Default Question about Wiring Schematic

I'm trying at add fog lights on my FRC and for them to function like they were factory installed but I am unsure if my car was pre-wired for them. I started to look at the fog light wiring schematic to see what wires I am working with and I'm unclear how to read some parts of it. So far I have confirmed that all the wires are in the correct location on the BCM and the ORN, ORN/BLK and YEL wires are in the trunk release socket; but not the purple. Moving to fuse block under the hood is where I get confused...



Here are my issues:

            Can someone clarify these issues for me? And any input from guys who have walked this path would be great!

            Here are my issues:
              To the left is the wire diameter(gauge), to the right is the ciruit designator.
                Not that I've see. Bill may have one, since he disassemble a C5 in his backyard
                  Pin D1, is in connector C2
                    "L" usually means "line or feed". I'm stretching with "J" as "junction"

                      Actually, in this schematic, there are two purple wires in connector C3. One at pin C1, and one at pin E4. Also, one purple wire at pin D1, connector C2.

                      Can someone clarify these issues for me? And any input from guys who have walked this path would be great!

                      One more question; how should the wiring be laid out @ Fuse 6 with the PPL wires?

                      The way I understand the schematic is that the PPL wire from the switch runs out to the engine compartment and ties in with the PPL wires, for each fog light, and all 3 wires going into one (1) pin for Fuse 6 and the other pin runs a wire into the pin for J2 on Relay 39.

                      Is this correct?

                      All the purple wires terminate at the underhood fuse box. The fuse box is represented by a dotted line. Everything that resides inside the dotted line box, is an internal connection. Internal to the fuse box, the load side of fuse #6, is bussed to D1 of C2, C1 of C3, and E4 of C3. So no, they all do not go into one pin, rather, the purple wires enter the fuse box at 3 separate pins. The connection between the line side of fuse #6 and J2, is an internal connection as well....within the fuse box.

                      I added FOG LIGHTS to my 02 Z. All you need to do is purchase the dual switch and plug it in to the connector that the single switch is connected to.

                      All the wiring UP-TO the under hood fuse panel is there. The relay and fues was even there on my car. All you need to do is connect a single wire to it to go to the fog lights. I used ONE wire from the fuse box that branched off to both fog lights. I grounded the lights to the frame

                      Its been a LOOOOONG time, but,,, I think I spliced fog light supply wire into the purple wire out of D1. I will have to go back and look.

                      I got the clip nut for the mounting bracket at NAPA.

                      I do not have the PPL wire at the switch show in the schematic so I want to varify the fuse block pinout to see if I am missing other wires. And I am still unclear on how the PPL wires tie together at Fuse 6.

                      You will need a meter, to check the reistance betwen the connections at the fuse box connectors, relay socket, fuse, etc. You cannot see the internal connections, as I explained, all connections in the underhood fusebox( in the dotted line area) are internal....you cannot see them. That's why a meter is required to verify.

                      Ahh, so all the connections inside the dotted line are interior. That clarifies my issue.

                      Now I just need to know where the PPL wires plug in. Is this an accurate depiction of the pinout for C1, C2 and C3?

                      Correct. Below, is a view of the fuse box, looking from the bottom.
