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.

gotta disagree James. Lets say the the solenoid draws 4 amps - no idea if that is even close but just for a number. In the stock setup that 4 amps comes from 30 and goes through a devoted set of contacts and out 50.

Granted in the new setup those contacts are no longer being used.

So he is now picking up power from 15 or somewhere downstream of that. Where does that current come from? From the same 30 along the internal buss, through the switched 12v contacts and out 15. From there through the new switch and on to the solenoid. The problem is that you have now added that 4 amps to whatever else normally goes through the switched power contacts that switch from 30 to 15. Further, if he doesn't pick it up at 15 of the ignition switch, and instead uses the distribution point over at s9 he is going through a '25' wire instead of a '40'. Again a worrysome plan for a conservative guy. Do you see what I'm driving at?
