O2 sensor

[chavo6723]

I am looking for the fusible link on the o2 sensor that comes off of the ignition switch. I found the grey and yellow wire from the ignition switch. It's a 12 gauge wire with no fusible link. The schematics say it needs to have a 20 gauge fusible link on it which is odd. The 12 gauge wire goes to a connector then drops to 18 gauge wire that goes to the sensor. Looking for input on this.

Supposed to be on the driver's side inner fender. It looks like a piece of rubber in the wire.

I've replaced the whole wire from ignition switch to o2 sensor. No link. Just found it odd that it went from 12 gauge at the ignition and then 18 gauge at the connector where the link was supposed to be. I ended up adding a link in the end.
