hello i am mario i come from italy i have some problem with the original cable of my z550 and i want put a motogadget m unit i have understant how it work the only think is the ignitor connection maybe someone can explain me the wire color i have to connect from the m unit aux to the ignitor box and ignitor coil

I don't have the answer for you, but just wanted to say... Your bike looks amazing! I love it.

I am not sure if I understand your question quite right, but the M-Unit is supplying B+ to the ignition coils. The coils are fired by controlling the ground side of the primary winding by the factory ignition box. I would have to look up the specific schematic for your bike, but if you trace out the red wires off of each ignition coil, they will tie together and terminate at the M-Unit supply point.

thank you carwash is a kawasaki kz550b i have change the tank is the same of your motorcycle and ......
i have to put a relay becouse i have buy this motorcycles the engine is good 20000 km but the electrical is really bad i have 2 relay one home made fuse box in the diagram i have to connect the fuse box and in the manual says ..........
i have to put some other thing relay or something like that ?

M-Unit’s Starter Motor Output „start“
Starter motors which coming with solenoid and a solenoid current consumption of maximum 30A
(like Valeo, Bosch, Harley Davidson) can be connected directly to the m-Unit’s „start“ output. In this
case a cable diameter of 2,5mm² has to be applied. All starter motors with external relay (like
Japanese Motorcycles) have to be still powered via the OEM relay. In this case m-Unit’s output
„start“ is connected with the relay which switches the actual cranking current (>100A). Some
Motorcycles have an additional relay to switch the start relay; this second relay is not needed

thank you for your answer the red wire for the ignition coil and i have to connect also to the ignitor box what cable i have to connect :dry:
