I need to fix the sensor attachment this weekend, but the basic placement (under the running lights spar) and wiring runs are final.

for newbies to the forum that get links blocked:
The install took about 3 1/2 hours, since I'm a bit slow. I took others' advice and went with the sensor placement underneath the running light / turn signal spar. I ran each wire along its spar and then up the chassis tubing underneath the front cowling. I mounted the CPU using 3M Dual Lock tape underneath the center bracing, above and behind the dash.
For the power switch, I drilled a hole in the dash (fiberglass) with a plug cutter, then routed the hole out a bit until the switch body snapped in nicely.
I wrapped all wires, except for the sensor wires running along the spars, with expansion sleeves to match the existing wiring. I tidied things up with black cable ties, and since it can get a little windy in the cockpit, I made sure all wires were doubled up and tied down securely.
The only remaining issues (so far) are:
- the spars don't stay level, since they are only held in with one bolt
- the sensors' wires are not hidden in the spar
- I could not get the sensors level without an ugly cable tie
To fix the spars not staying level, I bought a tap & die set, plan to fix that issue this weekend. I am going to add another bolt at the base to keep vibration from rotating the spar.
I'm not quite sure what to do about the sensors' wires not being hidden in the spar. I fix it, I'd have to cut the wire to feed it through, and I'm not sure I hate the cable ties enough yet to do that. I may have to do it anyway, but I'm still thinking.
The cable tie holding the sensor to the light assembly on the end, though, has me very unhappy. I did screw the sensor to the assembly, but with the shape of the assembly it's just impossible to adjust the sensor properly. I'm probably going to have to fabricate a new housing. Oh well, I planned to redo the lighting completely anyhow.
Anyhow... there it is.
