PX125E frame and PX125E (LML) wiring to a P200 engine

Hey Everyone, 

Basically what I'm trying to do is take my PX125E with the PX125E (LML) wiring harness and hook up my P200 engine up to all of it.

After doing some reading and research I'm stuck.

Should I be using a different wiring harness and parts all together, or will it all work and hook up right?

Any input at all would be helpful.
