EWIS anyone ?

I did similar, and didn't even know I was doing EWIS. I removed each bulkhead female (used special release tool, but a thin flat screwdriver can work) and cleaned w/ a thin file and contact cleaner. The male plug terminals were easier to clean once removed (squeeze longitudinally w/ needle-nose). I bought a $17 crimper from Fry's that has similar jaws that curl the new 56 terminal crimps around correctly. It doesn't have the levers of your nicer one, so have to squeeze harder.

My bulkhead terminals carry little current since most actuate relays in a fuse/relay box I installed (see post). I used a 1965 bulkhead in my 64 to get its much better high-amp feed-thrus. It has separate buss-bars for the ALT and BAT wires. I kept my ammeter active, but installed a diode-bypass that starts shunting direct to battery at higher currents, in case I up the alternator for fans and EFI.
