The cables for an A1 will have longer connector on the light ends due to the turn signals being on the fenders and the blackout lights in the grill as opposed to the A2 where all of the lights are in one unit. Usually wiring for an A1 is substantially more expensive than for an A2.

All the turn signal wires are in the harness of an A2.
The harness you are describing is for an A1 only.
Time to fix what you have or replace front harness.

Does the turn signal cable for A2 be individually purchased? I'm looking at different stores on internet and I do not see it. I've only seen that for the A1. Have you ever fixed a connector of that type? I only have the problem in the A (460)

If you are talking about this harness than yes it will fit, this ties into the main harness under the dash. As long as your harness also has the plugs under the dash. The other option is to find the tool to remove the pins from the main plug and put them in the way they belong, or just cut and solder the wire in the proper order and cover with shrink wrap. That is what I would do, a lot cheaper than a harness! And if you do it under the dash nobody will ever see it. My question would be are you absolutely sure this is the case? Seems like someone went to a lot of trouble to reverse the wires. Check the plugs under the dash and possibly reverse them or put them right more likely. I have rewired those connectors to serve other purposes way back when I did this as a business. I no longer have the tools. The harness from the turn signal should go under the dash and meet the main harness in a set pf plugs, especially if it is an early harness. Check that first. You may just have an issue with the one plug.

Those main harness plugs are called Amphenol connectors.

As I said before the A1 turn signal cable is a separate item. It plugs in to A1 main harness.
Those wires are a part of the A2.
I may have a cut off connectr if you want one:

Ok, I see the confusion, you have an A2. I was thinking A1. I don't see how those wires could possibly be reversed unless someone cut and spliced them back together that way. Have you followed the harness from the signal down to where it goes into the main harness to see or feel if there were any splices? When you put power to the 22-460 wires at the E terminal do the right front or rear lights come on? f the rear lights come on then if you turn on the right turn signal and check the corresponding pin is the flashing voltage there? And you did not say what happens with the four ways on.

hello.If I connect 24 v on the 460 cable to the connector output the light bulb works well. if I connect 24v in the connector but in the part where the control is plugged thetenis a short circuit and spark occurs.
I have tested with two turn signal control and with both happens the same.

When I put power to the 22-460 wires at the E terminal , right rear lights come on well with flashing. When I connect four lights with the control,all lights work well less front right

Hi Fil,I’ve sent a pm

Ok, So that means if you put power to the 460-A terminal you should get lights at the right front but they are not working? If they are working when you put power to that terminal then the wiring is fine and there is not need to change it, the fact that the 22-460 lights the right rear pretty much verifies that the wires are not reversed.

What it boils down to is this, If you put power to the A terminal of the plug and the right light does not come on then the problem is in the wire, or the composite light assembly. Those lights had a lot of problems with internal corrosion. If the lights do come on then the wiring is fine and the problem is in the signal unit. Just because it is new does not mean it is good.

If I put power directly into A a shortcircuit occurs.

If I put power directly in 460 wire ( I have cut it and separated it from the connector ),right front light get light

now I have plugged the connector (wire 460 cut) and all the lights work fine less le front right

Well, You have isolated it down to one connector, this is good. It is entirely possible that the letters on the connector do not match with the letters on the signal unit, that is why I was also referencing the wire numbers at the same time.A could be a ground. What you can do is a continuity check from the cut wire at the back of the connector and see what letter it is in the connector. I am going to get into the manuals further and see if I can determine what the A terminal is and also what terminal the right front uses plus the full path for that circuit. Give me till this evening.

I am still working on it, The -20 manual has no description of the connector and the -34 has no electrical section at all!? I have to dig through my hard copies but I think what I am going to do is go out to my A1 tomorrow and see what the A terminal goes to. It is going to be a little easier for me if I have eyes on the vehicle. I don't think the problem is going to be in the harness, I think it is going to be in the signal controller.

I listed the connections earlier in this post. If I had to guess I would say that the connection inside the plug is faulty and the wire connected to A is somehow earthing

That is what I thought Howard but there are no grounds in that harness according to the diagrams. And although the connector is metal it is on a fabric wire, so again, no ground (or earth) there either. I am going to check the resistance of my A terminal and see if it is a dead short or shows resistance consistent with light bulbs.
