That is part of the choke that you are talking about. Netural safety switch is usually on the tranmission. Early cars had only one wire later cars have 3 wires. It is located on the trans behind the shifting lever. Driver side near the rear of the main housing. > > I have searched on my wiring diagram for our 57 Imperial but can find no reference to either a neutral safety switch or vacuum switch. This is the swtich that fits near the carburettor and coil with 2 little tabs to connect wires too. > > Many thanks > > Ken UK ----------------- http://www.imperialclub.com ----------------- This message was sent to you by the Imperial Mailing List.
