Seems there are several of us near the same stage of the build. I'm just completing the 912is wiring - the individual wires that is. I wrapped up this evening's work after managing to get the HIC connectors fed through the firewall. I'll suggest feeding these large connectors and harnesses before running individual wires such as the Start / Backup Battery switch wires. Eventually the wires will be neatly bundled but, at this point, it's just a jumble of wires.

Nice to have a heads up on the radiator hose before I get to that point.
