Ignition switch

[Mellvis]

I bought a new ignition switch for the old truck today. The old switch has three tabs that the rubber boot with wires goes onto and three connectors (4 wires on thes connectors total) that go onto the post with a nut. Me new replacement switch has an extra tab (for a total of four) that is outside of the area that the rubber boot goes on to for the other three tabs. Problem? Don't worry? Is this just so the replacement is more of a universal fit? I'm headed out to install it and see what happens.

That extra tab grounds when you start the truck. It is for the later trucks that have a brake warning light and it is what makes the brake warning light come on when you are starting the truck.
