I went to the pick'n pull and pulled a nice dash (not like the rat nest I have now) and a dash wiring harness.
~dash is gray vs. burgundy... but I'm redoing most of the interior anyway

question is, when I pulled the harness from the donor, the firewall connection was full of black gue.
I'm assuming that was some sort of dielectric grease.
should I pick up a tub of dielectric and lube it up when I install ... or go dry?
