The factory 964 clock spring only allow for 3 wires. I used the air bag 2 wire circuit, one for upshift and one for down shift and the last remaining single wire circuit was for the horn but I used that for the ground circuit to the center console wire connection which goes the trans. ecu. I hope that makes sense.

 

Arrowhead, I am having a little difficulty on my installation. Specifically, my Momo 7004 hub does not seem to sit down on top of the clock spring properly. The back side of the hub has several flanges that surround the splined area. Did you have any problem in this regard?

 

Had a car specific works bell paddle shift on a z awhile back.
The small return springs can wear. Mine got sloppy and I spent awhile
Finding replacements. Not sure if they updated the wiring, but had to
Re-wire w better gauge stuff. When it worked it was awesome...
