2000 dodge ram 250 automatic 30000 miles.
6 years ago I installed a hidden toggle switch in the ignition circuit; anti-theft device; you toggle the switch before turning the key.
Switch broke in the off position so I used pliers to jump across the toggle terminals while cranking.
Engine started but brake warning light wont go out; ABS light wont go out and the speedometer stopped working.
What have I done and how do I fix it?
Brakes are great; engine runs great.
