NOTE: The intent of this section is to install all of t he wires
that will eventually hook up to components supplied in theAvionics
Kit or Optional kits such as Lighting or Autopilot. Even if not
installing optional systems route the wires for themso that in the
future these systems can easily be added.
Note: If installing a Garmin GTX 328 (Euro / mode S transponder
customers) route
wires through the forward hole in the F-1202B Panel Base
only!
Step 1: Insert the modified rubber grommet (from the previous
page) into the F-1201AFirewall Upper penetration location.
Step 2: Cut a 36 inch length of DUCT NT 5/8 to make the F-1204Y
Wire Run Conduit. Cuta 7/16 diameter hole in the wire run conduit
for the wires coming from the top center ofthe F-1204 Center
Section Assembly (see Figur e 1). To help pull wires through later,
addone string going from the hole to the left end of the conduit,
one from the hole to the rightend and one going from one end to the
other. Leave enough excess string that when theconduit is installed
the string will hang down below the bottom of the airplane.
Whenpulling a wire with a string add a new string for future
use.
Step 3: Using the clamps and hardware called out in the detail
view in the right side ofFigure 1 install the F-1204Y Wire Run
Conduit. Center the wire run conduit about thecenterline of the
airc raft with the hole cut in Step 2 over the snap bushing in the
F-1204Center Section Assembly.
NOTE: Look at Figure 1 to determine the type of f uel flow
transducer supplied inyour kit, then complete the appropriate Step
4.
Step 4 (FT-60): Remove the forward most bolt holding the FT-60
Fuel FlowTransducer. Final-Drill 1/4 the cushioned clamp called out
in Figure 1 thenslide it over the bolt and reinstall the bolt.
Step 4 (Flo-Scan): Remove the inboard most bolt. Make the
VA-188B Standoff asshown in Figure 2. Install the standoff and a
cushioned clamp on the FLO-SCAN
Fuel Flow Transducer using the hardware called out in Figure
1.
NOTE: When routing cables and wires some snap bushings may need
to beremoved and the wire or cable passed through the hole. Slit
the snap bushing,place it over the cable and snap the bushing back
into the hole.
Step 5: Route the straight BNC fitting on theWH-RV12-SL-ANT and
WH-RV12-TX-ANT down
through one of the snap bushings in the F-1202BPanel Base, over
the rudder pedals, and throughthe fuel flow cushioned clamp.
Continue to routethe WH-RV12-SL-ANT through the snapbushings in the
F-1202F and F-1203ABulkheads. Lay the cable through the
wire notches in all three F-1276C SystemBlocks. Route the cable
through the snap bushingin the front of the F-1204 Center Section
Assembly.
Step 6: Route the ES RS 279-374 Phone Cable
through the right end of the F-1204Y Wire RunConduit (Use one of
the strings installed in
Step 2) then down through the wire run hole inthe top of the
F-1204 Center Section Assembly(16 inches should remain protruding
from the rightend of the wire run conduit). Slit then insert a
snap bushing in the top of the F-1204 CenterSection Assembly as
called out in Figure 1. Routethe cable forward through the same
route used bythe WH-RV12-SL-ANT. Route the cable throughthe snap
bushing in the F-1202K-R Inst Stack Support.

NOTE: When routing wires in this section between the region over
the rudder pedals and the snap b ushings in the F-1202BPanel Base
check that the wires will easily fit through the notch in the
forward edge of the F-1230 Tunnel Cover.
