Just hard wire the rear switches to the relays for the rear regulators, youll lose auto but you aint got that now, so who cares
I probably wont bother with the senders for a while, ill track down and gather the parts though.
Next stop i reckon might be poly bushings in the front, im getting some clunks over low speed bumps. Does anyone do a poly bushing kit for the C43?
I have Solid polys on my C43. IMO Theyre better than OEM but I like the stiffer more responsive ride. It did however increase the amount of road noise transfer to the cabin.
