1962 ambassador wiring diagram (umbilical)?

[Hamb7]

We are trying to sort out some issues with our wiring. Tail lights, turn signals...etc. Does anyone have a wiring diagram for a 62? Thanks in advance...

The wiring is pretty much standard, through the 1970's. After that, the industry standard was changed, which may be why you are having troubles.
Here is a 7 pin plug, this is current, yours may be different, but will need to look like this to conform to your tow vehicle:

Airstream hasn't published its Bargman Connector wiring schematics for coahces built prior to 1964. It is quite possible, however, that your 1962 may have similar color codes and schematics to the '64. The link below will take you to the pdf file containing the 1964/1965 Bargman connector wiring. You will note that both the "Pin-out" pattern and color coding of wires varies from the standard utilized today.

Good luck with your investigation!

What are the basic steps for problem solving these issues. I guess one thought is to get a battery and use it to figure out which wire on the coach does what? We have...

red, yellow, green, blue, white, black, brown on the coach.

On the pin we have
red, yellow, orange, green, brown,white , black

Silly question, does it matter as much about the color on the pin or the position the wire is in in the pin? Does that make sense? I am wondering if PO put the wires in the correct spot on the pin.

I wouldn't count on what a previous owner may or may not have done -- neither of my coaches had Bargman connectors that were wired to match the current standard format that my tow vehicles had (and neither was wired precisely according to the illustrations on the Airstream site -- the wire colors matched their labeled functions, however). Both my '64 and '78 had the color codes matching those in the corresponding Airstream literature. The function of the wire is more important than its color, and you want to match the functions between the modern standard connector on your tow vehicle to the rewiring of the Bargman connector on your coach. Before towing, each of my coaches required new Bargman connectors to match up with my tow vehicle -- to insure that the correct wires found their way onto each terminal, I utilized my garden tractor's battery to check the function of each wire (you will need a pair of alligator clips on long, rather heavy wires to perform these checks).

Good luck with your investigation!

Here's a version I used on my vehicles. It may or may not match either of your vehicles. If you plan to tow a different trailer while still owning yours or if a different tow vehicle is used to tow yours, you should follow the current industry standard. Forget about the color of insulator wire, just make sure it works correctly.

What we have now is the wires coming from the coach with the old wires then a bunch of quick connects then it starts the new wires into a 7 pin device the goes into the truck. I think it is going to be a bunch of trial and error. But is sounds like we have all the parts we need.

You may need to find a way to combine the brake and turn signal wires. Some of the older Airstreams had separate wires for the brakes and turn signals.

As you can see in Brad's diagram, the brake & turn signals are now combined at pin 5 & 6.

If you want to maintain operability of the separate brake light, try wiring it to the CHMSL (center high mount stop light) wire.

"You may need to find a way to combine the brake and turn signal wires. Some of the older Airstreams had separate wires for the brakes and turn signals."

ok...clueless here would that mean somehow making the brake wire into two so it goes into each pin...???? I understand what you mean about the seperate brake light.

If your tailight is like mine, you will have a single filament bulb (running lights), and a dual filament bulb; one filament for the brake light and one for the turn signal.

If you combine the wires for the brake and turn signal, then when there is power the brake/turn signal from the tow vehicle, both filaments will light. You would need to do this at the rear, in the brake light assembly. Check the wattage and wire size.

There is no separate "pin" for brake lights from modern tow vehicles. See Brad's diagram.

The original connectors for my '59 were:

Six pin connector

• Red - left directional sig.
• Green - running lights, tail light, licence plate
• Blue - brake magnets
• Black - brake lights
• Yellow - right directional sig.
• White - ground

Three prong Twist lock plug

• Copper - hot 12V charge line
• Brass - ground
• 3rd pin - not used

Thank you for all your help everyone.
