After swapping wiring from early manual trans model to sport manual trans wiring, same production year. I'm missing VSS sensor on gearbox wiring. From wiring diagrams I see that VSS was connected only on early models.
Questions are:
1. If I leave unconnected sensor what will not work?
2. If I change ECM and all needed modules from the wiring donor car will it work? donor has DCS, but is missing cruise control.
3. Can cruise control be activated via SDD?

Thanks!
