Select one of the 7” pieces with a remaining red wire (and no black wire). 
Solder it into TB12’s RT terminal. Insert it from the component side and 
 
Cover the accompanying drain wire with ½” of the outside gray jacket 
material. Solder the drain wire into TB12’s GND terminal. Insert it from 
the component side and solder it on the solder side.
 
Select the other of the 7” pieces with a remaining red wire (and no black 
wire). Solder it into TB10’s RT terminal. Insert it from the component side 
and solder it on the solder side.
 
Cover the accompanying drain wire with ½” of the outside gray jacket 
material. Solder the drain wire into TB10’s GND terminal. Insert it from 
the component side and solder it on the solder side.
 
Select one of the 7” pieces with a remaining black wire (and no red wire). 
Solder it into TB11’s LT terminal. Insert it from the component side and 
 
Cover the accompanying drain wire with ½” of the outside gray jacket 
material. Solder the drain wire into TB11’s GND terminal. Insert it from 
the component side and solder it on the solder side.
 
Select the other of the 7” pieces with a remaining black wire (and no red 
wire). Solder it into TB9’s LT terminal. Insert it from the component side 
and solder it on the solder side.
 
Cover the accompanying drain wire with ½” of the outside gray jacket 
material. Solder the drain wire into TB9’s GND terminal. Insert it from the 
component side and solder it on the solder side.
 
Select the other of the 9” wire that has black, red, and drain wires on both 
ends. Insert the wires from the component side and solder them on the 
solder side: 
1.  Red wire to TB8 RT terminal. 
 
Black wire to TB7 LT terminal..
 
Cover the accompanying drain wire with ½” of the outside gray jacket 
material. Solder the drain wire into Drain wire to TB7 GND terminal. 
Insert it from the component side and solder it on the solder side.
