I am curious as to how everyone else has there airflow sensor hooked up, I have the wiring diagrams that numbchux set me up with from a 92' legacy but they are different from what the wiring diagram is for a 90' Legacy. Also, i am wondering how everyone has there ignitors set up, and what exactly does this thing do? The grounds for the ECU A10, A11, A21, A22, B1, D14, D15, and D24, D25. Do these need to be grounded to the motor or just grounded (like to the strut tower?) On the engine harness one of the gray plugs is all black grounds, where do they go? Do i need to hook them up to certain things? I am really regretting just tearing this harness apart and getting it so screwed up. And the only code my ecu flashes is a water temp signal wrong code. This car just cranks and cranks, doesn't even try to start, i have fuel, don't think i have spark? But most of all i have a headache haha:confused:

So got everything rewired after working in the garage till 9 last night and today ran all of my new wires to everything and even hooked up and mounted my new neutral switch (if it's even necessary) to where my clutch stopper should be. I have every thing but my C10 wire hooked up which i'm pretty sure is why it didn't fire up. I also have a question about the VSS on B58 Pin 11, do i need to hook this up? And if so where to? Also i am curious to know if and where i need to hook up the engine tach output on B56 Pin 16? Is this what is going to make my tach work in the car? Thanks for all your help guys!:cool:
Only thing i found on hooking up the VSS was for an 84 Subie, mine is an 85' GL and it doesnt have the 2 pin black connector on the back of the speedo, so i don't really know what to do.

EY thanks chux for the diagrams! Very cool. I hope this works, i brought home some shielded wiring left over from work so i might run some new ones for the cam/crank. We'll see if this is gonna work.
And the reason i changed it from the way i had it when it ran and was draped over the fender is because i am pulling my wires through the AC line holes in the firewall that are on the pass side and it made more sense for me to just run the wires straight to the sensors opposed to running them all the way over to the harness connectors. I'm gonna head back out to the hot garage and trouble shoot some more, hopefully i get this figured out. Oh and yes i have inline fuses, i hate to burn up the ecu haha. Thanks for the help guys...i can't believe i didn't sign up on this site 10 years earlier!

I am currently in the middle of my EJ22 swap from a 90' Legacy into an 85' GL Wagon and followed numbchux write up which was awesome i couldn't have done without it. I also hung the wiring harness over the fender of the car and door and started the engine and it ran. Okay, so since it ran i decided to fully install. I also decided to run all of my ecu wires through the grommet for the AC, because my car doesn't have it and mount the ecu under the glove box. Well long story short i got it all hooked back up and it will not start! Just cranks. The only thing that i have done different is i hooked up those signal wires (the gray ones with the shield) straight to the sensor instead of going through the engine harness. Does this matter? Does the ecu need to see those shields? Also can anyone point me in the direction of a wiring diagram of the engine harness, like which colors go to what? Thanks a s**tload to anyone who can help!:-\

I have power where i need it i think? I've checked and rechecked all of my wires. I annilated that harness!!! haha what the hell was i thinking? Oh well i've pretty much ran new wires to everything. I think i'm gonna run all of my grounds to ground again and not worry about the ones coming out from under the manifold and make sure everything is good, if it is then i am gonna run down to this subaru parts place and pick up another ECU, the guy said he had like 10 of em and sell me one for $50. I remember i accidentaly dropped mine onto the concrete floor when i had it out so maybe, just maybe i broke it? Everything else is hooked up right and my fuel pump even comes on. I was getting really upset but things go even worse when you get super stressed out. Thanks for you help Gloyale you're a true patriot, and when i get this thing running/driving i am gonna post all of my pics!
