Trying to tie in both a camper harness and an aux battery harness for my 72 K20. Hoping to get some detailed underhood routing pics for:

1) a camper harness with an OEM aux battery to see where the red camper (+) wire goes along the firewall then heads forward
2) where the red camper wire ties into the aux battery harness
3) what the aux battery J-blocks/wires look like mounted to the RH fender
4) did GM buddy tape both the camper (+) red wire AND the aux harness red wire to the forward lamp harness

I want to make sure everything is wired correctly so as not to fry any lines and will use the pics in conjunction with what's in the assembly manual. I know the aux harness is buddy taped to the forward lamp harness.

Appreciate any help, thanks!
