I then route the wires coming from the cylinders (one EGT and one CHT each). They ride piggyback on the big cables I installed yesterday.



Then I fabricate the oil pressure sensor cables, other cables are included in the instrument's hardware.
I'va also installer the manifold pressure tubing.



I then fabricate the second ground cable going from the firewall to the engine. On one side the cable is bolted using a sump bolt, properly retorqued after installation. On the other side I had to rivet a nuplate on the firewall with some difficult access.
