I believe the connections between those 2 years are different

You'll need to swap the stator between the two bikes.

This, 89 has different connectors.

Jared maybe send him a link for those connectors you used on my stator wiring.... Very clean and also weather tight.

just change out stator and flywheel. The Atc setup was a little different. The plugs coming from the stator are different in 89 than any other year. All bolt right up no problem.

Why not transfer the 85 CDI and wiring to the 89?  When I put my 86 ATC engine in my 88 TRX for a while, I also replaced the 88 CDI with the 86.  The 86 engine didn't want to run with the 88 CDI because it had more advanced timing by 2 degrees.
