The wiring harness is a bit stiff due to the small number of strands of wire used. The cable itself is an OEM dimension so it can handle the current like an OEM wire harness, it just isn't as flexible. The installation itself was easy. I soldered my connections instead of using the supplied compression fitting. If you're buying this for a 99-04 Grand Cherokee, make it easy on yourself and google how to cut the plastic under the headlight so you don't have to remove the bumper and all to get the job done. I cut mine years ago when the first controller died and had no problems. If this relay holds up like the last one, it will be several years before I have to worry about replacing parts again.
