I put in a conduit of plastic tube. The tail light wires and the trim servo wires come forward from the tail thru this pipe into the floor under the cargo area. Then I put some little zip tie fastners onto the rib with #6 screws. Zip ties are a lot easier than Adel clamps. I did buy the stick on zip tie bases but decided not to trust the glue and just screw them on. Also I just used a nut here instead of a platenut.
