Installing starter button, Which red wire is power? Options

[jgara962]

Installing a starter buttong inside the car, but there are three red wires coming out of the ignition connector - which is the hot feed that gets connected to the other spade terminal?

From the wiring diagram

15 - which also has a black wire coming out of the same terminal, both going to the fuse panel
30 - goes back to the starter
X - on the diagram it goes to a square with the number 49 in it (I have no idea what that stands for)

I already have the yellow wire from the solenoid connected and thought the power would be X, but I think I guessed wrong.

Thanks!!!

I agree with James. Wiring diagram shows the battery supply to 30 as a big red. Biggest wire going in - same size as the yellow.

Speaking of size. The solenoid is pretty heavy draw. With moving the power to the switched sources you are going to be adding to the draw across the contacts of that part of the switch. Normally the starter is going through dedicated contacts. I have no idea whether the ignition switch will be happy with that extra load. I'm real conservative so I would want to combine this project with putting a relay across the starter. There was a good thread back a few weeks ago.
