Does anyone know if the OEM control module for the Taurus can be used for the e-fan mod? I would love to do this mod but do not wish to spent $165 for the spal and also do not wish to control it with the rheostat style of controller. Any thoughts here?

Id think the taurus module would work with the pcm and not compatible with the ranger. I just installed a temp switch in line with the radiator hose and using dual 80A relays....hasnt failed me in almost a year

 

Eddie, I think you're right but was wondering if anyone had messed with it. I think that I will do the same thing as what you have done. I was just looking at temp switches at: http://www.indexsensors.com/pdfs/hd_temp_sw_cp.pdf. Something that I was thinking is to use two temp switches; one for the low setting and one for the high setting, just for those extra special moments while towing in the summer or what ever. Low switch setting maybe 205 and high setting maybe 215. Does this sound like overkill? It should be easy enough to implement. The fans high side would be activated by the A/C or the high side switch. I haven't seen that anyone else has done it this way.

Im running an index temp switch....good stuff. I think mines set at 210 and it controls the low speed...high is controlled manually. You can have a custom switch made with 2 different settings...Ive never had to use the high speed to cool it down though...low speed has been enough even in 110+ heat idling or going up a 6% grade, but was empty. I havent gotten around to installing an AC switch so if Im idling, I flip it to high and Im good. Ive got my wiring diagram somewhere...if youd like I can post it up...just gotta find it.

 

Thanks Eddie, I found a good diagram at: https://www.ranger-forums.com/f59/ho...-2speed-69085/. If yours is different, then by all means, lets check it out.

 

heres my diagram...not shown is an LED I added

 

Looks good, I like the discharge diode, I hadn't thought of that. Something else that I was thinking is to tie the "off" switch position to a red led and maybe to the door chime; to help prevent human error. I guess to make that happen I would have to use a "on-on-on" switch.

 

Another thought I've had is to use the red LED for signaling it the fan has malfunctioned or if it should be running and is not. Maybe I'm wanting too many safety devices but why not have them.

 

you're over-thinking it...your wiring is gonna be so complicated and you'll have more stuff that can fail.
