Can you show me the pigtail end of your ignition switch? Our Church tractor M4900 SU was recently vandalized. Someone stole the ignition switch and so far the local Kubota dealer has been unable to get the correct switch for us after 3 attempts. The only plug I see, after taking the dash apart to get under it, is a 6 prong plug with only 4 connectors (wires) on it. See the picture of the church tractor plug attached. A part number would also be helpful.
Thanks

I got a new switch from Kubota. They said the switch they sent was the right switch and that they just failed to include the pigtail that went with the switch. I’ll try to install it this weekend to see if it’s the correct one.
