This afternoon I worked on different wiring
sections. I installed the ignition
wiring harness to the A1 and B1 electrical connectors. I removed the metal clamp from the Ignition
Module A and inserted the exposed shielding of the harness and reinstalled the
clamp. I routed the harness to the rear
of the engine and cable tied it in place.
I inserted the wires from the main wiring bundle through the firewall
into the female connector and then put the connectors together. I also
located the ‘forked’ purple wire from the main bundle and routed it back to the
Ignition Module. I removed the A2 and B2
connectors from the metal bracket, removed the seal plugs and inserted the
wires into the connectors. I then reassemble
the connectors and reattached them to the metal bracket. I cable tied the purple wire to the pitot
tube.
I located the Oil Pressure wires (red, white/yellow)
in the main bundle and crimped on the appropriate spade terminals. I routed the gray Oil Pressure cable to the
rear of the engine and up to the engine shelf.
I cut it to length and attached the appropriate spade terminals and
connected them to the red & white/yellow wire spade terminals. I ran the purple/blue right CHT (cylinder head
temperature) wire down to the bottom of the engine, crimped on the terminal and
attached it to the CHT terminal post. I also ran the purple/yellow left CHT wire
and the white/brown Oil Temperature wire down to the bottom of the engine and crimped
on the terminals and attached them to the appropriate terminal posts.
I ran the Generator to Rectifier cable to the
engine shelf and attached the ends to the Rectifier terminal block. I also ran the Tachometer cable to the engine
shelf and made the necessary attachment to the wires from the main bundle. I put cable ties on all of the wires to
secure them in place. I attached the ground
wire and the starter power cable to the starter.
I cut the rubber hose to make the manifold
pressure tubing and installed it from the nipple on the compensating tube
assembly to the nipple on the manifold pressure sensor. I also cut the rubber hose to make the fuel
pump drain line. I straightened the ¼”
aluminum tubing and fabricated the drain tube.
I installed the drain line, both rubber and aluminum tubing and
installed the pipe clamps, cushioned clamps and cable ties to hold it in place.
