Turn signal switch wire identification

okay now that Gary helped me with ignition diagrams, i need to determine what each wire in the turn signal switch goes to. Anyone have a diagram that says what each color wire is?

I would say yes. It will be obvious most of the time when something is amiss and doesn't jive with the diagram as you are going through the wiring. There is a 1981 EVTM on Gary's site also, so between the two you should be good.

What Franklin said.

The 1986 version should be mostly correct for a 1982 with a few small differences.

- Someplace around 83/84 Ford added wiring for a key-in-ignition buzzer, that's in the 1986 version.

- Somewhere in the mid-80s(?) they stopped using hashes & dots as the tracer colors on the wires and used only stripes.

You never gave us any specifics as to year & configuration of what you're working on so I just chose a manual from Gary's site *****-nilly but yes, there is also a 1981 version out there and that one might be closer to what you actually have on your 1982.

After looking through the manual I am still confused. I can't find anything that correlates the color of wire to its function. In the picture below, I need to know what each wire goes to. Reason is, the harness I am installing is not colored the same and I want to make sure I match each wire up correctly. I am sure I am missing something simple, but I can't seem to find the info I am looking for.

Lightblue is the turnsignal flasher coming into the switch.

Orange/lightblue is the brake/turn going out to the rear pass side light

Lightgreen/orange is the brake/turn going out to the rear driver's side light (you have that as a green/red)

White with red hash is the hazard signal coming in from the hazard flasher. The diagram shows this red/white hash, and then shows it white/red hash.

The yellow has lightblue dots on it( I can see it in the picture). This is power to the horn

I need to go, I can get back on it later. I am using the diagrams in this link Lights: - ???Gary's Garagemahal and this link. Horn, Speed Control, & Cigar Lighter: - ???Gary's Garagemahal

The key to the whole thing I found out, the connector you have in the picture is c305. So anywhere in the diagrams c305 shows up, there will be one of your wires.

Darkblue is also the horn

White/blue stripe is the front pass side turn lights. There is a double wire because one goes out to the front lights, the other goes up to the cluster for the indicators in the dash.

Lightgreen/white is same as above, goes to the front driver's side light and also goes up to the cluster dash indicator.

I can't find the two white/red stripe wires.

lightgreen is the signal coming in from the brake pedal

Wow,
Thank you very much for helping me out with those. I also cannot find the two white/red stripes, but can now see where you got the others from.

As you can probably tell, wiring is not my field of expertise.

Apologies for jumping in on an old thread, but I was wondering if anyone has a link for a turn signal switch that matches the above image posted by Gigemags05. I have been unable to find one.

I have a 1983 according to the vin, but the wires on the 1983 part and harness don't match the female 305 connecter on my bronco. There has been work done that was not mentioned when I bought it, including swapping out the straight 6 for 351 windsor, so it's frankensteined some. I'm tired of banging my head against the wall and figured I would try here.

If you can tell in the pictures below, i have a light blue / red stripe where there is nothing on the picture above, and nothing where the two white / red stripe wires are. The parts store swears its the right one, but clearly something is amiss.

This is a 1985 switch testing diagram. It has the 1985 plug diagram for the turn switch.

This thread may be of some assistance, especially the labels in post #20:

https://www.ford-trucks.com/forums/1...ing-guide.html

Please note the various color codes Ford used really only applied to the vehicle harness. The wires between the switch itself and the big quarter round connector? Those are vendor supplied. For all we know, a vendor could have supplied them all in white or pink or chartreuse. The only aspect which matters is what is connected at the end of each wire.

At the time, Ford may have specified OEM parts would follow a specific color code. But aftermarket parts 40+ years later? "Hey, we've got all this white wire so lets use it up."

The moral of this heart-warming tale? Don't rely exclusively on color codes for any vendor-supplied wiring.
