What should I look for when repairing my car's wiring harness?

Tie the wires to branch according to the original type of harness. The exposed portion should be of the specified length and there should be no exposed portion at the joints. Insulated sleeves should be added to the welds and tied. If the connector of each wire is not the original color, add a set of original color plastic tube for easy identification. The connectors of the wiring harness and electrical equipment should match. If the original ones still work, then use the original ones. If the original doesn't work or is rusty, it should be replaced with a new one. If there is no new one available, the original should be cleaned before reusing it.1. First, remove the insulation wrapping from the burnt harness, cut off the ends of the burnt wires, reconnect the burnt wires with wires of the same size and length, and wrap each connector with insulating tape.2. When wiring, divide the ends of the wires to be connected into two halves, and twist them together separately. Then, twist the two twisted wires together again, bend them to be parallel and close to the wires, and wrap them with insulating plastic sheeting, as shown in Figure 1. If the harness is completely broken, it can be connected with short wires. Connect the joints of each wire in a staggered manner, with each joint wrapped in insulating plastic sheeting. Finally, the connected wires should be wrapped in insulating tape. When connecting wires, the length of the original harness should not be shortened. If the number of burned wires is large, cut one wire and then connect another to prevent misconnections.3. Harness trimming: The harness should be trimmed again after removing the maintenance or wires. Can use white gauze or plastic tape for half-folded wrap. After the harness is wrapped, dipped in insulating paint or asphalt paint, drying or drying, in order to increase the strength of the harness and insulation. The reconnected wiring harness should be firm, reliable and beautiful, which is conducive to the performance of the whole vehicle and driving safety.-4、About BBC Electronic Products Network platform related to the introduction and sales of products briefly: BBC Electronic Products Network - a professional agent / production / sales of a variety of {connectors | wiring harness | wire and cable products }; if you have a related [connectors | wiring harness | wire and cable products] procurement / purchasing needs or would like to buy / to understand which connectors | wiring harness | wire and cable product solutions that we can provide, please contact our Division below!
