Worked perfectly!

Totally recommend this product. Harnesses for this vehicle are hard to find and this worked perfectly

Great Help!

recommended for aftermarket installers for dummys, if you can read colors and know your colors, connect wires together; that easy. It really made me look like a genuis.
P:easy install with simple instructions
C:still trying to find one

Excellent, as always...

I always recommend Scosche harnesses when installing after market decks. The connections are always high quality and fit snugly. I have never had any problems with Scosche products..

Quick and Easy

makes installing your head unit a ease without it or any harness you will probably be connecting wires for a half an hour that if you have your interior wires data sheet if not you'll be spending hours trying to discover which speakers they run too. Also, using a voltage tester to find the remote and battery wires...good luck with that.
