Glow plug wires under turbo

[SnowDrift]

Where does this clamp attach?

 

[MrMarty51]

There was a similar clamp bolted to the frame on my truck, holding the two forwards GP wires.

This one holds the two center wires on the passenger side - the stubby ones, as shown in the picture. It seems the only place it could mount is on one of the nuts holding the heat tubes in place but that just puts them closer to the heat. There is a clamp right below them but I think I put it on many moons ago to hold other wires away from the heat, but it hasn't been touched to take the engine out, so I think this one has another home, although I can't find it.

If it wasn't so cold. I'd pull the wheel off my truck and get a picture.

I missed this before, but it turns out I had a photo. Thanks for the help, guys.

Attached to a heat shield bolt/stud ?

 

[Stoney]

That's what I was thinking, it's positioned right where it's going to get hot

 

[jrsavoie]

Yep.

Attached to a heat shield bolt/stud ?

I was looking at mine when changing the starter and was surprised it wasn't fried.

I couldn't remember exactly how it attached but It's in a warm area

That orange wire is special Teflon insulated and can handle the heat no problem.

I always wondered how those held up?

Great to know also. I had concerns.

 

[jrsavoie]

Great to know also. I had concerns.

All these years of running these. Since 1989. I've always been surprised that those little wires were never an issue.
Now I know why.

 

[SnowDrift]

Here's the end result.

 

[3500GMC]

The housings for the female spades that attach to the GPs are a ceramic type material, once agan, to survive the heat.

Are replacements available?

I have a couple that are all but gone on the 1994

Even for being ceramic-ish, #3 and #5 on my 96 were deforming from what I can only guess was heat. But, the terminals were fine. Connectivity was good, Resistance was equal to the others, electricity was still flowing and the glow plugs functioning. In 2013 I replaced the harness with the set up from PTWiring Solutions. Bruce (racedaymechanic) stated he’d sourced a ceramic connector. These have held up but, I’ve only put < 25K on the motor in the last 11 years.

On Edit: I don’t know if he’s still in business or not (his website is down) or just doing ‘on demand’ stuff through other vendors.

On further edit CORRECTION: Cylinders 4 and 6 under the turbo I mean (Smack me in the face with a torque wrench). I’m going back to bed.

Bruce had some health issues.
Sold some stuff and I think he's pretty much retired now

Thanks for the heads up. Had a feeling it was something like that.
