What is a non-SRS wiring repair? It is the repairing of an electrical component that is not part of the supplemental restraints system circuit (usually identified by yellow wire looms). As technology increases on vehicles, so does the number of components that utilize electricity. Many of the sensors and modules are becoming smarter and more sensitive. If the wire is too long, the wrong gauge, or spliced in the wrong location, it can cause malfunctions in the components that it’s powering. Many OEMs have different restrictions and guidelines for repairing wiring that does not control SRS components. On the other hand, there are OEMs that don’t allow wiring repairs at all, so full harness replacement is the only option. Let’s take a closer look at FCA/Stellantis.
FCA/Stellantis allows repairs to wiring harnesses and some connector pigtails. The FCA/Stellantis subscription website has the procedure on how to properly splice a wire. This procedure should be followed any time a harness repair is made.
The document can be found in vehicle-specific service manuals under: Service Information ➤ DTC-Based Diagnostics (or Non-DTC Based Diagnostics) ➤ Circuit Testing Procedures ➤ Standard Procedures ➤ Wire Splice.
The procedure specifies crimping the wires with a splice band, soldering the connection, and sealing the splice with sealant-lined shrink tubing (part number 04778570 or equivalent). A video is offered in many service manuals to demonstrate the procedure.

It is important to read and follow OEM procedures to be certain what electrical wiring repairs can be carried out to help achieve a complete, safe, and quality repair.
