Have a 03 Sierra SLE ext Z71 sb with a Leer cap on back.
Does anyone know a back up sensor system that I install?
Back up with a Echo behind you, the little thing is not in the mirrors!
And why would a little Buick have it as an optain but not a truck

I may be wrong, but I think www.jcwhitney.com has these.
