Crutchfield Customer Review (What's this?)
I deviated a bit from the included instructions and soldered each connection to the new radio harness, covering each solder joint with a short piece of heat shrink tubing, then covered the entire harness with a larger piece of heat shrink tubing. Of course, those were placed on the wires and moved to one end before I soldered. There's something about mechanical crimp connections that bother me, even among similar metals. Given the temperature and humidity extremes that cars experience in my part of the country, I don't want to make my connections the source of any galvanic corrosion. The wire color codes matched my new receiver's harness exactly, so that made connection a breeze. The most important thing is that it plugged directly into the car's connectors. Nice and easy!
Pros: No splicing of the car's original harness.
