For the rear harness, I cut a hole in the firewall between the driver foot box and the fuse box. I’ve seen others go into the cockpit just below the 4x4 but I was concerned that it would affect leg/knee space so chose to go through the firewall instead. I’ll add a few more wires into the rear harness for a reverse light (from ign), trunk light (from batt) and 3rd brake lights. My plan is to integrate the sending unit harness through the same firewall opening as the rear harness as well as it would align very well with the engine that way. Remains to be seen.

I routed the rear harness along the top driver side of the transmission tunnel, and up along the bottom of the trunk.



I’m planning on integrating the reverse lights and 3rd brake lights into the roll bars, so I split the harness into 3 legs; left, right and continuing straight towards the rear. I planned to re-route the license plate light wires together with the right leg but the existing wire junction in the RF harness from the tail-lights leg to the license plate was further down the harness. I didn’t want to redo the RF split so just pulled it as far ‘up’ as possible and routed it separately to the passenger rollbar. I’ll pull the wires through the trunk floor just behind the roll-bar leg.







I also shortened the fuel sender and fuel pump legs some, but kept them long enough to be able to leave them connected and still drop the tank all the way to the ground. The Holley pump didn’t have a connector so I used shrink-wrapped spade connectors. I then wrapped the entire rear harness in non-adhesive tape, added clamps as needed and consider the rear harness done.



A question: Has anyone had issues with the rear harness vibrating against the fuel tank?
