help!! with wiring

[deputybob2004]

I need some help. I just put a new dash wiring harness in my 70 road runner. the under the hood side of the wiring harness has 3 sets of plug ins.
1 for the engine forward wiring(goes in the bottom plug)
1 for the engine itself(goes in the middle plug)
what is the other harness (top plug in ) for?
when I bought this car 6 months ago the gas gauge would not work,so i started back tracking from the tank to the dash.I shined a flashlight up under the dash and was surprised!! it had been on fire at one time and there were more scotch locks under there than auto zone stocks!!
anyway i have no idea what goes on the top plug in and need help. thanks from a guy who will NEVER buy another car on ebay unless I can look at it first! thanks bob

the engine forward /lights wiring harness is for all front lights and signals, and it plugs into the bottom of the female plug that come through the fire wall. the nest section (going up the female plug) appears to be for the engine harness. so the top plug or row of plug ins cant be for the lights. Could there be a plug in for accessories? there is not pig tail for the wipers on the engine/forward wiring harness. If some one has a picture of under the hood firewall that shows the wiring harness and what plugs into it, it sure would be helpfull. thanks bob

I dont have a photo, but my wiring diagram shows 4 wires in the lower section to be for the wiper motor. the upper side is unclear, but I'm gonna go with the neutral safety/back up lamp switch.

Here is a decent site for some basic diagrams.

The top row on my 69 Road runner was for the wiper motor and I believe the neutral safety switch plugged into it as well.

I remember because while assembling my engine bay, it was the first thing I attached and the first thing I broke, LOL
