I am putting an LO3(5.0 305) from a 91' RS into an '86 Firebird and I need the wiring diagram for one of the plugs. It is 15 pins total 8 on one side and 7 on the other.

Grey, Red, Blk/white, white/black, purple/blk, white, tan/black on one side

Orange, grey, blue, Orange, orange/blk, Purple on the other side.

The colors might be off shades since i didnt have good light. But it is the only 15 pin harness coming off the engine.

 

TTT... I need the diagram for the wire block going to the fuse block as well for both cars. Someone has to have these or know where to get them.
