Blowing #4 Fuse/ No Tail lights, Cluster, Parking Lights, License Plate light

All,

I'm happy to say that the problem has been resolved! Thanks for all of the input! Turns out that a ground that I had on the firewall for my fuel injection was causing the short. Removed it and voila! Addition by Subtraction! Now I have 100% functional lighting.

Thanks,
FABO!
