2005 WRX ECU diagram pinout
I got HKS turbo timer and Autometer air-fuel ratio gauge. I need to find:
-RPM signal wire
-speed signal wire
-o2 sensor wire
05 ecu diagram is different than 02-04 and HKS manual covers only these years. Does anyone have ECU pinout for 05 WRX????????

The tap-in type A/F gauges are worthless, and you can only connect them to a narrowband sensor which in the turbo Subarus is the rear/post-cat 02. Best not to bother unless you really just want the blinky-lights.
Whatever you do, do NOT attempt to connect the gauge, or anything else, to the front 02. It has to be left alone.

we are trying to save you a loom and time and money
if you tap into the rear 02 sensor you wont get a correct AF read if you have any cats. so its just going to be flashing lights
if you got to the front it will draw on the volts and give an incorrect reading and make the car run like crap
we arent saying if we like it we are saying its useless
ill give you the info but dont post up that your car isnt working right because you know this going into it

ok, thanks, I guess I'm gonna sell that gauge.
My HKS turbo timer has other functions such as 1/4 mile run time, 0-60, 0-60ft time, peak speed, peak RPMs, that's why I was looking for a RPM and speed signals
