I never want to do this again

Trying to feed that knotted clump of spurs from front to rear & through the tiny hole in the frame tunnel isn't the way!... I always feed the loom through from rear to front - so much easier...
2 x inner cables - one fed in under the horn & through to the void beneath fuel tank & another fed through the hole for the rear brake light switch to the same area.... then secure relevant wires to relevant cables with some electrical tape, apply liberal amount of grease/Vaseline & gently pull wires through the frame & out below the horn cast...
Then just repeat the process to thread the headset wire(s) up to where they need to be.
For me the worst part of the job on older Vespa models is the small steel tube you have to feed the rear light wires through.

^ This is the way I learned through trial and error. There were some seriously commical moments during the learning process! If there are any additional wiring for gatgets and other stuff be ware of the lack of additional space for it at the top of the steering colum cable/loom outlet before painting!

Just had to squeeze all my SIP speedo wires and low level fuel tap wires up through my 90 Racer, thats was a bit tight

Would having a small child as an assistant be any help with this?

Deffinitely not in my experience, but what did you have in mind?

I had though small hands to reach through might be a help.

Fitted a loom into a 100 sport smallie a couple of years ago- utter bitch of a job

[ArmandTanzarian]

I wonder how they do it at the factory?

[GLscoot]

I always build my own looms and using electrical tape to protect the wires, I build the loom in three parts, rear brake, stator > headset & horn loom, with the main loom I attach a single wire on the outside of the loom, this is now used incase any of the wires become damaged or the complete loom gets damaged. it is a nightmare of a job, but with either picture wire or the Ape throttle cable (extra long) it is a little easier. I have also got the digital speedometer fitted and had no issues with feeding that through either.

In the loom I once bought I thought the quality of wire was very poor as was the plastic coating on the wire. What caused the loom to 'fry', was it the headlight

[storkfoot]

No the metal battery clamp wore through the coating on the leads to the battery. First I knew was stopping for petrol in Germany I had a plume of what I thought was white smoke initially. It was the battery acid!

When I got home, I took the tank out and cut the wiring back as far as I could. A lot of the plastic sheathing had melted. I was still getting a short at the rear light so had to consign the old loom to history.
