I need some techincal help with my Frankencav. I am looking to swich my gauge pod (stock from 1990) to one I got from a 1997 Rally Sport. I have the electronic VSS so that is a non issue, but what I need to know is if anyone out there knows what pins correspond to certain gauges on the wiring clip of the newer pod. I have the wiring diagram from the old pod (hooray haynes book!) but need to know what to do for cross-wiring.

You're going to need a 3rd gen wiring diagram to get that info. I doubt anyone in this forum will have it. Try the 3rd gen forum, or just pick up the Haynes.
