• Designed to handle higher current loads without deterioration

Is installation difficult — will this work as a plug-and-play replacement?

Installation is intended to be straightforward since each harness is a direct replacement for the factory part. The harnesses come with the correct pigtail count and connector types so they mate with the existing door modules and body harness without splicing in most applications.

• Supplied as two harnesses: left and right rear doors
• Each harness includes five pigtails (1 male, 4 female) to match factory connectors
• No cutting or custom wiring required when matched to correct OE number
• Follow vehicle service manual for door panel removal and connector verification

What should I check before buying to make sure the harness fits my truck?

Confirm the OE part number and your truck’s model year and trim; door configurations and wiring options can vary by equipment level. If possible, compare the old harness connectors, number of pigtails and wiring routing to the product images and OE list to avoid returns.

• Compare OE numbers: 56051694AA, 56051931AA, 56051931AB, 645-506
• Verify vehicle make/model/year and rear door type (driver/passenger side)
• Check number and gender of pigtails against your existing harness
• Inspect connector shape and mounting point locations for match
