1974 Other Mercedes Benz Models Got a loose green wire that

I took wires off last year and now trying to use the wiring diagram to assure that all wires are were they need to be. So I find a green wire that I know comes from the 6 pin relay POST #4 on the relay bracket left (drv) side, just next to the distributor. This wire either was on the one of the ballast resistors, the .04 or .06 ohm resistors or from one the two fuses which are on this relay bracket. The wire has a round electrical connector which was screwed to either a ballast resistor or fuse. Can You Help? I have a Factory Service Manual CD-ROM with the wiring diagram, but when it shows this 6 pin relay it just states the green wire goes to a DOUBLE CABLE CONNECTOR TERMINAL 1 ZV. Where is this terminal 1ZV? Thanks, VW
