I've decided to bypass ignition switch to save the headache of replacing ignition switch, cylinder, housing, etc and what else maybe causing no resistance to key turning on 82 300D - everything lights up but no final ignition. What's the best way to install PB switch? One wire from switch directly to battery - battery to silenoid, silenoid to switch? Wire size requirement? Whats best place to access inside of car - or drill? Thanks for any advice.
