really cool. QUESTION- I have a 190 thermostat, when should I set the fan to come on? I was told to set it to turn on 10-15 degrees after the thermostat opens (200-205), thus letting the thermostat cool it down enough to where the fan might not even need to come on at all. Any suggestions? Thanks again for the help
