Backup Alarm Buzzer Circuits

[mikester]

Who has a backup alarm on their Kubota UTV?

I don't have the buzzer installed on my machine and I want to use the BU alarm circuit to power an LED floodlight whenever the machine is put into reverse.

I think I found the OEM 2-conductor wiring harness plug for the bu alarm but one wire is always hot when the key switch is on and the other is always to ground.

How is the bu alarm triggered?

I finally found a better photo of the BU alarm kit which makes a little more sense to me that shows 3 sets of ends on the wiring harness. It looks like the square connector plus into the available 2-C plug at the back-top of the motor assembly for power. One end goes to a normlly-open? micro switch which mounts somewhere on the shifter mechanism. The other end goes to the buzzer.

I wish K didn't charge US$150 for the kit with $30 in parts. I'm not sure what they are thinking when the sell something like mirrors for $150 that I found for CDN$30 at a recreational sports parts dealer. $800 for a lexan golf cart windshield? Yikes, I thought $200 was expensive.
