Scosche GM2000SWF Factory Stereo Replacement Interface Adapter, Compatible with Select 2000-13 GM Vehicles, Car Radio Wiring Harness, Retains Steering Wheel Controls & OEM Amplifier - See Fit Guide

Half the price of the old kit I use to run. Cheaper and quicker install without looking for a signal. Literally plug and play and my steering wheel controls work perfect.

This harness will work for a 2004 Chevy Trailblazer with the standard Bose system. Mine has the (UQA) RPO but none of the others (Y91/Y92/Z75). All I did was crimp the matching colors together with butt connectors and plugged it all in, worked flawlessly the first time. I did have a few colors left over, one or two from the harness and two or three from the Pioneer headunit I used. I believe they were purple/white, orange/white, and yellow/white and a light green. The dings work as well!

Works great! Perfect part for completing the installation

Fairly easy install good product. I had a bit of a wiring issue and contacted them directly. Withing 12 hrs i had tech support email me everythi g i needed to know. Hooked it with an android tabket head unit. Works great! Stereo is even louder and it even worked for my Bose system! Thanks for the help and the good product!

I have used these before and worked great, this time I got a bad one. Loose wiring in the connection and I keep losing sound

I usually don’t do reviews, but I felt this could help somebody out..I have been struggling trying to get a 10 inch android radio wired for a month. This is the harness you need if you intend to do the same. As a previous reviewer stated it works on the trailblazer without the jumper wire. I bought 2 other harnesses that come with the Jump wire. I tapped into the brown wire on 1 and ran a fuse jumper to the ignition fuse on the other.. neither worked. This one was truly plug and play. Just wire all colors correctly and you will be good to go.

I ordered my husband an Apple car play stereo for his truck and when we started installing we realized we needed this extra plug to make the car play work upon looking on Google they were way to pricy for me so I put the product number in Amazon and this came up so I took a chance and ordered it. It worked perfectly and was half the price. Highly recommend!!!!

Best thing I’ve ever done to this truck. Works great and to answer your question yes this works with your Bose factory system. I got everything wired up to the harness adapter and plugged it up. Works perfect and definitely beats buying that 150$ kit off that one website
