Well, a short time in the shed and the hole for the indicator switch is drilled, the switch is installed (but not completely wired as I'd forgotten the colour convention for LHS and RHS!) I just remembered that's why I wrote it down in this blog!
I also fitted the socket for the AFR meter (the small black connector under the grey loom box section in the stunningly interesting picture). This has fused 12V supply, Earth and RPM connections. Let's hope the RPM is a reasonably strong signal or I'll have to fit some sort of amp (here we go... more electronics...)
With these final fitments I believe the dash is finished!!!
