Recently bought a 1993 and its a time capsule since main build was done in 1995 to which is sat untouched since then.

I want to remove the hard start fan relays and get a DCC pwm unit in place.
Currently the car has an aftermarket aluminum radiator and mishimoto dual 12" fans.

edit: I figured out info I needed, S50 is the current pwm controller that replaced the FK45. I have one on order, now I wait for it to deliver. Than I will dig in.

I knew a few others who had them in their 69 stands and never had an issue with them. I had a flexalite controller with the soft start and both times they failed within a year.

Going to order SVE aluminum radiator and contour fan as well. The current alum radiator car came with doesn't fit right and has epoxy end tanks, my luck I get everything done and it starts to leak and I have to do twice.

I still have the original FK-35 with the Contour fans. He's probably still building the controllers one at a time whenever he gets an order. When I changed from the Mark VIII fan to the Contour fans, I bought 2 fan connectors from Rock Auto. I had a heavy duty terminal block in my parts bin. Mounted the FK-35 on the radiator core support for better heatsink cooling. Pic shows it partially removed.

Apparently my ex-husband made that mistake.

I have a PWM out of a Mazda 6 I bought on Amazon for $20. I found the pigtails for it on Amazon for like $8 or something. The Mazda 6 PWM has outputs for 2 fans.
