I am looking to replace the wiring loom in my U.S. model (non battery) 1967 Vespa SS180 and want to know which loom to buy. I have a Pinsaco electronic ignition kit in the SS right now and am still having trouble with the spark. It seems there are several options but I want to make sure I buy one that has wiring for the neutral light on the headset (the evil eye). Does anyone know which loom I should be looking at? Thanks.
