OK here we go. I have a 1990 Camaro I'm trying to install some fog lights, I have a wiring harness not sure what year its from. At the switch there are 4 wires yellow,purple, grey, and black. I confirmed that the yellow wire goes to C2 and the purple goes to C3 on the c100 terminal. I'm assuming the the black is ground and the grey powers the light on the switch. The wiring harness has one red wire with a fuseable link (constant power) which should go through the firewall and connect up to the fog fuse, unfortunately there is no connector for this wire. On the fuse block there is a red wire going into the fog fuse and a light blue (or white, hard to tell) this goes to A1 on the c100. I guess I'll have to tap in to the red wire going into the fog fuse. The relay on the harness has 4 wires going to it, the red (fuseable link), green, black, brown. I believe I have to connect the brown wire to c3 and tie in to the brown wire on the marker lights and the green to c2 and tie in to the high beam green wire. The wiring harness has purple and black wire going to the fog light connectors as well these wires go to a connector which is supposed to go through the firewall and connect somewhere. I have no idea where these should connect, there is no connector under the dash for these. Any help would be appreciated.

Thanks
