Hey all.
I have rejected Motogadget;s Pro instrument mostly due to its design and ordered KOSO TNT-04 instrument combined with BEP 3.
Maru Labs provides nothing for the specific instrument and Koso has a decent documentation but i m a bit confused besides the lots of reading and researching so i kindly ask for any help available.
1. Neutral light.
I have already purchased 2 Gpi sensors so lets assume that i have a working GPI.
Through Maru Labs documentation i have pin outputs for all 5 gears + a neutral output.
The critical question.
As per instructions I should connect the neutral to my KOSO instrument input ( white wire ) Does the Koso instrument lites the N indicator by receiving 12v ( as the input that lites the N green bulb in the original instrument cluster? In the KOSO instructions next to the Neutral description it displays a minus (-) signal . I cannot get it clearly.
2. Fuel lights ( 7L - 4L )
Koso has a configurable resistance setting so you can adjust according to your sensor. My K has the early thermistor type stick sender. Does anybody knows the Resistance Values ? ( Ohm ) ?
Thanks in advance
Below is the Koso main wiring path.
