This one will handle the current the fan will draw.

Simply reversing polarity does not provide the same air output, it's a combination of blade rotation, maybe it's different with these "s" type blades than straight blades but it certainly makes a huge difference in performance

Any suggestions on a better one, NAPA had nothing nor did Advanced Auto.I was hoping to use something like this and cut it in half but then again, no rating

Now I just want to know if I flipped it in case someone asks. Can someone with this same fan chime in?
I checked my fan blade orientation and your reflipped blade is the same as mine. My fan assembly is opposite from yours (black is hot and blue is ground) but the fan orientation is (the same) correct. I guess your wife's hair is the ultimate test. lol.

Congrats of your fan runon after engine shut off setup. Love it. I might have to copy your setup in the future but not before I add Jim's 20% run all the time module to my wife Nancy's car.

I used a waterproof connector for the fan that I found at Summit Racing. It's rated at 20amps, is kind of expensive but is very cool IMHO. Here's the link:

Edit-BTW being a baker, I really like your cake pan fan mount. Very clean looking and is definitely better than my messy setup. But bottom line is that mine works and that's the way it is going to stay. Again congrats on coming up with that design.

Thanks for checking that out and the compliments.

That connector is exactly what I was looking for at NAPA. In the link you provided, is that a male and female as it doesn't look like it.

I found this one on Amazon, does this look sufficient to hand the current, looks to be the same part?

The Summit part is male and female. Looks very similar to the Amazon connector, maybe the same although different brand name. Amazon does not list a capacity while Summit does but they are so similar that the Amazon connector must be able to carry 20 amps.

I can tell you that these connectors are very OE and went together easily. I soldered the pins onto the wires. Make sure you slide the little rubber seals onto the wires before sliding on the connectors and soldering but, of course, you know that.

Thanks John.

yes, I agree these connectors are very OEM, it's exactly what I had in mind when I first went searching. I was very surprised not to find them at the auto parts store

Yeah! I looked in the autoparts stores too and was amazed that no one carried a weather proof connector. I think it's another bean counter problem-they are too expensive so customers mainly buy cheap spade connectors. Ridiculous!!!!

I got the fan installed today, fits perfect.

Thought I'd first wire up the Derale according to the instructions first to set it properly. Still need to wire up the resistors and relays and button everything up.

Now for the pics :








Good for another 184,000!

Is there an updated parts list for the conversion from anyone or are we sticking with what Valex has done. I need to do this ASAP but I want to grab the latest fan and parts. Let me know.

Thx!
