ive got my truck trying to start now,i hot wired it. but the battery is dead now ive got it on the charger.

i am wondering what the difference is between a 3 termanial and 4 terminal ignition switch/lock cylinder. which one do you guys recomend i use?

i am going to try my best at cleaning the termanials on my original one, if i can get it out, but if thats a no go then ill go ahead and order one of the switch/lock cylinder you guys recomend from american classic parts.


thanks
