new to me 1971 sovereign. now to get it home

I just bought my first AS, a 1971 airstream sovereign 31. It has been in the family since new I believe. I paid $750 i hope i didn't overpay lol I am about to bring it home and I need to change the trailer light plug to the modern 7 pin plug to match my pickup. Does anyone have a year specific diagram for the lights? I have seen a few but every one is different. also I have heard of a service manual, where can i buy one?Click image for larger version

This Wiki page might help... I would go to the trailer with a voltmeter, some jumper wires, a new cable that fits the truck, with modern connector and wiring/color conventions, and then test and wire each connection on the trailer individually. First determine which pin on the trailer is ground, using the ohm function of the voltmeter; then connect the negative of a test power source (a spare 12V battery) to the ground pin and use a 20A fused wire to test each remaining circuit and wire the connector accordingly. Finally, test it with your truck, before going anywhere.

I am planning on taking my Power Probe which I can test each wire with. I was just curious if anyone had the diagrams. But anyway I will just test them all, shouldn't be too hard to figure out which is which. The power probe has a breaker in it to prevent any shorts etc and I know which wire is ground on the trailer. If you are unfamiliar with the power probe tool I'm talking about, look them up on the web. I would recommend anyone who works on dc power to have one. I do classic muscle car restoration and I use mine every day.

Well with your power probe you can identify your circuits in about five minutes.

I have one, it is a great tool for electrical troubleshooting, just behind a volt and polarity sensing test light imho.

Brevi tempore!
The fact that I am opinionated does not presuppose that I am wrong......

We purchased a '71 Sovereign a few months ago. For $750, I think you stole it. Lol

I have the original owner's manual that came with the trailer. Here is a scanned copy of the 7 pin plug.

I made it home with the as

I made the trip home yesterday with my airstream after servicing the wheel bearings and installing new tires. I got the trailer lights wired up to a new 7 pin plug. I took everything I thought I would need to get the lights working. I was wrong. The screws in the tail lights are so rusted I couldn't get them out. with no drill or bits to remove the old screws and knowing that the cracked lenses would fall apart as soon as i took them off, I decided to forget about the lights and have a buddy follow behind me.

So now I am trying to decide where to start. First off could somebody explain rear end sag/seperation? How do I know if I have it?

The blue carpet needs to go and I have hours worth of cleaning to do! Then I plan to start testing all of the major systems.
