AHAH!! I just figured out that the 2017 Zforce 800 Trail is wired differently(and possibly the 2018's) The connection was working perfectly BUT they changed it so that engaging the belt BREAKS the connection to inhibit the rev limiter, NOT the other way around, so I simply separated the wires and taped the ends which made the seat belt indicator stop flashing and was able to finally exceed 16mph!

Is there a way to make this post easier for others to find so that they don't make the same mistake I did by wiring or soldering them together?
