C3 Firewall Electrical Connector
Was yellow-lining the electrical system of my '81 C3, and when I pulled the firewall connector apart and looked inside, I saw this:
Any thoughts on best way to "de-gunk"? I've heard brake cleaner, Dremel tool - anybody had any luck with anything that looked similar.
Any responses sincerely appreciated!





You can clean it up- but you'll need to coat it with anti-oxidant so it doesn't corrode/oxidize in the future.
If you do clean- you'll wanna make SURE it's good and dry before you put it back together-
Thank you so much for the prompt reply.
Ah, yes, anti-oxidant, didn't think of that, but of course it makes sense. It seems particularly dirty, even with the anti-oxidant, but maybe it's okay to just put it back together.
Thanks again Richard454,

I was leaning towards cleaning this up a bit before putting it back together and will do just that.
WD-40 Contact Cleaner, with a toothbrush, make sure it is completely dry, apply antioxidant paste, put it back together.
It does seem like there should be some type of gasket, but I haven't looked closely enough, but will. There is quite a bit of "road debris" on the outside of this connector as it is largely right behind the left front wheel and up a bit, as I'm sure you all know. If there isn't a gasket, there probably should be one. If there is one, it will get replaced.
Thanks again ALL!
Be careful if you use a solvent like lacquer thinner. It could attack the plastic housing.or weaken it.
