Wire routing
I ran two bundles, one to each bank of the engine. On the right side I ran the bundle just below the angle that is foot or so below the baggage door opening. I ran the left bundle at the same place on the left side.
On the right side are: Cylinder #1 and #3 EGT and CHT, Alternator output,(#8 gauage wire), and Field wire.
On the left side: Cylinder #2 and #4 EGT, and CHT, Oil temp, Oil pressure, and Fuel pressure sensor wires.
This setup has 1130 hours and ten years on it without any problems.
