Hey Pleiades

Nice job!

Do you know if the blue/black wire on an XTR is long enough and routed in such a way to allow the connector to be fitted under the seat?

I think the waterproof Superseal connector is a good idea. However, it does require wiring up the pins and I don't have the right crimping tool for that. I've done it before with needle-nose pliers but the results are not great! The beauty of the connectors I linked to is that you just strip 10mm of wire, stick it on the hole and close the clip - job done. However, I'm not sure I'd use this connector if it has to stay under the side panel.
