i've seen a bunch of people use it but how do i actually wire it up to the ems? I'm thinking I'd just have to find what wire is the o2 sensor on my honda harness, cut it and and pretty much splice it into there, but on the techedge cable which one is the signal wire that i'd splice onto the plug with? Also is there anything else I'd have to wire up other than the ground, power, and signal to the EMS?


I'm figuring the signal wire would be the one that changes voltage (between 0-5 volts) so can i just use a volt meter? Or does anyone know exactly what colored wire it is from the tech edge cable?

 

I dont remember what color the wire was, but if you get a meter you can measure the voltage.
