2003 C4 Connector pin-out? (front light harness)

[Bob H]

I went through the TSB forum LB7 and LBZ sections. I was able to find the C4 connector pin-out for the LBZ, but can't for the LB7. This is the green plug that goes into the underhood fuse box and goes out to the headlights/DRL, turns, fogs, horns, etc..

In short, trying to chase down a DRL issue after I swapped in a LBZ. I lost my DRL but have everything else and I've been troubleshooting for over a year, and I'd like to see if there is a difference btwn the 2003 C4 plug and the 2006 C4 plug.

Any help or links is greatly appreciated!

The LBZ link is below, I need a similar one for a 2003 LB7.

I can only find one for a 2001. Don't believe that is the same as a 2003.

Thanks!

I'll post a link to it in my OneDrive in a bit.

But I do have it.
