Shroud is 609 mm wide x 585 mm tall ( 24x23 inches)

Fan itself is not much smaller.....

So i gave these instructions to a friend to wire up the Vette PWM module. I told him to use pin J3-64 as the signal wire. He says it doesnt work and used J3-49 instead & it worked. What's up? Which pin have you guys used?

J3-49 is correct for E67 PWM fan output control. (assuming you have also changed calibrations for PWM fan control)

Thanks Dave.

Plugged it all in tonight to test, and after a few small bugs, it works! Its cool. No spike in amp draw, fan starts up slow, runs at a lower speed until you t gets hotter then runs faster. Cool.

I'm still looking for the real Bette connector and f anyone finds a source. I just used individual spade connectors.

Scot,

What fans are you using?

Also, does anyone have the dimensions of the C6 fan pn 15819952 ?

Before I started the LS swap I had an LT1 in the car and was using mid 90s impala SS fans. Still using them. I'm using one corvette module to power both fans.

Thank you everyone for posting the relevant information. Looks like I can use a C6 Corvette fan (it already comes with the controller plug), in my Cougar build. The plan is to use the Corvette controller module with the Holley Dominator ECU.

Anyone see any reason why this wouldn't work?

Anyone know if the PWM output #1 (pin A19) on the XFI 2.0 can be used for fan PWM controller input?

I want to add a Maxi fuse to the existing GMPP fuse box for the fans. I need this terminal for 10 or 12 gauge wire:







Anyone know where to get some?

For the sake of keeping this thread updated, the above terminal is found here:
