Hey guys. I have an 02 Durango SLT Plus with the 5.9 liter that had an Infinity system originally installed. I have recently swapped out the OEM head unit for an aftermarket upgrade which accommodates direct connection to the OEM steering wheel controls. The original unit had a single OEM wiring harness and I'm told by the manufacturer that all I need to do is direct wire the SWC lead off the new unit to the factory SWC wire/wires. I simply cannot determine which OEM wire colors these are. The only two wires not connecting to the aftermarket harness are a purple/yellow wire and a white wire. I tried the purple/yellow but no luck. Does anyone know anything about this? Thanks

 

Have a look here. See if that is any help.
