Backup horns/beepers

[PapaBill]

Greetings all!

Some advice / recommendations are needed.

An Installation of a back-up beeper set seems like a decent idea since some are so dumb, or want you to hit them or too busy gabbin' and blabin' on their cell phones while walking thru a packed parking lot with allegedly no clue of where they are.

So they are getting put on. It is the most obnoxious sound ever heard - worse than Home Depot's fork lifts.

Do you guys and gals know where is the best place to tie the beepers in electrically?
a. Splice into the back up lights?
b. Manual Switch and run off the battery?
c. Reverse switch on the gear shift for the tranny?
d. Other?

Thanks everybody!
Semper Fi!

Pic: Via EBay, It appears they are tapping off the Back-Up Lights via T-Harness, however with the BCM being finicky I am not sure if this would create issues or not (Amp Draw)
I do not have one installed, so I cannot say for sure.
Another option would be (Tap) the Back-Up / Reverse Light (power) to trigger a relay and then tap a 12-Volt Power source for the horn.

If you have the 7 pin trailer connector, use that. Easy to connect with a T-Tap on the back side. I did it for my extra backup light.
