good luck trying to wire that up, some how or another its gotta get the RPM's from the ECU or engine sensor so there has to be wires for that. Also theres going to be a power wire most likely and always a ground

Find out who makes it and get a schematic. Or return it for one that does.

Sounds like he has the schematic of the tach... he's confirming the wires on the bike.
I can't tell if the "red and black" is 2 wires or a striped one, and can't tell if the "black& yellow" is 2 wires or a striped one.
Then he gets into listing "should be", but I don't know if he means connected to that color on the bike, or what.

What he needs is this, but for his bike...

Thank you that helps, by the way the tac is a THG ldtam13t for $34.99 all I know is what is in amazon add.

That's for a lightning (pretty sure)... MIGHT be similar... but you should be able to find one for a Blast.
