Robert M posted:I wanted a better quality ignition for my car and bought the sixty dollar-ish Bosch ignition from Sierra Madre Collection. I didn’t realize it is supposed to be paired with an independent starter button. Instead of returning it I plan to pair it with a starter button.
Two questions: 1) Which starter button is other people using? 2) Does anyone have a wiring diagram they can share or would you post the steps for adding the starter button?
Subject to your findings after what Laner said, wiring a starter button is dead simple.
On the back of your ignition switch there is a permanent + 12 v tab among others. Identify it with a 12 v tester over to any ground. You don't want to use that one. Find another that becomes live when you turn the key on to IGN with the tester over to any ground nearby. Keep an eye on THAT tab.
Identify a wire coming up from the starter solenoid to some other tab on the back of the ignition switch. Disconnect that one at the switch. Install the starter button. It will have two tabs on the back. Run a wire from THAT other tab noted above over to either side of the starter button tabs and run the wire that came up from the starter solenoid to the second tab on the back of the starter button. Bob's yer Uncle....twice in this case. Now three times ! Nice fob, Bob.
