Factory Style bulkhead connector mounts directly in the original location – no modification to firewall is needed!
Most of the connectors come pre-terminated, making for a painless install!
High amperage charge wire is included allowing you to easily run modern alternators. The included Midi fuse protects the system, getting rid of the troublesome fusible links that can leave you stranded with no easy fix!
Dual fuel tank ready! If your Squarebody is a dual tank truck, simply use our included dual tank wiring harness to keep both fuel tanks functioning like the factory intended.
For the few non-preterminated connections, mastic heatshrink is included. This will allow you to make professional and waterproof connections with a clean appearance!
