Hello!

i have two questions!

#1 what pinout gives 12v signal to the starter? i have pin 43 hooked up to my start button.
just want to check for continuity on the signal wire.

#2 the ecu (power fc djetro) wont shut down when i kill the ignition switch. only when i kill the main power switch.
i have checked on the internet and i think i have wired it correctly..
this is how its wired.

constant 12v to pin 58
ign.switch 12v to thick black /red and thick red from the F3 plug.
grounded through enigne.
i have 12v to pin 49, 59 and 109 when the ecu is on and the relays are grounded through ECU pin 16.

i have traced the problem to the thick red wire that goes from the F3 plug to IGN/coil relay
when i turn on the main power switch the ecu fires up half way and apexi logo appears on the commander but nothing more happens.
then i flip the IGN-switch and the system is up and running.
and when i kill ign switch nothing happends. still running.
so i just want this to work as it should so i dont f*** the ECU memory.

if i disconnect red wire it works as it should. but kinda need the IGN/coil relay to be running so i can start the engine :)
