So I've had more time than I thought, and the Koso Dash was easier to install than the instructions made it sound.
Here's me being impatient and opening it while at work.
And the size difference between original and RX2.
Started figuring out the dash on Thursday night and drew out my own "wiring diagram" to help myself.
Seemed easy enough once I'd got my head round it. So I got hold of the sub-loom from the original clocks (I've got a spare on the way to replace it if I need to go back to original) and started wiring that in as it was easier than butchering the main loom. I kept forgetting to put the shrink wrap on before soldering, so ended up just taping a couple of joints
The un-used wires from both ends were taped up to neaten things. At this point I left everything else loose to allow for any routing issues, as I didn't fancy wrapping and un-wrapping something because I'd got it wrong.
Yesterday morning I managed to finish the soldering on the clock loom before work and started to figure out where everything would go.
Then this morning I got the clock mounted before work and looked at how to mount the speed sensor. Because I have caliper brackets for my 929/SP1 calipers, there wasn't anywhere I could mount the bracket supplied where it would work. So I made up a small right angle bracket at work and used it to mount the sensor using the fork pinch bolt.
This afternoon I cracked on and connected up the positive and earth for the clocks, then begrudgingly used one of the parallel connectors provided in the pack to connect up the ignition switch. Didn't take a photo as I don't want to shame the thread with those horrid red things.
Temp sensor. It was easy as the sensor provided is exactly the same thread as the original, and the coolant didn't piss out because the airlock kept it in. No need to drain the rads
I may actually change the temp sensor to appear on the oil temp part of the dash as I have to choose between the time and temp atm, bit annoying.
Then my speed sensor solution.
Lovely mess of wires to tidy up. I could actually do with building a new loom, there's so many new wires running everywhere from the dash, low beam relay, voltmeter, alarm, manual fan switch and charging system upgrade.....
Then was to flick the ignition on to see if it was working, and it was, perfect.
Apart from the tacho, that wasn't working at all. I had thought that I could just plug the tacho into the original rpm wire coming from the CDI and it'd work. Nope, wasn't having it.
Solution was to use one of the supplied wires to put in a parallel feed from the rear coil pack. I at first managed to connect it to the negative on the coil and it wouldn't work. 10 minutes of head scratching later and I swapped it onto the positive and it worked.
The correct setting for the tacho was four stroke 2 piston. Probably because of the wasted spark ignition, but that's what worked.
I had clearance issues with the top fairing at first, which was a bit annoying as I thought the dash was set perfectly for me to see it. I tilted it forward 1 position and it just fits. I can still see it pretty well, and it'll work better for chin on the tank riding (not that I do much of that anyway).
The tacho still isn't working perfectly however, the signal being analogue means that the digital tacho is very jumpy and doesn't read perfect. I've been reading online from google searches and the solution seems to be a resistor put inline with the signal wire, but no-one seems to specify what resistance? Maybe it's different for different bikes? Anybody know?
Anyway here's a short video of it working.

Will just have to wait til tomorrow/when it's not raining to test the speedo properly, as I got the tire circumference from a bridgestone size table. Should work, if not I'll just have to measure it by hand.
I still haven't got that exhaust badge fitted yet though, maybe tomorrow.
