Sorry partner.... I am not sure what that even is...Not familiar with that...Maybe one of these other people here could steer you in a direction..... What exactly is it?? Willy
Ok.....I read on it a little....Looks like it is the wiring harness to connect your aftermarket HU.....It also allows the door open chime, lights on and other warning things that chime to continue to work....And I guess if you have the delayed power shut down after key off to run the radio, it will allow that function to work....I believe that is the only harness you need to connect your new HU......Apparantly if you wanted to forego the chimes and stuff you could get a standard harness adaptor and power the HU, speakers, etc and lose the chime function..... That is what it looks like to me.... Willy
You NEED the data Bus Adapter. Dont get stupid and cheap, do it right. Also, the data bus adapter supplies you with an ignition wire. You don't have one behind the radio. The factory radio uses a data line, not an ignition line, to know when to turn on and off. Your truck do it any way you want. My 10 cents worth
