Review on ACDelco GM OEM D1405B Ignition Switch by Roberto Garrido

Added fuel injection to my second generation Trans Am. The switch for the old parts store worked in all positions, but produced an intermittent 12 volt signal, which was enough to keep the FI computer restarting. The old switch was universal, but this one is designed specifically for models with a rotating wheel. Replaced the old switch with this Delco switch and the problem was solved.
