I installed a switch pannel from Painless (www.painlessperformance.com
) that has an ignition toggle, acc toggle, and momentary push button start. After staring at wiring diagrams until my brain hurt i decided to do it the old fashioned way. I disconnected the ignition switch harness that's on top of the steering colum (way up under the dash) and used a jumper wire from the hot lead (the larger gauge red wire) to figure out which wires were ign, acc, and starter. After i figured out how to hook everything up, i ended up mounting the pannel in the cup holder on my tuffy console- it was a near perfect fit.
Now my key stays in the ignition to prevent the steering wheel from locking, but serves no purpose other than that.
