Wiring Plugs

Post by Action » Sat Feb 11, 2023 5:00 pm

I am looking for info about the round plugs with multiple wires, such as ess plug, fuel pressure plug, a/c pressure switch plugs, engine harness to body harness plug, etc.

Do these plugs disassemble easily? I think i need to squeeze a female metal part on a 2-wire plug.

Yes and no. Some are solder cup, some require insert/extraction tooling, and pin crimpers when pins need replaced. Really depends on the particular plug.

Ok. I have no plans to replace anything yet. I just want to get the female metal end out to squeeze it a bit tighter.

On what plug? Like I said, some may not be removable, like the top of the magic box (at least on my truck it’s solder cup)

I described which plug in the first post. The same plug is also on the 4-speed brake switch, and the trans warning lighy...
It is the little plug at bottom of this pic with two wires going in.

That’s a particular one. It’s an ITT/Cannon “sure seal” series connector. If you’re good a soldering you can solder the pins, if not you’ll need the special crimper, not the same as any other crimp tool in my inventory. I modified a old insertion tool to work with those connectors, but you can fight a properly crimped or soldered pin in with a jeweler’s screwdriver, the insertion tool is expensive too.

Link to Newark, but PEI Genesis, Mouser and Digikey sell them as well. https://www.newark.com/itt-cannon/12018 ... dp/26M5723

Just a note, you need to buy pins separately, and like the packards, they have “male” and “female” connector bodies. I’m pretty sure the link is the one I buy to make electronic speedo harnesses and I’m pretty sure interfaces to the tach pickup on the oil drive.

I just looked up the ITT plugs. They 50-100 matings lifespan. I basically just need a better connection between the male and female pins. The males are split in half. I can either spread the male slightly or just put a dab of conductive grease in the female pin.

They’re total crap plugs, but I’ve been unsuccessful at long term repairs on them.

Yeah. An AMG tech told me the joints get loose easily. I try a simple fix tomorrow and will report back.

FWIW, you can push a thin awl into the center of the male pin. (Yes, the male). It will spread the halves apart enough to make a better connection. The plug feels more firm when pushing back together.
