Very Satisfied

Product was received as advertised and worked perfectly. Product came with radio mounting kit. Experienced no problems with installation of either.

Makes the job easy!

This harness adapter is color-coded to standard wiring on head units and removes the need to cut into the wires of the OEM harness built into the vehicle. I used covered (to prevent accidental shorts) quick disconnects which makes it easy to plug/unplug the head unit if it ever needs to be removed.
