I have a 2006 Chevy 3/4 ton express van. It has the stock GM AM FM radio in it. I have a 1990 GM AM FM cassette radio that has seen many vehicles over the years. I have rebuilt the cassette mechanism and it is in perfect work ing condition. It is coming out of my 2002 van before that goes to the junk yard. I would like to install that radio in the 2006. I went to the dealer to ask if he could please pull a print of the 2006 wiring harness showing colors, etc, but he said that that information was not available. I know th at when I did this swap into the 2002 years ago I don't recall having any t rouble finding this information. In fact I think that it was at this partic ular dealership that I did. He says that all he could pull up was a picture of the whole harness which doesn't break down to colors of wires. Could it be that he only has access to a "parts" manual and what I'm looking for wo uld be in a separate "service" manual?
What I would like to do is to cut the 2006 connector off the tail end of th e harness and splice the 1990 connector in it's place. I don't care about p ower antenna or chimes etc. I just need the 2006 harness colors for power, standby power for the clock and tuner memory, and front and rear speakers, and ground.
Let me add that if you feel it necessary to tell me how foolish you feel it is to install a 1990 radio into a 2006 vehicle, please don't bother. This is what I would like to do.
If anyone can help me with this I would be most sincerely appreciative. Len ny
