How to identify “Gnd Starter Rel” wire?

[Baron71]

The KAI 46-07 Step 1 asks to cut and isolate the ground starter relay wire from the wires of the Regulator A bundle as shown in figure 1 no. 22.
However, all those wires are numbered from 1-9 only (see picture). In the Rotax Heavy Maintenance manual I can also just find this graphic without a detailed description what cable number grounds what.
I did see that the starter relay wire no. 8 (different strand of cables) need to be cut at a later time as well. Can anybody point me into the right direction where I can find information to identify the “gnd starter rel” wire from the Regulator A bundle?

I had to ask Van's tech support about this. The answer I received is that wire #1 is the ground wire. I confirmed this was the right wire by checking with a volt meter for continuity with the other end labeled 7 (the ring connector, not the quick connector labeled 8) in figure 1 of the Rotax wiring harness diagram. You'll cut this end of the wire in a later step (page 46iS-09 step 3). I cut both at the same time to remove any doubt.

Thank you very much. Very helpful. Checking the resistance also gave me the assurance that all other wires were not connected to the ground at wire #7.
