Ignition Switch Bypass for 1993 F150. Help!

So due to a failed ignition cylinder, and subsequently a failed drill out attempt, I've gone to trying to install a toggle switch/push button to bypass the ignition switch.
I have successfully started the car and run individual accessory outlets, but I'm no expert on electronics and am not sure how to or if i can wire them all to one switch. The OEM ignition switch has 4 12V lines running into it, so i'm lead to believe that there is not enough power for the 4 accessory (1 of which i cant identify), 1 proof and 1 ignition bypass (which i also cant figure out what that does) to run on just 1 12V input line. I"m guesssing that if I run more than 1 of these lines into a single 25AMP switch, it'll overamp and burn out.

Also, I am using a 16 Gage wire. Is that appropriate?

Thoughts? Thanks

B awhere there are a number of leads that need to be switched.
Among them are a start lead to the TFI that transfers to a Run lead when crank position goes back to Run.
Charge indicator lead, various power feeds to assorted accessories etc.
It's not a simple power the coil deal.
The starter circuit is also involved to crank the motor.
Take a look at the actual switch assembly and the leads involved to get an idea of all this.
Good luck.

Re: Ignition Switch Bypass for 1993 F150. Help!

here is what i'm working with.
F150 IG Switch.jpg

I currently have have a push button with one battery lead and the lead to the starter (STA).

I have a toggle switch with one battery lead and l1. With the switch to on, the truck starts and runs.

My question is this, with that one 25A switch, can i tie all the accessory leads and l1 lead, while only supplying of a single 12V battery lead? Will that overdraw? Should I install a secondary switch for accessories? Can i Attach more than 1 battery lead to the single switch?

Thanks.

The ignition switch is just that, a multi-contact switch. You might want your run switch to close a relay to power one your auxiliaries and keep the circuits separate. It'd suck to have a faulty radio shut down your truck.
