Why This Harness Matters
Designed to the original routing, length and connector layout, this harness drops into place where the old one was removed, so the circuits it serves return to normal operation without rewiring.
Every wire in this harness has a job: delivering power, carrying a sensor signal or switching a component on and off. When the insulation hardens or terminals loosen, those jobs stop getting done reliably, and replacing the harness is the most direct fix.
Caterpillar machines rely heavily on electronic engine and machine control, which makes healthy wiring essential for performance and fault-free operation.
Frequently Asked Questions
Is this harness plug-and-play?
Yes. It is built to the original layout with matching connectors, so it installs in place of the original without cutting or splicing.
How do I know it will fit my machine?
Match the part number on your old harness, or send us your machine model and serial number and we will confirm before you order.
How long does shipping take?
Orders are shipped by express courier such as DHL, FedEx, UPS or TNT, and you will receive a tracking number by email as soon as your parcel leaves our warehouse.
Check Fitment Before Ordering
Before ordering, compare the part number printed on the label of your original harness with 1306572 130-6572. It is also worth comparing the connector shapes and the number of branches with our product photos. If your machine's serial range or engine variant differs, send us your machine details and we will confirm compatibility before you buy.
Warning Signs to Watch For
Watch for these symptoms:
- Recurring fault codes linked to this circuit
- Cracked, hardened or chafed insulation
- Electrical functions working intermittently
- Signs of heat damage or melted sections
If these symptoms persist after checking fuses, batteries and grounds, the wiring itself is the next thing to suspect.
Installation Guide
- Disconnect the battery before starting work.
- Take photos and label connectors before removing the old harness.
- Inspect the mating connectors for corrosion and clean them if needed.
- Secure the new harness with the original clips and keep it away from heat and sharp edges.
- Test all related functions before refitting covers.
Why Full Replacement Pays Off
Patching wiring takes time: tracing the fault, cutting, crimping and sealing, often in an awkward position. When the insulation is hardened along the whole length, that time is better spent fitting a new harness that solves every weak spot at once.
