Injector/Glowplug wire harness damage.

Recently found out I have a pretty big injector problem. That's cool. I'm sure they have plenty of miles on them, and I was going to upgrade them anyway. There is also a kit for the reinstall with gaskets and interior wiring. Dope.

But my heart sank when I found this guy. Broken and covered in oil. Wondering if anyone could tell me what my options are. Is it ideal to splice a new connector? Need new wiring?

Thumbs up

Alliant sells that plug, I would have to find who sells it. Price was about $30. One of mine has a cracked retention clip, so I want to replace all four here at some point. There is also a tool to depin the thing. May want to consider the Super Duty single plug if you feel like farting with that. Me? I choose to not reinvent the wheel all the time. I would just fix that OE style and get on with life.

Maybe it was Beans.



Usually when that melts there are other issues that need to be addressed. I recall reading something about the glow plugs drawing too much current? You also may need a new valve cover gasket and under valve cover harnesses. I think I spent about $150 for both gaskets and four under harnesses. Not too much all things considered. May as well do glow plugs if you have to pop covers and have no documentation of them being done ever.

LOL That's why you want to do the SD plugs. They are heavier duty too with stand the GP current.

One of the sponsors here, Riffraff sells the parts to fix it. I went with the SuperDuty upgrade and it was a little bit of a project soldering everything up. Depending on how much wiring experience you have it will be simpler to stay with the stock parts.

Spend the money and get the superduty system. You'll have to solder in the new pigtails, but its a better system. Clay has everything you need at riffraff.

So the price difference is essentially a couple bucks more, and some extra soldering work? What's the harm in keeping the stock obs harnesses?

OBS harness uses smaller connectors

SD style has bigger connector contact area

Dorman SD ones are cheaper but some have had bad luck with them.

If you stick with stock, OEM is important here. Some people have had luck with the autozone ones, but they are built cheap.

The super duty ones are more skookem and will hold up to the load the glow plugs ask for and wont melt out the harnesses which is what causes the OBS ones to fail.

No harm at all, the SuperDuty harness is more reliable, as has been already mentioned. The soldering itself wasn't much of a job, the only issue I had was making sure I was soldering the right wires together, that took some time and patience. Did not want number 3 injector firing when number 5 was supposed to be firing.

And, as has already been mentioned, OEM is the only way to go.

So I'm going to be doing a glow plug replacement on my '96 and replacing the gasket etc been having no start issues and this and the starter are my last two things I believe I have left.

This is my first time doing this and I'll have a buddy whos a mechanic assisting me (gas mechanic but he's been researching like i have learning together) so I don't do anything stupid and mess stuff up. I'd be interested to know how you did finally figure that out so I can be better informed on how to solder the right connections. I like the idea of a better more reliable connection and reduction of issues arising from the glow plugs draw. Any guidance on how to do this will be much appreciated.

Thanks all!

Just what I needed. Another user posted this link, but I can't seem to find them to give credit.

Haven't done the job yet, but injectors are expensive. Go figure.
