Figure 2-7. Spider Installation Drawing
1. At one end of the shielded cable (7), strip back 2.0” to 3.5” of jacket while retaining the shield.
Trim away enough to leave 0.5” of shield exposed.
2. Strip 1/8” of insulation from one of the AWG #24 wires (4) on the Spider.
3. Connect the prepared AWG #24 Spider wire (4) to the shield (7) using an approved shield
termination technique.
Installation Options:
a) Slide a solder sleeve (6) onto the prepared wire assembly (4, 7) and shrink with a heat
gun. The size of solder sleeve must accommodate the number of conductors present
in the cable. Reference the following MIL-Specs for solder sleeves (M83519/1-1,
M83519/1-2, M83519/1-3, M83519/1-4, M83519/1-5).
b) Solder the prepared wire assembly (4, 7). Slide a piece of shrink tube (6) onto the
prepared wire assembly and shrink using a heat gun. The size of shrink tube must
accommodate the number of conductors present in the cable.
4. Strip 1/8” of insulation from the shielded cable end and crimp a pin (8) to each of the conductors
(7).
5. Insert crimped pins and wires (7, 8) into the appropriate housing location as specified by the
installation wiring diagrams.
6. Repeat steps 1 through 3 as needed for the remaining shielded cables (7). Use only one Spider
wire (4) per shield. Remaining AWG #24 wires should be tied back and dressed with shrink
tubing.
7. Wrap the cable bundle with Silicone Fusion Tape (Garmin P/N: 249-00114-00 or a similar
version) at the point where the backshell strain relief (10) and cast housing (1) contacts the cable
