Not 100% sure but I know the 550 loom routing is different than that Ted. It goes under the lower yoke and is held by a clamp which bolts onto the yoke. Whilst there is no 500 routing diagram to my knowledge I think the 550 routes better. There is also another loom hanger which goes behind the tank mount rubber.
