873743 Wiring Harness | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta wiring harness for engines from serial number 2204215440 onwards, from the Cables and Fuses group. It weighs 0.748 kg and is listed for 1 application on TAMD engines. It supersedes 873552. Harness 873744 shares the same published weight but covers 16 applications across AD, D, TMD and TAMD from serial number 2204215440 onwards, so the serial break and the fitment are what separate the two, not the size of the loom.
