1968 Charger Hellcat Swapped PWM Cooling Fan set up!

[Saleh]

Hello everyone,

So this is my first post and I really hope you guys can help me out with my project.

I did a hellcat swap on my 1968 Charger and used the OEM Radiator cooling fan, Also connected PIN #82 to the fan from the ECU but the fan won't work!
Am I missing something here?

Thanks

How is it grounded?

You mean to the ground side of a relay correct?

 

[Jerry Hall]

The way I see it is that pin #82 energies or operates a relay that switches 12V to operate the fan. The fan also has to be grounded.

I did exactly as Goose performance did in his video :

power and ground are connected to the fan as well as a pcm signal from pin 82

There has to be a relay involved, even if it is internal to the fan assembly. The PCM signal will not run the fan.

The PCM should ground a relay.

you updated everything in your tune in HPTuners? Similar to below?

Yes sir, I did

This pinout shows PIN 83 is PWM fan control.

I made a direct wire connection from the wire that is connecting to pin 83 to the fan small wire and still nothing,

What about the possibility the fan doesn't work?

So you're getting the engine hot and it doesn't fire up? The srts started at like 225* F if I'm not mistaken.

Thats why I'm trying to get a new fan and test it again

the factory setting is set at 208F for the fan to kick on

 

[What’s up dock]

So, you've got pin 82 run to the "trigger" side of your relay, pin 83 directly to your white PWM wire on the fan?

I finally figured it out! I moved pin #83 to pin #82 (which was empty in my case) and it finally worked !

I’m about to do the same on my 69 Charger.

Did you end up just using pin #83 to the white wire and power, ground from the fan?
