Installed Pusher Electric Fans on a 92 Intercooled Cummins
Decided to put some fans on the front of the condenser. Idk if anyone has done this yet. I found Jim's thread for his non intercooled (aka lots of room) setup; but haven't seen an intercooled setup. This setup required only minor modification to the bottom tabs on the top two grille inserts, where I cut them off. I used two 10" slim fans from mishimoto that are rated for 950 cfm each. To start, take the grille off; though be gentle with it since they don't make em anymore with DODGE lettering. Also I ran all my wiring above the fans, but it might look better to run it below where it will be completely out of site.
After I got the grill off, here you can see the two bottom tabs I cut off on the top grill inserts. You will also have to cut the corresponding grill screw holes that go to those two tabs.
These fans are made as either a pusher or a puller, and they come set up as a puller. In order to make them a pusher, you take the blade off, flip it around, and reverse the wiring. Black is now positive and blue goes to ground.
Here is the relay I used, I mounted it on the back of the headlight screw. I bought the fan relay off amazon and came with instructions on how to wire it. Orange goes to the positive side of fan, red to battery, yellow to a switch in the cab, green to the ac override, and of course black to ground.
Here I found my ac clutch wires bare and almost broken in half (surprised they weren't touching and shorting out). So I decided to splice in my green ac override wire here, which is spliced into the positive side. Mine was the brown wire going to the ac clutch.
Right now the grille is holding the fans in place snuggly to where they won't move nor damage the ac condenser fins. I haven't decided if I want to put brackets in there or use the fan kit that fastens the fans to the radiator, through the fins. The condenser fins might be too tight of a fit to use that kit. The fans though, have not moved since I put them on.
Here is the final product, all put back together, with only those two clips modified. This is my first post and I apologize if there is already a thread of someone doing this, though I could not find one.<br/><br/>Here is the fans and relay I used<br/>http://www.mishimoto.com/mishimoto-slim-line-electric-radiator-fan-10.html<br/><br/>http://www.amazon.com/Derale-16763-Electric-Relay-Harness/dp/B004XONWU4/ref=sr_1_2?ie=UTF8&qid=1463629061&sr=8-2&keywords=fan+relay<br/><br/>If you have any suggestions let me know.

Nice.
I had a problem with excessive A/C head pressure at idle a several years ago. After all the typical culprits were ruled out I dropped a 10" electric fan behind the grille. No cutting required with an offset single.
I powered mine with a relay too. It is mounted near and actuated by the compressor relay.

I put those two same fans on my 92. I also put in a new style replacement condenser, what a difference in a/c performance idling in traffic. I used the mounting kit for the fans but ran the ties through the back of the condenser so there wouldn't be any nibs sticking out to rub on the radiator.
