I hate to say this, but I bought a SIP loom for my US Rally 200 with indicators, and ended up having to modify it extensively to match the electronics in the bike. I had thought it would just be minor mods to get the indicators hooked up. But in fact the CDI, horn, and even brake pedal switch wiring were all different between the original harness and the SIP one. In hindsight I felt I would have been better off just making up a whole loom from scratch to match the original.

This may not be an issue for you if you are replacing other electrical components or you have already mapped out the connections and you know you're good. Just a heads up...
I really appreciate this thread. I found it when doing some research, and was about to buy the same loom.

The SIP loom seems fine, as long as you configure it exactly as it's designed, I guess. Using the same switches and such.

It seemed like a big pain to make it adapt to a 1974 American bike, with all the weird/unique things.

I'm just going to make one from scratch instead.

There's a screw in the headset for that ground. If memory serves, it's one of the screws that also holds the nylon cable routing piece.

Well I did it, re routed the loom in front of the steering lock. What is this black ground for and where does it go ?
Also I am putting in all new components and the euro style blinkers on the handlebars.
Mine was under a screw where the throttle tube stop is. But I'm on a VNA so yours won't be the same but it should go somewhere on the stem of the headset. The stem being the part that slides onto the fork tube. That chunk of metal. Should be able to attach it to that

Cables in and floor mat started but I torqued my back and have to sit out for a bit. So I will order parts. Next up I will do the front forks/ hub and brakes and the rear hub and brakes.
