Re: Wiring issue
 

Test point 8, the voltage should drop considerable more.

Where did you spice in the the green wire of the grey harness?

K I think I have my problem figured out I was using the Wrx wiring diagram not the sti one so I will try hookoing it up that way tomorrow and see if that works better.

Re: Wiring issue
 

Great news, thanks for the update.

It did puzzled me for a while.

Re: Wiring issue
 

Hi there, I have similar problem, so I ran diagnostic on points you suggested, and while TP5 and 8 are getting ca12.3V with engine off/14.4 engine on, point 23 won't give more than 0.25V.. At this point I am sure some contact is wrong, just have no idea which, and cannot find pin description anywhere. Just to complete info, I am running first test described in the manual, w/out FAV, etc connected, and I am getting no reaction from system at all.

Re: Wiring issue
 

can you measure the voltage on the 5A fuse. Both side.

Re: Wiring issue
 

0.26V, both sides.

Re: Wiring issue
 

Check the red wire of the power connector (4-way molex type), there should be 12V there.

Re: Wiring issue
 

11.16V with engine off.
