83 air cooled full camper aux battery set up
Posted: Tue Jul 11, 2017 2:40 pm
83 air cooled full camper with factory installed 5-pin relay under driver seat. Wanting to add battery in order to primarily be able to install one or two 12v sockets in rear to run a fan at night and maybe charge phones when van is off (on the road currently and the south east is hot and muggy making for challenging sleeping). Relay currently is wired as follows (I know this isn't correct and have looked at a variety of posts and hence I am looking here for help):
terminal 30: red wire to fridge fan or camper indicator lights or fridge?
Terminal 87: red wire from starter batt
These two seem to be incorrect - I think 30 should be from starter and 87 would be to aux positive post
Terminal 87 center: also to rear/camper stuff
Confused on center terminal because as I understand that was for a cig socket under the pass seat on later models, but not sure about ours - thought it was supposed to be a 4 post unit. Would give power when alternator is running but not otherwise I think - nothing in the camp stuff was designed that way so ... it is a stock VW part though #411 915 511 B
Terminal 86: blue from alternator (correct)
Terminal 85: red/black ground (correct)
Other note: fridge fan works when van is parked/off.
Finally, suggestions on wiring in a 12v outlet would be great!
Many thanks in advance! Hoping to knock this out soon!
