I'm fitting an xt600 engine to a crosscart.
There's only one problem..
I don't have the wire harness..
I can make a new harness following the wiring diagram i have.
But the problem is that in the diagram it only shows what colour the wires are and not to witch connector and pin number...


So i wondered if there's anyone out there that could send me a closeup picture of the CDI unit showing the connectors and wires?

I'm not sure what model it is, but it's betwen -84 and -90 with el. start.

Near the engine number you should find something like 3AJ or 3VJ or 3TB please specify to understand better what motor is yours. a picture and the serial of the ignition unit could help too to identify your model

As has been said, knowing *exactly* which engine and ignitor you have is important, there's a helluva lot of different setups for the XT engine. For starters, there's models with CDI, that you can happily run without battery, and models with TCI that will require a battery to run.

If the wiring diagram you have doesn't make sense for the colours of the wires coming out of the bits you have, then there's a good probability you have the wrong diagram, which won't help...

For example, I've attached a snip of the wiring diagram for my XT550 (it's labelled in Italian, but hey), from which we can see not only the colours of the loom wires (B/W, O and B from the CDI, the rest are component to component interconnects), but also the colours of the wires coming from the CDI itself (W/G, G, W/R, Br, R, B/W, O and B). In this case, we can see that I would need to connect green to green, white/red to white/red etc. It also shows the plugs, sockets and bullet connectors, as well as their genders - we can see that the sensor coil connections from CDI to alternator have a female CDI end, male alternator end, and that the red and brown (ignition source coil, FWIW) and black connections are male bullet connectors at the CDI end, whereas black/white and orange are female at the CDI end.

Exact wiring diagrams are available from various places on the net, but we'd need exact references to point you to the one you want.

The engine is marked with 3AJ00. I don't have the ignition unit.. I will have to get a new one..
Out of the engine there comes 6 wires.
From stator (3 white)
Neutral switch (1 skyblue)
And 2 wires from the pickup (blue\yellow and green\white)

It's not much to go on but so far it matches the diagram i downloaded from smokin' lizards.
