Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

For a 2002 C4 Cab, is there any pictorial or schematic of pin assignments on headlight-to-body harness plug (where the harness plugs into the receiving plug in the headlight cavity inside the fender)? Specifically, I am trying to determine the power and ground pins for the Left Front Turn Signal Light. I have the Bentley Manual with wiring diagrams which are in black and white, spanning multiple pages, and are hard to decipher. Thanks.

Hey Bahman - hopefully the attachment works and helps? I use a program called BlueBeam (on my work laptop) to highlight/trace wiring circuits

POST 4 / ORIGINAL POSTEROriginal post

e30rapidic , Thank you for the diagrams. Very helpful. I was able to identify the power and ground terminals on the female harness plug. The left turn signal functions correctly up to the harness plug terminals. The bulb holder and bulb function correctly, but do not function when inserted into the respective receptor in the headlight assembly. The problem seems to be either the spring terminals which touch the bulb holder, or the wires form the pin at the male plug to the terminals at the bulb holder. Will try to diagnose next few days. Thank you again.

This is a source reference. Confirm exact model applicability in the original material.
