I was looking at installing my Apexi Muktichecker and have had a disagreement with it already regarding the pin outs.

 

Baiscally the guide is saying the power is supplies by Pin 59 on the ECU, but testing 59 has no power. Pin 58 has a constant 12v. Should Pin 59 be a power source?

 

With the unit connected to pin 58 it has a constant power, is this right, does it not switch on with ignition like most things?

it should be fed from ignition power, but pin 59 has no power and 58 had constant, so i might just feed the power from the ignition instead.

Yeh. just feed it power from a direct ignition source instead. Do you have the ECU pin out wiring diagram.....Im not sure I have a complete list available but I have a list somewhere with the majorty of the important ones .... Speed, Rpm ..etc
