Then you can either read the manual that came with it, or/and tell us which one it is, and it's possible we migth be able to help... But with the current amount of info my best advice is.... Eh.... Good luck!....

Um... green wire to coil as in the signal for the coil then... Not really the tacho signal then... So if you have it wired at the plug up front, it probably won't work...

Not sure where you did wire it though, so I'm guessing...

i pulled the guage cluster and wired the new tach off the leads that went to the old one as they were labeled off the back of the cluster assming the yell/grn wire which was the only unlabeld one was the said signal from the coil.... was that assumption wrong? if so where would i find the appropriate wire?

That wire is indeed the tacho signal wire for the stock cluster... But that's not the same as coils unfortunately... The tacho signal is 5V, the coil signal is not 5V... Hence no movement...

The coil signal is down the frame towards the coils, yellow/blue for one and blue/yellow for the other... Have a look here... It should help some...

Because it runs on computer voltage, 5vdc. The coils are 12vdc.

The wire you are using now goes 0-5-0-5-0-5... The other goes 12-0-12-0-12-0-12... The tacho is nearsighted and doesn't see stuff smaller than 11...

Doeas that help yer thinking parts...

Yes, the two wires between coils and ignition unit... just pick one of them...

Also remember that it's a wasted spark ignition, so that might have an effect on your tach readings...

alright im connecting to the yellow/blue wire that runs from the coil to the converter unit from #2 why is it still not working? i tried it before and after the connection to the rest of the harness... still nothing? is it possible that this tach doesnt work with our bike? im really starting to get worried.. i am way past the point of no return to go back to stock....

Well at least my tach works...... I'm not even going to bother with a come back to your insults. Have fun with the POS you bought as I have much better things to do than to try and help such a fine member as you.

Carry on.

Well at least you have come to your senses..... We all have had frustrating moments and I was wondering how just correcting so misinformation that you had post deserved being cussed out.

Good luck with your project.
