Wiring Diagrams

[my1stgn]

Anyone have any wiring diagrams for the lights and ECM? I downloaded the ones from GN TType but when you try to zoom in they get blurry so its hard to see wire descriptions. Im trying to install an alarm so any wiring diagrams would be awesome! thanks!

Could you be a little more specific as to which lights? I'm assuming exterior lights, but........

I've got all the wiring diagrams from the factory service manual at the house. You can borrow them, make copies or whatever....

I'm going to qualcomm this friday. If you're going there I can bring them if you're not in a hurry.
