This is a common Ford problem. First place to start...Sounds like the 02 sensor wiring may have rubbed into the exhaust and melted the insulation over time. I would start there. You should have 4 sensors to check out.

If it was me I would crimp connect the wires back together first. You may have no further damage. Oh, and be sure to route the wiring away from the exhaust

Checked all 4 no melting, wires intact is there any thing else I should look for?

One thing I suggest you remove and inspect the back side of ur fuse box.....seems to be another Ford common problem. Here is a YouTube video for u to read and listen to. It may be helpful in ur analysis

this fuse #41 contols power to all four oxygen sensors, both EVAP system valves (vent valve and vapor management (purge) valve), the EVR regulator (vacuum) valve, and the PCM power relay

what you can do is unplug all of the components on this circuit, and if the fuse doesn't blow then, plug them in one at a time until it does blow. You should be able to narrow down the culprit this way. I would be highly suspicious of the O2 sensors, and the PCM power relay (The PTEC is an abbreviation for the engine computer.. or Powertrain Control Module). If everything is unplugged, but the fuse still blows you'll have to trace wires to find the short, or use a short finder to help you find this. This can be a real pain, so let's not jump ahead of things... you may simply have an oxygen sensor or a relay shorted out. If the fuse blows immediately, then this is almost always a dead short to ground. The evap valves and the vacuum regulator valve typically do not fail in this way (at least I've never seen it, nor heard of it happening). If you don't want to keep going through fuses you can purchase a digital voltmeter, set it to OHMS (resistance) and connect one lead to the fuse terminal, and the other lead to battery ground. Unplug things one at a time until resistance reads zero.
