2A. Resistor Pack
Labeled
3. Horn relay socket
Labeled
4. Power to Fuel Gauges. (red)
?
5. That yellow wire you tagged as wiper switch actually goes to the washer pump from the wiper switch.
No washer reservoir or pump, so I assume this will not be used?
6. Power for Voltmeter (yellow)
Labeled
7. Power for Oil Pressure Gauge (red)
?
8. Sensor for Oil Pressure Gauges.
Labeled
9. Sensor foe Fuel gauge (Pink)
Possibly Labeled? Had it noted as manual transmission jumper??? But it is pink
10. Sensor for Temp Gauge (Violet)
Labeled
Ok here is what I have come up with on my harness. Still missing some things but I think I'm getting closer. Please correct me if I'm wrong on any of my labels. Highlighted wires are my current unknowns.

labeled-harness.jpg

Highlighted in green is the yellow/yellow and red/white plugs that are used for auto tranny, again assuming these will not be used anywhere in my setup?

Highlighted in purple are the two red wires coming off the quadratac light, seems these about line up where the oil and fuel power leads would be needed?

Highlighted in red are the other unknown red wires one with a similar plug to what the ilumination plugs use and one with the non stock connection on it.

Highlighted in Blue is a plug coming off one half of the ignition plug with two blue wires

usually there is a ground also with the Power to the Cigar lighter. But I didn't separate the harness. Here is my Cigar lighter connector.



That courtesy light can be the ones under the dash or the dome light if you have a hard top.

Yep won't need these.

Could be. Look closely to make sure one of them is not pink.

Pink is for the fuel level sensor.
Purple with a trace is Temperature sensor.

Oh Boy, good luck with this one....





Quote:

NSS (Neutral Safety switch) overide. Should be a jumper between the terminals. Don't need this one either

Three unused terminas if you have a manual tranny.
From left to right... Kickdown switch for automatic transmission, Neutral Safety Switch, Back up light Switch








Not sure about your Oil pressure sensor label. Is that added? it should be solid purple.







Wiper power looks right.

I don't think the fuel sensor as labeled comes out there....






Here is a Hi Rez. 79 Schematic I merged together that you can zoom in on really far for detail
Just the link or it will take a long time to load into the post....

Great, that eliminates a few unknowns. I will just have to leave most of those reds unplugged until I can get the harness mounted and have juice running to it.

Did you see the note I posted in the last reply about the pink wire that I had labeled as manual transmission jumper? That is the only pink wire in my harness so I'm going to say that is the fuel sensor.

And last but not least just so I am clear, there is no distinction between a red switched power wire and a constant power wire? Also where would I want a constant 12v?

Last comment, there is a difference.
Constant power for:
4 way/emergency flashers (red/t).
Brake lights (Red/t),
Dome light/courtesy lights power (forgot about that one) (Orange?),
Clock power (White),
Park/tail lights (White to headlight switch)

Everything else switched power.

Looks like most wires, red with trace, is un-switched but only about 80%



Yep, Pink is fuel sensor.


Note: I added more info in my post you quoted you may of missed....

The fuel sensor in the overall picture is coiled up a few times, it is very long and I'm assuming before I spread apart my harness it came out further down the line.

The Oil pressure sensor is stock, just not showing very purple in the overall picture. Here are the temp and oil pressure wires...

John, I really appreciate all the help you are providing on this. From your above comments on non switched power, I don't see any that are solid red. Again I am assuming here but it appears that all these solid reds I have would be switched. If this is the case they really can be used for anything, correct?

Depends what size fuse its connected to in the fuse box.

You would not want to connect the power for the gauges (3 amps) to the heater switch (25 amps).

Don't forget you still need to figure how to supply power to the brake switch. Either find a constant power line that is hot and splice it in or fix the old power line and splice it back in. It could of been the old fuse socket was corroded and didn't make contact or simply the fuse was blown and he ran a new power line to the brake switch.

One final drawing I made up this morning.

It's for an 80 fuse box similar to 84 on fuse box but the TS flasher would be seperate.
Has a couple more wires than your 79 box but close enough.

I think with that last picture you posted I should be able to just go back to the source. Do you recommend any particular way to clean up those connections?

Also one more question... Right now let's assume that those 4 solid red wires are 12v switched power (which is what I need for my gauges) could I splice a few more wires onto them to make up the additional wires I need? Or is there a better way to go about that?

Best not to assume right now. Try to hunt down were they start by removing all the fuses and use an ohm meter or a continuity tester.

Backing soda usually gets the green crud off but rinse and dry it well.
