cos I may need some help.

good luck!

Na its pretty simple once you've torn those instructions up, where you taking the rev pickup from? i took it straight from the cdi so if your doing the same you might not need to alter it.

Here's a link to the manual ( PDF )

Maybe this will help

What is the cost of one? I am using a XT racing dash and it is ACE!! It does everything and then some.

i got one on my nc29.

before i got issues on getting the correct reading for the tachometer, as i have using my old harness which is really a headache of tracing the problem. so i used of winding the induction coil with wire to get the reading. honestly, the reading is bad.

now, i got a second hand wiring harness and ignitech cdi, tap the rev wire from koso directly from the cdi and the reading is magnificent!!!!

lesson learned, if you have a faulty reading on the direct connection from cdi, check the harness that might be any grounded wires. check also the setting on the koso ofcourse.

Haven't got any pics of your wiring or a diagram have you?
