Starter stays engaged ONLY in park???

Thanks. I don't know if you saw in previous posts, but the seatbelt interlock has all been removed. The new harness coming this week will have all the factory interlock wiring, so if I need to I can do a "proper" bypass. At least I'll know what was done as opposed to whatever the previous owner did...which is who knows what.

With the higher than normal resistance between the power in red and yellow starter wire, how do I find the cause? Do I need to pull apart the steering column and inspect the harness?
