I am installing a backup camera and am trying to locate a place under the dash to tie the reverse sensor wire to the wire feeding the backup lights. I could route the wire under the vehicle to the backup lights but would prefer to do it under the dash if possible. I would like a specific location to do that. Thank you

You'll still have to go underneath to the transmission. That's where the switched circuit starts.

So are you saying that the light green wire that goes to the back up lights goes directly back to the lights and you can’t access that wire under the dash or the hood?

It looks like there should be a light green wire that is intended to feed the interior rear view mirror if you have the compass version. The lower part of that harness should be there even without the mirror. Unfortunately the connector and splice numbers are not listed in the locations menu! As such you may have to find it under the van and trace it inside.
