I have installed an after market stereo on my 2007 tc and I'd like to install the stock stereo in my wife's Buick Century. The problem is the harness. Would I need the generic Toyota wiring harness that can be found on ebay for 98c + shipping? Has anyone tried installing the stock stereo on another car? Thanks

 

yes u need two wiring harnes the factory tc and the after market radio harness for the buick just wire them together

 

ok, still don't get it...what do I plug into the stock stereo?

 

You buy the harness that plugs into the stock stereo. It's gonna be a toyota oem harness, you may be able to find one on ebay somewhere. It's not gonna be just a regular wiring harness you would use for an aftermarket radio. Then you're gonna wire that oem harness to a regular harness adapter for the buick.

 

i'm thinking about doing the same thing but to my brothers toyota matrix. have no clue where to start

 

matrix should fit w.o any mods.

 

depending on what year matrix, (03-04) uses the GM delco Headunit, (05-200 uses the base Toyota unit. If it's the 05-2008 JBL unit (premium unit), then thats another story and too often time results in rewiring the speakers to bypass the jbl amp.

If its the 03-04, you would need the Toyota harness for the stock radio and wire that to a GM harness to plug into the stock harness off the Matrix.

05-08 will be just plug and play.

 

ok u need two harness GENERAL MOTORS 1994-UP - INTO CAR/32 PIN metra 70-2001 that plugs into the harness that in the buick then u will wire that to TOYOTA 1987-UP - INTO OEM RADIO metra 71-1761 and that will plug in to the radio from your scion. So you have to harness wired together now dependeing on the year of the buick that part number should be right

 

x2. same for the 03-04 matrix.

 

Thank you so much, I'm on it
