Glow Plug Wire Harness
Hello all,
This is my first time posting and also first time diesel ownwer. I have a 1987 F-350 6.9L diesel, 5 speed manual trans, single axle.
I went to relace a couple bad glow plugs; when I pulled the plug wires off they pretty much decentigrated/crumbled in my hands. Is this common? Now I'm having a hard time finding a place that carries the glow plug electrical harness. Called Oreileys, they couldn't get it. So, called Ford dealer they could order it but, would cost around $500. Sounds a bit expensive. Any sugestions on other places to order from? Thanks in advance.
Jim

Welcome! Can you just put new ends on the wires that are there? Just cut them back a ways and splice a new piece of wire and spade connector. Just make sure you use the same gauge wire because the current these draw. Otherwise you could find a used one I guess. You better grab a tub of Vaseline if you are going to go to the dealer.

You could make your own. Not that hard or expensive. Just time to complete it. Radio shack for wire and connectors. Re-use the controller plugs, or get ring terminals. Just keep track of your wire colors.....

Well just make sure it fits the glow plug of course. Just have them bring a new glow plug out and find the spade that fits it.
This is what I would do...
Get the spades and the right gauge wire. Then solder the spades to the wire. Then slip a piece of heat shrink tube over the solder connection and shrink it with heat. Now you will have a so called pig tail. Just make 8 of them and cut the harness back until you have good wire then solder the connection or crimp it with a butt connector.
They also have butt connectors that have heat shrink tube on them already.
You don't have to solder it if you don't want to. I just would if it was me as an extra measure for good connection and so it won't come apart from vibrations or anything.
hope this helps.

The 87 should have the bullet connectors, not the spade connectors on the glow plug end, if I remember right.

Ive got an 87 with the bullet style connectors. I too had ALL of my nice little connector covers shatter into millions of pieces...well actually they turned into dust. i pulled one GP out and took it to radio shack. just figure out what will fit and grab eight. well 9 if you cant hold on to stuff and you hear it fall to the ground and cant find it. hmmm sounds familiar. then cut and splice and your set.

That and some members have used a bullet connector with good results as well.
Can't remember what size they used though.
I have to wonder what Ford gave you a price for.
I bought a 93 engine wiring harness for 150 dollars 4 or 5 years ago.
If you have the new style glow plug system, that is the same harness you would need.

Ford has discontinued the GP harness, at least for my truck. That's what brought me here so lemonade from lemons. Someone here recommended the replacement bullets. They are NAPA #784353. I've cut the wire at the OEM connector then crimped and soldered the new bullet. Before connecting the bullet I slid a piece of shrink tube and the bullet insulator on the wire then slid it up and heated. It'll work fine my only reservation is whether the nylon cover for the bullet will hold up. Time will tell...
