Mopar has used twisted wires on the 2 wire buss circuits as long as I remember working with them. They also had a single wire buss which of course you cant twist but some of the buss circuits work on about 2.5 volts at times and since its a comunication circuit between computers in the car it makes sense to do what they can to eliminate any problems. I had problems on one year of Caravans that used the older CCD buss when the eng electric fan wires ran to close to the buss wires and sometimes the van would cut out when the fan kicked on. That was a tricky one to figure out as I remember working with a Chrysler engineer on that Caravan. Ron
