Hey guys I have a question on what appears to be an oddity in the color reference on the schematics on my EBD that I am working on.

So can somebody cross check me with what I think is something amiss with color coding.

I will start with a comment that I replaced wires one at a time to the new connector and followed the schematics and cross checked each. The plugs were pretty jacked up though.

My question is with A9J1 (Aux Lamp Driver Board ) and specifically pin 7. The schematics say this is color code 65 which is brown white. You can see from the photo of the original that the wire in pin 7 is blue yellow.

Pin 7 goes to A5J4 pin 6 which is a 23 also blue yellow. This then goes to A4J1 pin 17 another 23 (blue yellow). I have attached a few pictures of the original connector the schematics and the final work. To me it looks like the schematics for A9J1 pin 7 are wrong? Am I missing something?

Thanks

Dave

Looks like you found an error in the Aux Lamp board wiring schematic.
The lamp "PD1" signal is marked as a blue-yellow wire at the MPU board and lamp driver board. So the PD1 signal at the Aux lamp driver board should be the same wire color.

Thanks Quench. That's what it looked like to me, but I wanted some additional eyes on it.
