My turn to ask for help - GM wiring color codes
I have a project I'm working on, and I have all the factory manuals.
It MUST be in the volume somewhere, but in my impatient 9 and a half mins, I couldn't find it.
Here are the codes I need the mappings to, and my edumacated guesses (although what I am after is a master reference chart to validate and have it handy for future projects).
L-BU = Light Blue ??
D-BU = Dark Blue ??
BN = Brown ??
TN = Tan ??
D-GN/WH = Dark Green w/ White stripe ??
D-BU (on another connector) = Dark Blue ??
Thanks in advance!

Thanks erick_e - looks like my guesses were correct.. Why they didn't place the abbreviations for the wire colors in the wiring section is beyond me.

I have a project I'm working on, and I have all the factory manuals.
It MUST be in the volume somewhere, but in my impatient 9 and a half mins, I couldn't find it.
Here are the codes I need the mappings to, and my edumacated guesses (although what I am after is a master reference chart to validate and have it handy for future projects).
L-BU = Light Blue ??
D-BU = Dark Blue ??
BN = Brown ??
TN = Tan ??
D-GN/WH = Dark Green w/ White stripe ??
D-BU (on another connector) = Dark Blue ??
Thanks in advance!
