There is no such thing as an easy aftermarket wiring harness. The less expensive they are, the more difficult they are to install. Don't buy the cheapest kit you can find!

Plan on reusing your headlight switch connector, your ignition switch connector, your turn signal connector, and your dimmer switch connector. Most aftermarket wiring kits are GM based and won't come with Mopar switch connections.

I've done 3 of them now, all from different suppliers. Still looking for a "good one". Gene
