Yeah...I bought it from the 3rd owner. It had some issues. Thanks @906UP

I'd like to see a wiring diagram and see what goes where. If it is a newer ecm, you might be able to jumper the wires for the seatbelt input.

Looks like there are 3 diagrams, only 2 of which have the seatbelt switch. A15 is the pin for the switch, and it is unused on older models.

Good idea, there's more changes than just a seatbelt safety thing though.... 2017 had different gears in the final drive on the transmission so the speed sensor signal is a different number of counts per rev and '17 & up had the "auto shift" option.

Yes. 2017 actually has its own diagram, and then 18 and up has another (the manual I am looking at only goes to 19).

So if I ground out A-15 that should signal that the seat belt is engaged?

 

[oakescharles]

Which one is a-15?

The 15th one ( ). There might be tiny numbers cast into the connector. I can't access the manual right now. Your machine probably doesn't have a wire in the connector for it, so you'll have to get creative and get something on the ecu pin. Be gentle.

hahahaha...If this resolves the issue, I am going to set it to a toggle switch to keep my kids from going to fast.

It's a great idea imho.

Looking back through, it looks like you've already determined you have a 2017 ecm? Why not just get the right ecm?
Like I said, 2017 has a different wiring diagram from all the rest, so who knows what else works or doesn't?

I don't like to spend money unless it's necessary. If it doesn't work, I will buy a new one. If I fry it, I will buy a new one. If it works, I can spend $200 on something else.

Finding A15
Looking into the connector at the pins.


To verify.
Here are some wire colors to check and make sure you have the right way. You

A17 is light green/red
A16 is white/yellow
A15
A14 is empty
A13 is light blue/white
A12 empty
A11 green/orange

Wish I could figure out a way to post pages from the FSM.

Well.......
What was the solution?

Located A-15. Inserted a wire and grounded it. Same process as 2017+ buckling the seat belt.

I’m glad it worked for you. That was an interesting one.
