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.

In our experience, glow plug problems typically are caused, at least in part, by a failure in this harness. OEM part number 1807648C94.  This is the original style glow plug harness for the 7.3L International engine as used in International trucks. This harness should fit early trucks that have the glow plug relay mounted on the rear of the intake manifold. THIS WILL NOT FIT A Ford truck with an International engine.  Made in the USA.  

Because there have been some cases where this does not fit, the best thing to do is to remove your harness, take a good picture of it and e-mail it to us before you purchase it, so we can be 100% certain that it is exact. 

The harness is built using the most common configuration. We have provided a detailed top of engine photograph so that you can compare it to your specific engine.
