Hi,
I have a question which anyone with 3TJ can answer:
The 3TJ-00 ECU has 8 cables out, 1 becomes an one pin connector the other 7 split into a 3-pin and a 4-pin connector. Where are these go to the 3TJ *stock* harness?

Kind Regards,

Have a look at this

If you go to the grey bike front page there's a link to manuals there's an A3 size version there
