AMSAMOTION Aftermarket Stereo Radio Wiring Harness Connector Adapter for GM Chevy Silverado GMC 2002-2008 Model

Bought this for a 2006 Chevy Trailblazer that I bought last year which had a the worse electrical wiring work done on it in a horrible after market radio install, which came with the SUV when I bought it. Be warned, this WILL NOT fit right into OEM radio harness to aftermarket radio harness, if those are your intentions. The OEM radio splits into two wiring relays, and this seems to be a huge ongoing problem for anyone installing aftermarket radios on these vehicles. There are a lot of tutorials on how to go about this online, but not one single golden standard way of doing it. But that's all the Vehicle's issue, nothing to do with this harness, so here is my review on it: I like that it comes with the extra red current wire, as it is helpful to run an alternative current source for the 12v accessory port to the radio, it's long enough to run it to an alternative current source by itself - which seems to be rule of thumb when using aftermarket radios on these vehicles. The plastic relay end of the harness seems a bit flimsy, not of high quality but ok quality, for the price, I can't complaint. There wiring colors will not match your vehicle's wire colors, something to keep in mind but expected. The one thing that I really did not like was that the slots for the pins may not house the pins firmly after you remove them and re insert them. Yes, I was very careful and used a pining tool, the pins were not bent or otherwise squeezed in the process, I even tried new pins in the slots at question, and all become unstable after removing the pins the first time. Still, no biggie, you end up having a few open slots if you only use and keep the necessary wires in this harness, I just swapped some spots, no biggie.
