Check control compatibility

Hello guys,
A friend of mine is selling a check control from his TS Alfa (the one that was came out in orange) but the problem is that the symbols are in a different order. Will it work normally or will I have problems in reading the control?

Full disclosure, I haven't done this, but if I was trying to do what you are, I would probably just move the position of the wires that insert into the connector on the wiring harness. You can get the them out of the plastic piece pretty easily with a small screwdriver.

Do you have a wiring diagram? If so, you should know which wires at the connector serve which component. You can test the ARC itself with a ground (look where ground is in the previous step and match it up with the ARC connection) and 12v. Look which light is illuminated.

Again, I haven't tested this, but it is how I would go about it in your situation.

There are more than 1 Alfa Control systems that were put on the 75/milano.

They are not the same. Later 75s in Europe had a very different system from the Milano's. For example the famous modification that is talked about on this forum a lot doesn't work for a late 75 because it doesn't have that part. The computers are different, the displays are different and the connectors on both are different. The wiring is different too.
More fun stuff: for the later system there NO wiring diagrams available. Only for the earlier system. And that one is useless for the later system.

Also, parts of the system I believe works on 5v (not 100% sure) so don't go putting 12v on random wires. Its going to blow up stuff. Its also not always a + switched system, some things on it are switched with ground. Again, don't go putting 12v on that.

Only swap parts that look the same or have the same part number if you want to have any hope of getting it to work. For me the Alfa Control is the only piece of car technology that I have encountered so far that remains a mystery to me how it works and why sometimes it doesn't work.
