Great wiring harness

Review by Randall Benson from , on 3/5/2020

Just know that the wiring for the wipers and part of the heater wiring is not replaced with this kit. The kit was pretty easy to install and I used a crimper from amazon (pro’s kit 300-005 eclipse tool $29) to crimp the connectors on the harness and it worked very well for most of the connectors. It did have a little problem with the connections that had a couple of wires in the same connector but it did work. There are only a half dozen or so connectors like this that I had to work through. I also used a Neiko 3-in-1 automatic wire stripper $15 from Amazon it made stripping the wire a breeze. Both tools well worth the money.
