Hi guys, just to inform you that the Z works again !!! and i want to thank you all for the help provided

Now there is a new question:

In the 72 model, the fuse box is a short pig tail fuse box, it has 2 connector with 6 terminals each and 2 separate wires

Those 2 wire where do they go ?

Thank you all again

They have connectors and can only connect one way. One wire is white and comes from the battery for horn and stop lights(left one), The other is a blue with yellow stripe and goes to "common"(right one)

The blue one comes from the fuse bix and what does it connects?
