In order to run it on the bench you really need to pull out the wiring harness. There is a safety switch and a triple relay under the dash and the harness plugs into them. Also 2 wires go to #9 and #10 in the fuse box and 1 wire goes to the switch on the heater lever that turns on the fan. If you pull off those wires and pull out the relay and the safety switch the harness is all self contained and is fairly easy to get out of the bus. I have taken 4 of them out in about 1 hour at a junkyard. It's just held on with zip ties under the bus. Don't try wiring it up yourself, that's not really a good idea. Also having the wiring harness out makes it easy to inspect the wires and see if any are shorting (yes I have had them not run because of that). PM me if you need any help, I have rebuilt a few of these and their smaller brother the BA4.

Another thing I noticed: is your intake hose cracked in the picture below?
If it is replace it. The intake should be very far away from the heater, otherwise drafts could potentially cause the heater to overheat and catch fire.

Well, i pulled the harness out along with all the relays & switches. Came out a lot easier then i would have thought. The wiring all seems to be in great shape. Now i'm wondering a few things about what kind of ground wires to run & where? Most of it is all hooked up ready to run now.
This part of the switch only had 1 wire going to it, and it was brown (ground). Been trying to look at some diagrams to find out if the wire was going to the 'K' or the '31' on this switch

Here are some wiring diagrams. Not sure if you have seen them. It looks like the 'K' wire is used. I don't see a '31' on there. Terminal 31 is the ground circuit on German cars. Can you tell by looking at the terminal if there is any wear or signs of it not being used? |
