HI...
Sounds like you got it much too hot if you are smelling burning.
5 minutes at one inch distance sounds like 10 times too much to me.

you can 'save' this though ( do test-pull on the wires ....and do
continuity check, since the junction has been kinda stressed I suggest ) ..
if they're good, get some Liquid Electrical Tape ..
it's brush-on vynyl in a can ..
works just great, comes in black or red.
I couldn't modify vanagon without this stuff, very useful it is.

the best butt connectectors I've found are marine ones, suppossed to be
waterproof..and have shrink ends.

I used my daughters hair-dryer on the highest heat setting about one inch away for 5 minutes until I could smell burning. The center part shrank but the ends, where the shrinkage is really needed did not shrink at all. So both ends are now open to moisture. Anyone have a clue? This replacement of the 9004 socket is turning into a major project.
