I have a 75 88 royale the fuse box inside is completely dead. The fuse box looks to be in very good condition. I checked the plug at the fire wall engine side and it appears to melted when I disconnected the plug it looks fine no melty. I am assuming the wiring melted the outside of the plug. I still have dash lights head and taillights but have lost doors locks and windows. Bottom half ish of the plug is still work on the left and right side all other pins are dead. I need a wiring diagram if anyone has it, I cannot seem to find one on the interwebs, Thanks. Pics provided of fuse box and inside of plug coming from harness.
