2.2 Power Wires
The SAT radio tuner will be located in the trunk and needs a power supply there. Luckily there is a
good source of power from the correct fuse (#37) already in the trunk: a 2.5mm wire that carries the
power from fuse #37 to the amp on the right side of the trunk.
Remove the trunk floor carpet and rear cross panel trim at the lip of the trunk. Remove the right side
trunk trim, at least far enough to allow room to work with wiring at the amplifier. (See Appendix F)
The power wire to be tapped is HOT at all times. Disconnect the battery.
Do not use the power supply wires within the CDC harness for the SAT tuner module.
Remove the wiring harness from the amplifier and splice into the +12V power wire. It is the large
Red/Blue wire at Pin 13 of the Bose Amp connector. For non-Bose amps, the wire is located in Pin 1.
Reconnect the wiring harness to the amp and run a new wire, at least 18AWG in size, from the splice
just made, across the rear of the trunk (under the cross panel trim), behind the left side trunk trim,
into the hole where the SAT module will be installed. Reinstall all the trunk trim.
Alternative: connect a new power wire to the “30” connection on the power bank behind the fuse box and run to
the trunk. An inline fuse between the SAT module and the power connection is required if this method is used.
Install a new wire terminal onto the end of the power wire and install into Pin 2 of T8r. T8r is a
new wire terminal housing in the picture above. It is a small connector with wires arranged in two
rows of four wires each. Install another new wire terminal into Pin 1 of T8r and connect to ground
in a convenient location. Check for good ground by using a multimeter to check voltage using the
new power wire in Pin 2 for positive voltage. The power on this wire is hot at all times if the
battery is connected. Close the wing sides into the T8r connector, it is complete.
