tow hook,
Not sure what the felt strips would be for. What size are they? What do they look like? Picture? Did the vendor offer any info on what they are used for?
The tail light to harness connection will be whatever the tail light needs. If you're taillights are ALA then there are connectors that must be attached to the harness. Scroll down this page of my build to see the taillights:
https://www.tapatalk.com/groups/cj3b_bulletin_board/green-gruntt-t4658-s30.htmlIf your taillights are after market, the harness may be secured with screws or spades. Get what ever will connect to your lights.
The shrink wrap could help with moisture as will electrical tape.
The clips for the wiring harness differ depending on where you are securing to the body / frame. The frame clips secure the harness to the inside of the frame rail on the bottom. See Lawrence Wade's:
https://cj3b.info/Owners/WadeDetails.htmlI see both Walck's and KW (more types offered for complete harness) offer clips.

You should also be able to find them with other vendors possibly. If you want used ones, Harry Sheets may have a lot:

That hole up front where the harness goes is a change I need to make on my jeep (I didn't know the harness needed to go through that hole until later).
