Fusible Link Fried!

Went to the hardware store turned the key and no start, tried again and POOF, and big cloud of smoke came out at the fender and hood. Completely fried the fusible link. Towed it home and installed a inline fuse while I try to trouble shoot it. Works fine till I put the key into the start position and pop there goes the fuse. Have tried unhooking every thing electrical one thing at a time and still can't figure it out. Unhooked and tried starter relay, coil, distributor, ecu harness, even the starter. Prob more things I can't think of right now. Starting to suspect the ignition switch but thought I would reach out here first before tearing into it.
