Have to fix the wiring the PO did when he installed heated grips. Wires were pulling out of the connectors where had plugged into the license plate light (I believe, I still have to sort some of the wiring). A local dealer was nice enough to let me root around in a pile of old harnesses they had, but there were no connectors like the ones I needed. So, next source appeared to be in Japan (with shipping a tariff - eek!). Luckily, found a source in NJ that (hope I don't break rules here) I feel deserves a shout out. https://www.cycleterminal.com/ Good variety, accepts small orders, price was right, shipping was cheap and quick.
Been using Cycleterminal for many years, very good source. Also for other wire up needs I like DelCity.
Here's list of suppliers I've used over the years. I need to check my paperwork, last year I was able to find ST1100 RR hybrid Sumitomo connector (both 6,3mm and 9,5mm terminals in 1 housing). https://www.corsa-technic.com https://www.bmotorsports.com/shop/index.php/cPath/109 https://www.easternbeaver.com https://www.ksvlooms.com/collections/all-items https://motorcycleconnectors.com https://cycleterminal.com https://www.automotiveconnectors.com/connectors-and-accessories.html https://www.efihardware.com/products/c293/Connectors http://www.vintageconnections.com/ https://kojaycat.co.uk/ https://www.3waycomponents.co.uk
