Ignition switch on 27 Buick in Buick - Pre War Posted September 25, 2011 I'm trying to figure out the wiring for my ignition switch on my 27 Buick. The wires were all missing when I got the car. It has an ignition switch with light switch and key lock on the front. On the back it says KELLOGG S&S CO. # 1133. It has 7 terminals. The # 7 terminal is wirerd so no problem, but can't figure out the rest. Thanks for any Help.
