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!!!

The solenoid current is going through the ignition switch contacts in the stock setup, too. No difference there. Indeed, you're stressing the switch slightly less because you're running the solenoid current through a separate switch, but no more current is going through the ignition contacts than go through them if you use the stock starter switch.

If you wire the starter button to the big red battery wire instead of the switched power line, then you're bypassing the ignition switch entirely, stressing it even less, and running 100% of the solenoid current through the starter button only. IMHO, the relay at the solenoid is complete overkill. The 5A or so the solenoid draws is well within the range of most switches, you just don't want to use a milliamp rated microswitch.
