I just did one in my 2002. If the wire colors didn't change most of what you need is in
Push Button Ignition Question
I left my clutch switch intact, but if you wanted to bypass it when using the push button and keep it intact while using the key without pulling the fuse, instead of running a switch to the yellow wire like u did, you would run it to the yellow with red tracer that comes out of the clutch switch instead.
The only other issue I had that I didn't update my thread with is the black with white tracer splits into two smaller wires with same color, I only tapped the one for the radio and missed the cigarette lighter, so either get both, or tap into it before it splits.
If you need any help, let me know, while it's all still fresh in my mind, lol
Mines a little over complicated, since I wanted an rf fob and a buzzer, and relays due to some switches being low all rating, but the basic idea is the same, and might get you some more ideas. I highly recommend drawing it all out on paper fist, even if it's quick and sloppy like mine, lol
