Is it about blind spot during driving or park sensors?
During driving, the modern sensors are useless without the matching
counterpart ECU, communicating via CAN bus and stuff.

If it´s about park sensors, I used mid 2000s Audi A6 sensors and the
relevant ECU to activate the reverse beeper.

Not even sure if ECU is using CAN bus, but if so, apologies it´s still
useless on the standard Vanagon.
In the end, Dug´s solution is the way forward, I just like the sensos
being nicely integrated into the bumper, not "attached" :-)
