Electric Fan power connection

[Hale Ranger]

I just pulled the ECM & wiring harness and have almost completed the DSII conversion.

Need to find a power source for the radiator electric fan. It was connected to the wiring harness I removed. Also have power outlet (cigarette light socket) which needs a power source as well.

Is there a source on the heater/fan assembly?

Are you talking about the heater blower motor? Or have you done an electric cooling fan conversion for the engine? Your question is a bit vague and confusing.

I am hooking up the radiator cooling fan. Sorry about the oops!

1984 would have had a mechanical cooling fan. So, you will have to create your own supply for it. If you know how many amps the fan draws, plan for that size circuit + 25%. For example, if the fan draws 16 amps, design a 20amp circuit. Most of the ones I have messed with need at least a 30amp curcuit. That means a 30 amp fuse and 10awg wire, though because it's a short distance, 12awg will probably work. I strongly recommend 10awg. You will also need a thermostatic switch to control turning it on and off. You can buy kits that have a temperature sensor and controller/relay all in the kit. The sensor usually sticks in the fins of the radiator. There are better ways. Some are outlined in articles in our tech library here on this site. You can connect the ground side at the grounding point on the radiator support over near the driver side headlight.

Post Duraspark swap you have a ton of brand new real estate on you passenger inner fender that very few other Rangers can have. IDEAL territory to run a wire off the starter solenoid to a fuse panel and go to town.

Me being me, I have a fuse panel over there that is constantly hot with the battery. Then I ran what is supposed to go to my ignition around the front of the radiator support (for cleanliness) to run a second fuse panel that is key power via a relay. From there one can really go nuts adding things.

I have my ignition and choke getting its power from the key power fuse panel.

I am working on updating my schematic as I have changed some things but this is what I have:
