Bulkhead connector

I didn't.
Of the 3 bulkhead fittings that plug in at the fire wall, I actually ended up buying a new harness for one (the ignition/temp/oil/etc one), a used harness for the other (the wiper motor one).

I could not use the old ones for the one that was melted, as they are not interchangeable.

Since the "Z" connection is actually the power going to the dash, and I got rid of the ammeter, I eliminated the connection at the bulkhead and just ran a new wire right through where it was burned out to the dash.

Either check ebag, which is where I found that pic, post an add here, someone should have one, or if yours is like mine and was only burnt out where the power wire is, eliminate the connection there and just drill out the hole for a new wire.
