fan delete pin

im doing the mechanical fan delete on my wagon and need the pin for the cpu,my local dealer wants me to buy 5 at 3.89 each is this common or are they sold individually?

you could also take a pin out of junkyard does not matter which one then splice into the wire. or maybe contact gary at Innovative Wiring

I've found a bag of pins at NAPA in the past. Couldn't buy just one pin


If you only have one pin and screw it up, you'll be thankful for a few spares.

Dave is correct!

I bought mine at the dealer; then later I saw them at NAPA on the rack with odds and ends.

any part # on the aftermarket pin i need?

Exactly what is the PIN and where does it go please?I have the electric fans,upper shroud and the
upper and lower brackets sitting in the garage and should go ahead and install them.

the pin ties the fan to the cpu to turn it on automatically.

Here's the gist of the whole problem.

If you don't have the electrical fans as a stock item you need to replicate all the wiring that needs to be there. That include fuses, relays, wires and connectors to the all points necessary including back to the ECM.

The ECM has a couple of connectors there all ready. Every wire going to it ends in a male / female combination. Since GM didn't put the proper pin there in the connector, you need to do it.

Because I'm running a 7730 ECM for a TPI setup, I use a totally different ECM than the rest of you guy, so I can't help you as to which pin in which connector, but here's an idea that I came up with for swap overs.

Personally, I don't want to commit to the mechanical part of the install until I know I've got the electrical part done correctly. I might screw it up, and now there's ZERO fans!

The fan is simple a load in the circuit. We can substitute a test load instead. If we hook up a 12 light bulb instead of the fan, we have a visual indication that the circuit came on. If we have dual fans at different temps, then we use two bulbs. It's simple enough the lay the bulbs on the cowl, or if you already have a 12 test bulb just use jumpers.

Simple solution.

Now and know you don't have to worry dismantling the mechanical fan only to find out TOO LATE that the electric fan is f**ked up and the freaking engine (or even the regular engine) is overheating.

Instead, we can warm up the engine with the bulbs attached, and Bingo, we have proof that the circuit works.

I hope this helps someone out there!

Dave I agree with you completely and wont do the mod until I know everything is correct.Do you
mean a number 12 lightbulb or a 12volt bulb?I know that sounds silly but I am just being cautious.
Wiring up a battery or a alternator is about my limit of knowledge.
Thanks Again
