I made some good progress on the remaining wiring in the past week. I was naive to think it was a one-night job, but it's nearly done now. All I have to do is tidy up the temperature sensor wiring, and wire up the Innovate LC-1 wideband oxygen sensor. I was so effing busy at work all week I didn't get to spend any time whatsoever on my mechanic's dyno, which he gave me free-rein over for the whole week while he was away at SEMA in the US. Not happy!
Anyway here are a few pics...
