Ive bought one all wired up, apart from one wire. I think i may of found rev signal from pin 6 on the black dial plug... only it only floats around 6v no matter what rpm. This is the only signal that moves with rpm and its not a lot. Yet using it to setup the shift light wont work.
I have tried to get a signal from the diagnostic port but think predator management does not work with this?
Any ideas what voltage im looking for and from what wire, i have searched here and google, i see other members have fitted aftermarket tacos but all have failed to state what voltage to look for.
Thanks in advance
