7 wire brake light switch how to tell which wire is which?

I am having a problem wiring up my 55 with a 7 wire turn signal switch with a new signal stat 900. The main problem is that the switch that was on there was totally inoperable and thus I am starting from scratch. I don't have any idea which wire coming up from the wiring harness is which. It is a stock harness, or very old as it has the cloth looking wires. I searched here and thought I had figured it out by looking at this link which shows the circuit board of an older sparton switch:http://www.jeep-trucks.com/index.ph...rical&part=turn_signal&action=spartan&step=14

That didn't help, my old switch is actually an auto lamp 9000 and so I tried this wiring diagram:
http://www.hotrodders.com/forum/autolamp-9000-wiring-217114.html

That didn't do it either. All I have been able to get so far is both front turn signals to flash when I am trying to turn left on the new switch. Is it possible to put power with a little battery or power probe on the end of the wire under the dash and then check at each individual corner to see if there is power there? Does this make sense? I am not an electrical whiz by anymeans. Any ideas, I don't want to open up my wiring harness or anything crazy.

Thanks everyone.

 

That's what I would do. Apply 12 volts to each wire and see which bulb lights up. Connect them accordingly.

 

old school electrics 7 wires . 1-left front turn 2- right front turn 3- left rear turn 4- right rear turn 5- brake light switch wire 6- flasher 12V hot 7- indicator light (ground)
I would test each wire with 12V and see what lights up . brake light is internally switched . and 12V flasher would be only hot wire .with ign switch on and that one would flash if grounded

 

See if this comes close: http://www.film.queensu.ca/CJ3B/Tech/SignalWiring.html

Or this: http://www.stovebolt.com/techtips/turn_signal.htm

Both show wiring for the 900. (stovebolt.com is clearer)

 

I thought I would post a follow up thread. To reiterate my problem was I had a broken 7 wire turn signal switch, so I had no way of knowing which wire did what coming up from the harness. My switch was an old autolamp 9000 model. I first took it apart and tried to figure out what wire was soldered where inside the switch but I couldn't come up with a picture of the inside of the autolamp 9000. I could only find this link: http://www.jeep-trucks.com/index.ph...rical&part=turn_signal&action=spartan&step=14 , which is a 7 wire unit with a circuit board similar to my autolamp. Although it looked the same it was a no go when I hooked it up. Then I decided I needed to apply power to all 7 wires and trace them out to figure out :rt front, left front, rt rear, left rear, stop light switch and the other two going to the flasher. I ended up buying a powerprobe 3 to use to apply power although you could do it with any wire hooked to a 12 volt source. The power probe allowed me to do this pretty easily. One reason I am updating this is in my research I ended up getting more motivated to learn about auto electrical. I found a great series of you tube videos by Dan Sullivan http://www.youtube.com/channel/UC_WCJS2QvK0TKs3xPjLgUzA
I found these to be very informative and I learned a lot about automobile electrical. It also made me realize I would like to get the tool Dan invented called the load pro. It allows you to do voltage drop tests with your meter and rule out shorts and opens. The value of this tool is that you are doing voltage drop tests on a live circuit and not a static one, thus it allows you to see a voltage drop, which indicates resistance like rust or bad wires, and chase the problem quickly and accurately. Pretty cool tool. Dan also makes a book which is apparently very easy to follow and understand as far as common auto electrical goes.

I found the following links helpful to understand the 7 wire switch:
