electrical blackout woes

This morning I took apart the firewall connector that includes the biggest red wire right off the starter relay (the one with a fusible link) and voila! Once I cleaned both sides of the firewall connector with electrical parts cleaner and a wire brush and pushed it all back together everything was back to normal. I will definitely bypass this connection with a big heavy gauge red wire and do the AMP gauge bypass to boot. Unfortunately the plastic locking clips are both now snapped off so the connector is just hanging there….but I'm thinking it will probably still work fine as long as I bypass the main feed wire. Thanks guys for the helpful tips….once again it comes down to me getting off my butt and trying something instead of whining!
On my retired 73 Sno-Fiter (now a parts rig only) after numerous small fuse box fires and red-neck quick fixes, I gave up on the stock harness and ran a bare bones 4 circuit panel in the glove box…..ignition, heater blower, headlights and taillights. The 72 is registered and road worthy and too clean for me to start butchering (yet)! I do now keep a fire extinguisher in the cab!
