I'm with 52 Carl. I picked up my truck this Sept. the wiring was original. Was original ! It took me about 14 hours to put in a new harness, excluding the dome light, that's a a few more hours and in progress since the headlings need to come out and I'm adding a shoulder harness while it apart. I ordered a standard kit for around 150 but added another $150 or or so in new grommets, turn signals,front parking lamp sockets and terminals for headlamps. I also bought the wire harness clips and changed those as necessary
