What do each of the 13 wires innervate in this E39 trunk lid wiring?
Is there a TIS on this apparently common wire-chafing problem?
The reason I ask:
- To improve our DIY procedure: Many of us have chafed or broken wires, which seem to enervate various lighting and latch components; many of us find out only because of weird trunk or lighting electrical problems; if we knew which components were innervated from this wiring harness, we could better build a DIY diagnosis of where to look for problems in the future!
EDIT: These electrical gremlins are known to be related to the trunk loom wiring harness:
- Trunk latch problems (not working, intermittent, weird behavior, etc.)
- License plate light problems (especially one and not the other)
- Trunk light problems (especially intermittent, fuse blown, or no power)
- Central Locking (ZV) system problems (of which there are many)
- Fuses blown related to the trunk latch, door locks, or tag lights
KNOWN LOOM WIRE CONNECTIONS:
01. Red/yellow line = 2 @ x712 -> trunk lid light (positive)
02. Red/black line = ?
03. Gray/yellow line = 3 @ 1377 -> tunk lid locking switch (open signal)
04. Brown/gray line = 2 @ x709 -> left license plate light (positive)
05. Gray/Brown line = 4 @ x311 -> zv drive (lid closed)
06. Gray/black line = 2 @ x710 -> right license plate light (positive)
07. Gray/Green -> 4 @ x311 -> zv drive rear lid (positive)
08. White/ Brown line = 3 @ x311 -> ZV to luggage compartment light
09. Brown = 1 @ x709 -> left license plate light (ground)
10. Brown = 1 @ x710 -> right license plate light (ground)
11. Brown = 5 @ x311 -> zv drive ground
12. Brown = 1 @ x1377 -> trunk lid locking switch (open signal)
13. Brown/blue line = ?
NOTE: (majority color)/(line color)=(pin number)@(connector number -> description
