The fuse panel diagram you included is found under the dash, but the slot for the turn signal flasher is empty, as is the hazard flasher. These two cylindrical relays are not present anywhere. The combined turn signal/flasher relay is just behind the dash, slightly to the right beneath the steering wheel. I know for a fact that this is the turn signal relay because we have made the turn signal work by playing with this relay. Please read a previous post from me with the exact same title as this one. In it I explained all of the troubleshooting that has gone on so far and I've tried to explain that the fuse/relay diagrams in the Jeep manual and in maintenance manuals are NOT what is seen in my Jeep. I can provide photos if necessary.
As for gerry-rigged wiring. Once upon a time there was an anti-theft ignition kill device installed. However, this has been completely removed along with all its associated wiring. There is trailer lighting, but it was professionally done and I would not be able to recognize any of its wiring unless you told me what to look for.
If you consider what we did while testing the relay (please refer to previous post), it's really pointing toward some power delivery to the flasher relay. We could jump two leads and cause the TS to work. I'm attaching two wiring diagrams. Please look over these and note the hot connection from the ignition switch. This is what we suspect is the problem - that the flasher relay is not getting its operational power from a hot lead.
