Question: Ignition and T4 universal wiring kit

"Keep the stock ignition." What does this mean? Keep the stock switch?

There is only so many ways around this

1--Replace the switch? With what? Unless you have a custom dash, you need a switch that fits

2--Me, I'd add one more wire to "keep" the factory scheme with IGN1/ IGN2, or as you say, bridge the two

3--You could use a diode wired from the start wire to act as IGN2. You need a diode to keep from causing a feedback situation. You can buy the largest amperage you can find at radio shack, wire from the start wire to IGN1, with the band of the diode towards the start relay end

4--You could convert the start relay to the later Jeep style, which has an extra set of contacts which perform the IGN2 function

5--You could wire a second relay, coil in parallel with the start relay, one contact to battery power, and the other contact wired to IGN1
