So basically more info to drive this one into the grave.
Clocksprings are different.
GB5Z-14A664-D w/ heated wheel
GB5Z-14A664-C w/o heated wheel
Lacking the connection for the heater element.
Project officially dead. However, since I have an SHO wheel with the paddle shifters, can I add those? Does anyone have a pinout of Connection C218B by any chance? Trying to understand if there is any wiring differences that wouldn't allow the paddle shifters to work if they were hooked up. Looks like their signal return wires are on pin 4 and 12 of C218B.
What can I say...I like projects.
Eh...i'll just buy a SHO.
