He's got an AT, but I think the early cars didn't use the electric AAR. If 
the 69 did have an electric AAR, it would connect to the currently open terminal 
on the front relay.

The wire to the brain is actually in the engine compartment (#19). It's 
located in front of the engine on the firewall, just in front of the #3 cylinder. 
If you ground this wire with the key on, does the fuel pump run? It should, 
otherwise then I'd suspect the wiring or a relay. It's also a quick way to check 
that the relays are functioning.

You might want to try an import salvage yard in your area. Take the known bad 
one with you to match it up (the terminal numbers or an actual part). VW had 
a tendency to use the same part for many models.It might have a different 
shape (like the one CIP has), but it's function would be the same.
