i am looking for a glow plug harness, engine harness, and headlight harness for my 83. Doese anyone know where I might be able to buy them?

 

some ford stealerships have 'em but be ready to bleed cause they are real proud of 'em.

 

Thanks for the info. I will check around. None locally have them.

 

check with a international dealer if you have one around you. i just bought a glowplug harness for $100. the ford dealership wanted $500.

 

The stock engine/glow plug harness has all the engine wires in it.

For headlights, check the following thread.

This is a good deal, I get my power from the positive battery terminal and ran 10 guage wire for all my wiring between the battery terminal and the headlights.
Advance Auto has a heavy duty headlight connector for the old style headlights (three prong) that has larger wire into the plug that I used as well.

Brighter headlights with less power through the headlight switch and bulbs that last longer are the benefit of this upgrade.
