Turn key nothing happens

Sure sounds like a new neutral safety switch is needed. I think it is normal for all accessories to go off when the engine "should " be cranking.

Okay. So I am going to try and bypass the neutral safety switch for the time being. This will also let me know if that was the problem. Is it as simple as unplugging the 2x2 neutral safety switch from each other and plugging the two ends already in the car to each other? (To be more specific. Plugging the blue male/female end already in the car to the red male/female end already in the car. By already in the car I mean the to cords that connect to the neutral safety switch if it was connected.)

I hope this makes sense.

When I had my C4 transmission I had the neutral safety switch on the transmission shifter at the floor. I only had one wire that ran to and from the switch so I am not much help here. But I did remember we had a post about this from before. It was called..
Where is the Neutral Safety Switch? It was queried back on 05/07/2013 in the tech talk section and had some good information in it. Not sure if it helps. Larry

And my 63 is a completely different animal so I can't look at it for reference. From what I can tell that switch does both the neutral safety as well as back up lights so there is likely more to the wires that meets the eye. You will need to get advice from a wiring diagram or form someone with a newer car than mine.

The neutral safety switch wiring enters the firewall and goes to a two wire (one male, one female) connector that plugs into the main dash harness at or near the main firewall connectors under the dash.

The neutral safety switch wires are red with blue trace wires. Because you have the combined connector you'll have to make a jumper. Earlier individual bullet-style connectors you simply unplugged the two blue/red-trace wires coming from the switch and plugged the male connector into the female connector on the main dash harness side (jumping the switch side does nothing). You can't do that with a combined connector and Ford had a pre-made jumper for manual transmission cars. Once jumped you will not have the switch keeping the car from starting, if that was the case.

Here is what you may also see.

The neutral safety switch plugged into the combined connectors (along with the backup light wires) and then they fed it into the firewall (grommet part) and then you had the individual male/female bullets. That would make life easier, but if you have the two combined connectors under the dash, you'll need to make a jumper.

Note also the neutral safety switch on the transmission has the backup light switch built into it too, so you will see two pairs of wires from the transmission mounted part.

Good luck (following my destructions) !
