The 1st is easier I think. Black wire coming from some firewall mounted plastic connector. The other wire in is thick and red. It has what appears to be a connector for a tube style fuse. Has round black rubber on the end. Round metal connector on the inside. Hot at all times.

2 is a light blue 18 gauge wire that comes from the c100 b2 slot and is hot in run.

84 z28. These are factory wires. Please help.
