P Mag connection ( 4 hrs )

While preparing to connect "P-Lead R" to right Mag, discovered statement in E-Mag install guide to separate plug leads.  Contacted Trent at E-Mag, who said up to 5" can be bundled, but more will cause induction coupling.  So....spent couple hours revising all lead wires for P Mag using the recommended 1/4" silicone tubing on cable ties to create separators.  Next, connected P Mag per p. 26 schematic in Install Guide and Stein Air's schematic:  "P-Lead R" to Pin 4, with shield wire connected to Pin 1 as ground (added separate wire from engine stud nearby also to Pin 1)  This creates 3 ground paths including P-Mag itself bolted to engine case.   "P Mag 3A" connected to Pin 5, and Tach Output (white wire only) connected to Pin 6.   Finally, aligned blast tube to insure directly on "neck" area of P Mag per Install Guide.  Wrapped oil line with silicone tape (red) prior to applying cable ties.

revised so P Mag leads are separated...RH side

Wiring to Fuel Flow Transducer ( 2 hrs )

Connected "red cube" Fuel Flow Transducer (Electronics International FT-60) to wires from GEA24 J243.  Stein Air's Chris confirmed they recommend using the OLC-1 connectors supplied with transducer.   I staggered the 3 connectors to nest for a tighter package.  Used layers of heat shrink tubing followed by wrapping with silicone tape, then cable tied into bundle with CHT sensor wiring.

Mag P-Lead, Oil Temp, Fuel Pressure, Oil Press sensors connected ( 3 hrs )

Completed installation of P-Lead and gnd wire to LH Mag.  Connected Oil Temp sensor and bundled wires w/ P-Lead.  Soldered Fuel Press and Oil Press sensors at LH firewall, leaving extra lengths (just in case require re-do, etc).  Wrapped engine mount tube with silicone tape for protection, then cable tied "loops" of sensor wires to tube.

Mag P-Lead, etc ( 3 hrs )

Attached two -12 size cushion clamps to engine mount near LH firewall and Left Mag to route wires for Fuel and Oil Pressure sensors, Oil Temp sensor, and P-Lead for Mag (combined w/ a -4 and -3 clamp).  Clamped wires along upper rear engine mount tubing.  Referenced Stein Air's schematic for GEA24 J243 connector for wire to wire connections.   Josh Swenson at Stein provided tip for connection of P-Lead with ground wire:  After uncovering braided shield wire,  push braid backwards to open weave, then pull single wire for P-Lead out of open mesh ( I used a toothpick).  This enables the braided shield to become a "wire" to directly crimp on ring terminal for gnd connection (instead of soldering a wire to section of braided shield).  After practice with couple pieces, I decided this worked well for the P-Lead.  No soldering, only #10 ring terminals added to ends.   Included layers of heat shrink to each wire.  Even remembered to include the MS25171-1S silicone terminal cover for the P-Lead post.

Alt Field, Discrete #4 and Contactor Relay" connected ( 3 hrs )

Connected "Alt Fld" wire (from Master Switch position 3) to Alternator red wire (from gray  connector on alternator for Alt Enable Field Switch).  Connected "Discrete #4" wire from GEA24 J244 connector to white wire at Alt (connector on back of Alternator)  - to provide indication Alt output "OFF".  Per Stein Air's recommendation, I soldered wires instead of using crimped splice joints.  So most of time spent practice soldering.   Covered joints with two layers heat shrink for better toughness, and the extra lengths were doubled up and secured with cable ties to P909 Alt Pwr wire.  Added spiral wrap for extra protection (not in pic below).    Next, connected "Contactor Relay" wire from Master Switch (position 6) to Master or Main Battery Contactor Relay on firewall.  Crimped ring terminal on the Wht/Brn wire. secured to post along with ES Diode Master.  Used layered heat shrink at crimp, then covered this single wire with small dia spiral wrap all the way to firewall opening.

Doubled extra length of wires after soldering, covering heat shrink.

Ignition Wiring (  3 hrs )

Received re-done Floormats and Baggage Floor from Abby at Flightline Interiors.  Much improved fit -- Yay!  [ Note:  after initial trial fit Oct 23 I determined the width of the floormats and baggage area were from 3/8" to 7/8" short - leaving considerable gaps.  Several pics of other RV14's with same interiors showed essentially no gaps.  Abby readily agreed to remake them for me, explaining the templates haven't changed, but a new person may have incorrectly made mine ]   Completed adding cushion clamps to LH side top ignition wires.  Since the red silicone wires for PMAG are larger dia, needed to upsize each from 1-2 steps (ie WDG 4 --> 5 w/ single wire, and WDG 6 --> 8 for two wire locations.   Bundled Mag (bottom cyl 1& 3) with PMAG (top cyl 2 & 4) together behind engine -- another challenge to reach.  I think I can see the light at the end of the wiring tunnel!
