Just what I needed

October 6, 2010

Perfect repair part for what I needed, to un-do the butchery of a semi-skilled installer.

Only issue I had with the harness was to match up the proper wires, not all the color codes are the same from the harness to the Metra jumper.

Solution is to go online and search for the wiring diagram, then label each jumper wire with a small masking tape 'flag' with the color it is supposed to connect with, so you know which wire goes where.

Buy a big box of solderless connectors and crimping pliers, then just take your time and it will work fine.
