Ford 7.3l Glow Plug Wiring Harness (1989-1991) F250, F350, F450 Super Duty, F59 International 7.3l Motors. 6.9L/7.3L model engine(s).
Catalog Number: 4P53
From 1989-1991 Ford used this glow plug harness in the F250, F350, F450 super Duty, F59 trucks that had International 7.3L motors. We build this harness as close as possible to the stock harness that Ford supplied with the truck.
The original Harness had a special Ford connector that, by now has burnt up in almost all cases . Replacement connectors are not available anywhere.
We supply a new connector that you will install at your fire wall. This New connector replaces the one on your fire will and is much more appropriate for the electrical loads placed upon it.
Connector directions included and wiring schematic included.
