Your first car upgrades? (Electrical/Mechanical)

Assuming that the fuel system and brakes have gotten up to snuff, my next pet peeve is funky electrical. Old cars that have spent time parked with wet carpets over the years probably have corrosion issues on various electrical components in the interior. Here is a non-mopar project that I put an aftermarket fusebox in. I have disassembled and cleaned headlight/ignition switches with Q-tips, so be it. Here was the starting point, with.....surprise surprise, intermittent loss of power to lights etc.
