Glow plug harness

Replacing the glow plugs in the van last evening I discovered that in a previuos life the boots had crumbled. Are there replacement boots or do we just live with it. I'm afraid to ask about the cost of a new harness. Wondering if they can be machined out of another material that can withstand heat a little better. Just thinking. Open to any thoughts on what I should or could do. Oh, the good news is they all came out without a problem. A mixture of Buru, Champion and Autolite. Just lucky I guess.
Thanks,
Doug

Re: Glow plug harness

look for a jyard in your area and you should find a harness in good condition. that is the cheapest way to get one, i don't know of making it your self.

Re: Glow plug harness

You can solder on some connectors and heat shrink. I think a new harness is about $175. Tim

Re: Glow plug harness

I just took apart the whole wireing harness on my controller recently. there is only one wire that goes to the plugs themselves. its the brown wire coming off the controller. just take the plastic top off the controller, unplug all plugs and take out of the plastic tubing. the wire is just taped the to others to make a bundle. all the plug wire is, is one wire thats split into 4 to go evenly to the plugs. probably 6' of wire and 8 connnecters. about 15$ at the most exspenive place around and 30 minutes of labour. all of mine are just about burnt but i didnt feel like buyin the connectors so i just reused them when i relocated ym controller to the driverside fender.............Gibson

Re: Glow plug harness

Most of us just put heat shrink over the bare metal connector. Ensure the HS is longer than the metal so shorting is not a problem when removed from GP and someone turns on the key.........

Re: Glow plug harness

Replacing the $325.00 (Ford Dealership Cost)Glow Plug wiring harness is generally the result of broken connection caps. A standard home Air Conditioner Compressor replacement (screw-on) electrical replacement terminal lug will also fit a Glow Plug tip and costs about $2.00. These are available at any Heating and Air Conditioning supply house. Admittedly, they have signs that they sell only to Contractors. However, you will probably receive a sympathetic ear from the Counter Person. Skin back the wire to a clean section, attach it to the after market replacement lug, tighten it down and repairs are complete. A little electrical tape for insulation purposes probably wouldn't hurt.

Good Hunting,

Re: Glow plug harness

You can go here and buy a new one pretty cheap, it does have some extra wires but they can be removed by opening the loom.
