Splicing Twisted or Shielded Cable
WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2012 GMC Yukon XL, 2012 GMC Yukon, 2012 Chevrolet Tahoe, 2012 Chevrolet Suburban, and 2012 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.
Twisted/shielded cable is used in order to protect wiring from electrical noise. Two-conductor cable of this construction is used between the radio and the Delco-Bose® speaker/amplifier units and other applications where low level, sensitive signals must be carried. Follow the instructions below in order to repair the twisted/shielded cable.
- Remove the outer jacket (1). Use care not to cut into the drain wire of the mylar tape.
- Unwrap the tape. Do not remove the tape. Use the tape in order to rewrap the twisted conductors after the splice is made.
- Prepare the splice. Untwist the conductors and follow the instructions for Splicing Copper Wire Using Splice Sleeves . Staggering the splices by 65 mm (2.5 in) is recommended.
- Re-assemble the cable.
- Rewrap the conductors with the mylar tape. If the mylar tape is damaged, use 3M product AL-36FR to replace the damaged mylar tape.
- Use caution not to wrap the drain wire in the tape (1).
- Follow the splicing instructions for copper wire and splice the drain wire.
- Wrap the drain wire around the conductors and tape with electrical tape to replace the outer insulation.
- Tape over the entire cable. Use a winding motion when you apply the tape.
NOTE:
Apply the mylar tape with the aluminum side inward. This ensures good electrical contact with the drain wire.
