OK.

Power flows to the MET fuse as follows:

1. 80A MAIN fuse on positive battery terminal
2. 50A R/I Fuse
3. Contact of IG2 Relay

IG2 relay coil power flows as follows:
1. 80A MAIN fuse on positive battery terminal
2. AM2 Fuse
3. Power enters ignition switch connector on white wire (AM2)
4. Pink wire on Ignition switch connector (IG2) feeds the coil

I missed the R/I fuse when I was looking before. Check him next, and if it is not him follow the two flows above.

Ok. I'll check the chains of command. Ok. Found the 50 amp R?I. A red single.It takes a real wiring catastrophe to blow a big fuse, so I sure hope it isn't blown.

edit: It's good. I'll go through the others tomorrow.
