Electrical problems

[agh1989]

Hi guys. I havs a gs750 1982, the plan was to switch the original instrument ”brick” to new and more slim tach/speedometers.
i am quite bad at the electric part. But do you have to have everything connected or can you skip wires to some parts?
is the whole system connected in some way?
because before i took it apart, the lights worked. Now it wont.
it should be working with the engine off but key to ”on” right?
only light working is the parking light front i think. (The small light bulb).
sorry for the messy question, gard to explain when you dont know so much, yet.. trying to learn

From what I've seen with the modern instrument clusters - not all wires need to be connected.

However, connecting them right is a PITA.

If you can upload the wiring diagram for your unit I might be able to help.

I manage to connect the led strip right so the rear light and brake light are nog working when i bought the bike it has mini turn signals on it and i assumed it was led, with led relay allready installed. (Which is wasnt) just mini turn signals. no wonder my led turk signals was static and didnt blink..
so i am going to use the ”old” mini turn signals instead.
do you know which ground cable goes to the turn signals? I Will try to upload a image
