What I came up with is:
Park Lts = BK/YL
Run/Acc = bk/wt
Start =yellow (at least til it gets to the clutch switch or bypass, then yl/rd.
It's hard to figure it all out from the FSM unless you use it often, and I don't have a '98 anymore.
As ewcmr2 says, use a test light to be sure before tapping into or cutting any wires.
