After bench racing with some friends I have decided to do away with my heavy duty clutch fan and go with an electric fan setup..I have no cooling issues now, I only want to free up some HP and clean things up a bit in the engine bay...I scored a Cutlass top tray and a Lincoln Mark Viii 2 speed fan....I heard these fans are almost a exact fit for our cars....I am not that sharp on electrical issues...What's the best way/ how to hook these up??

Those fans take a LOT of juice when they first kick on. It can be upwards of 70-100amps just to kick it on.

If you have issues with blowing fuses you may have to go to a time delay fuse as mentioned in one of the comments.

I have been running my MarkVIII Fan for 2 years now. Im running an 75 amp Relay. Im running an positive wire only hot with the key on, to the coil. And I brought an 185F on/ 170F off Coolant Temp switch. Using the Coolant Switch as an Ground to the other side of the coil on the relay. I got both the Relay and Coolant Switch from Summit. Me not trusting anything on my car. I installed another relay to turn on when the the 75 amp relay activates. Which turns on an LED that I mount in my 3 gauge Auto-gage cluster. I only used the high side of the fan. Works great. With my clamp on amp meter i got an 130 amps on start up and a 35 amps steady . So it pulls serious juice. I seen ppls buy two of the 35(?) amp relays which are cheaper and smaller but you have to buy two of them and then by able to wire them up in a parallel circuit (Which is what I did on my glow plug setup.) Hope it is clear as mud.

Sorry, I only come home on the weekends. But can access the site from my phone, but It sucks to type on.
Im running a 160F thermostat. My original fan was a 2 speed, which I had it wired on high. But my used fan motor burnt up. And I got an replacement fan motor from Oriellys. Which I guess I ordered the wrong year. Becuz the replacement fan motor that I got was a One speed. So yeah one speed now. (which from my research the single speed is more powerful then the high speed on the 2 speed fan motor. But Ford changed the fan blades to be quieter, so it dont push more air. But in my case I have a 2 speed fan blade on a 1 speed motor, which from my research, but no confirmed. Some serious air movement.)
I didnt want to waste my time and money with low speed and high speed. The high speed runs for an minute and is off. No worries. But I do have an 140 amp alternator (CS144) installed for any charging issues. But I also have 2 1000 CA batteries being mine is a Diesel. So no issues. Which I dont think there will be any.
JBrue, what engine temp do you want to run? With a 160º thermostat the oil won't get up to proper operating temp and if you use a 180º thermostat the fans will be on constantly with a 185º on 170º off switch

So I guess Im killing my engine. With an OEM In tank Radiator Oil Cooler, External Oil Cooler and a 160F Hi-Flo thermostat. Been running this setup for a year or two. Commuting thur Atlanta during the Hot and Cold daily. Probably 20,000 miles on this Setup. Heat out the heater was hot enough too.
During some research most Oil Manf. suggest 212F. I never and will never run my hot rod that hot. 210F is fine in my book for friends cars. But not in my toys. I like mine on the Cool side, maybe it the Drag racer in me.
