Modern Vespa

Any Nexus 500 ppl here? I changed the fuel pump on my Nexus 500. The wires under the fuel cap had come off so unsure which wires go to which connector. There are 5 connectors and 2 each wires from the fuel pump & the fuel gauge. The bike has been sitting for a few years & doesn't even turn over (no current to the starter) so have some troubleshooting to do with the wiring. Also, hazard lights seem stuck on & don't go off when you turn the key on then off again.

JimC maintains an archive of scooter manuals that may help with your wiring:

Thanks I have that manual but the top of the fuel tank isn't in it apart from general coverage in the wiring diagram. Think I may have it worked out now. Got the pump to run, just got to reassemble it now.
