Ahhh... yes yes yes. Please disregard my previous post. Too many projects to think about for the relatively small number of marbles I have to work with.

Wow. Just, wow. I’d like to thank the contributors to this thread that just gave me a crash course on electronic engineering and a paint by numbers electric fan install.
On behalf of the members and stall here at, ummm, oh yeah, stangnet.com you are welcome.
We cannot do this without people like you asking for help and advice on fixing and modifying these cars, enthusiasts like you are very important to this site. Without you we would be just another place to post cat videos and pics of what we had for lunch so keep those questions coming and don't forget to tip your waitress and bartenders.
BTW, you are late with your membership dues

I have been running my fans with two 30amp fuses and 40 amp relays...one high...one low... controlled pull down with ms2. I also have an over ride switch to ground. The 40amp relays I have do have diodes. No issues yet. Maybe i should upgrade
On my multimeter I think they read 17 or 18amps running.

These lessons pull from not just physics, but from the three electricity, electronics, and digital techniques classes I had in HS. Thanks for the update.
@90sickfox where are you getting HD diodes from?

Oh hey... One other thing did come to mind from all of this (the thought that screwed me up in the first place):

Depends on the fan. You could just upgrade to the Bosch motor relays.I have been running my fans with two 30amp fuses and 40 amp relays...one high...one low... controlled pull down with ms2.

His controller quality and operation are second to none. I have the FK-75 on my Contour fans. If he didn't recommend it, you'll need the input filter with the low impedance contour fans. It's just and electrolytic capacitor, and you can get one from your local electronics store if you did't order it. I can find the value if you need it.
