Hi, still in a panic. If you havent resolved or turned to drink by now I think I can help. From what Ive seen of the zero loom its aimed at the newer stalks which switch a relay to ground. The older stalks switch 12v direct to the lamps, to make the zero loom work you need to change the 12v to the relay coils to ground. The relay coil is on pins 85 and 86.
If you switches are the newer ones small brown wires from light switch then your okay. But.
There may be a problem with the loom, the one I helped wire had some wires crossed in the relays I cant remember exact details but I think one relay had both power feeds across contacts and the other had dip and main across contacts pins 30 and 87. You need to make sure you have a power feed and a connection to a light on pins 30 and 87.
Sorry its a bit late replying. Good luck.
