Does this work with a manual shift vehicle?
A shopper on Dec 1, 2014
Best Answer: It would work as long as you have a backup light or a reverse switch. Triggers are needed from the backup light, brake switch and switched power. I think you could use the reverse switch with a relay but all the connections are tapped into the positive side of those triggers.

I read one review about some difficulty using this on a vehicle with a higher bumper. I would install in a steel metal bumper on a 1977 VW westfalia bay/transporter camper bus. The wheel rims are just 14". I don't think the bumper is particularly high, but if you have any thoughts please let me know. Any other potential conflicts that I should know about before purchasing?
A shopper on Dec 1, 2014
Best Answer: My experience: you'll want to put the sensors as high as you can (around 22 to 25 inches) but it also depends if your mounting surface is perpendicular to the ground (even 1 degree will make a difference). You'll get false readings off the pavement if they're too low or they're pointed downward. I saw some angle adjusters for the sensors on ebay that you might want to consider if it doesn't work even at your highest point. On your Westfalia you might want to consider putting them in the body above the bumper (??). They're surprisingly accurate (I have some scratches on my lower front bumper to prove it when I tested the "stop"
