black sticky goo in C-100 plug
Hello, I have finished my digital dash swap, and while I had the C-100 plug apart i cleaned this balck sticky goo out of the connector w/ electrical contact cleaner. I figured the connections had to be creating evena mild short. Wel now the A4 red plug is loose, and i need to know if the goo really needs to be in there to "stiffen up" the connections. It may have di-electric 20 years ago, but man this stuff stained everything, and was a mess to wash off. T/Y

That goo was grease to keep the contacts from corroding.

That's the factory's waterproofing and corrosion protection.
If you clean it off and don't replace it with SOMETHING appropriate, you WILL suffer from corrosion problems, and bad connections.
Given that most of the things you can buy commonly to perform a similar function (like No-Ox for example) are kind of runny and not meant for the same purpose, what they used is actually pretty effective and properly chosen.
Yes, it or a suitable substitute, needs to be in there.

Well, i guess i could take it back apart. Anyone have an idea of some good Filler. It would have to be rather dense, as to not run out like syrup. thanks

Grease, just like the factory used.

bearing/axle grease. Isn't that conductive?

Re: black sticky goo in C-100 plug
because it's a liquid/semi solid, and carbon based. I guess i could stick my meter leads into a can of bearing grease and see. LOL

Grease isn't carbon based it's a hydrocarbon, and the state of a material doesn't have much to do with it's conductive properties.

What the factory used isn't grease; it's some sort of tar-like stuff.
Grease would just get all nasty and run out and be gross. I wouldn't even try that.
There's a handful of electrical waterproofing substances on the market for packing connectors. A Google search would probabyl turn up LOTS of potential substitutes.
