Fits 1995 Chevy Suburban

Used to connect stereo from another make of car to 1995 Chevy Suburban. Used another Metra connector on the other end. Works good.

exactly what i wanted

It does exactly what i wanted it to, if i want i can pull out my new deck and swap it for my old one with out having to redo or change any of the wires, just unplug the new and plug on the old (after proper installation of course)

Don't hack your wire harness! Get this!

This made the install so much easier! This is a must have. Everything is labeled and the instructions/diagrams were very informative. No need to struggle with cutting,crimping,soldering, or heat shrinking in the vehicle. You can do everything comfortably at a table or workbench, then plug and play. Great product!
