But now you have no turnsignals correct?
well the fuse is continuing to blow even after that wire is deleted but even with the wire cut the hazards worked? not sure what wire i identified as "blue"

Obviously you can't read the electrical diagram above. If you need help with it, just say so. You can see the hazards are fed by a different fuse and are on the right side of the diagram.

I had a similar problem with my running lights. It would blow the fuse every time I powered the head lights or parking lights. I checked everything and I found a LIGHT PLUB was shorted. This blew the fuse. I spent two weeks looking for shorts, rubbed raw wiring, or anything else that would blow a fuse. Check every bulb for shorts!

how do i see if a bulb is causing a short? just corrosion?

Your hazards use the same wires and the same bulb filaments as the turnsignals. So theoretically the hazard fuse would have blown if there is a problem with the wiring going out to the lights and the bulbs.

If you had cut the correct blue wire, your turnsignals should have stopped working. When you press the brake they would have both lit up in the rear, and then moving the turn lever left or right would have made one of the rear lights go dark with the blue wire cut. And the front turns would have done nothing.

If you did cut the correct blue wire and it still blew the fuse, I would investigate the reverse wiring some more.

oh that makes alot more sense, also i have no clue what the blue wire i found was it wasn't a turn signal wire
will do on the reverse light wiring i can confidently say trans back is ok but unsure about the in-cab portion

The light bulb died and caused a short between the + and - of the light. This caused the fuse to blow. This is the first time I have seen this and I am an old guy.

It appears the output for fuse#5 is actually purple and orange

That is correct. That is what the diagram shows. Once it goes through the flasher, it then turns to a blue wire. The flasher is mounted to the fuse box correct?

And that digram shows a bronco I know the wiring changes color over the years of the bullnose

Sorry, I picked the wrong diagram. You can see it's the same in the front, just the rear wiring is a little different.
