I have 2009 dodge grand caravan c/v. I would like to know if anybody knows if I can change the wire harness inside van.because mines is limited to some opitons like power seat and others. changing van to passenger van I have every thing like seats and seat belts. will I need to change any of the computers because my fuse box has everything listed like power Windows, seats rear ac but does not have it.I took a harness out of a 2009 grand caravan sxt even the dash harness I have. I notice on the c/v harness it the same as other harness but the c/v has some wires missing but plugs are all the same.
