I'm not sure if the 1100 uses the same connectors on the wiring harness as the 1300, but Eastern Beaver sells what they call 'hitachi' connectors that mate with the 1300's factory quartet harness. Now, EB is up front about not wanting to ship an order that is less than $100, and he charges a LOT to ship small orders. So, go in with a buddy and buy a bunch, or advertise here for someone who is buying his fusebox and relay harness. I also found some alternative sources for these connectors in the USA, (sorry, I don't remember the source now - but Google will help you). Bottom line, most sellers don't want to be bothered to sell you one $6.00 connector because it costs them the same to type the label and package it as a larger order.
