Electrical problem
1994 GMC Safari 6 cyl Two Wheel Drive Automatic 189700 miles

I'm replacing the fusible link connector at the firewall. I got a little ahead of myself by removing the connector. Now I have to figure out where each of the fusible links go. There are (2) 2.0 SQ MM and (2) 1.0 SQ MM going to 4 red wires. One is easy. It goes to the blower motor. Another I can trace to a unit(?) Mounted on the firewall below the brake master cylinder but I don't know what it is. Maybe the ECU? Two go inside to the fuse block. My question is which goes where? And is that unit under the master cylinder the ECU?
