Scooner Posted July 18, 2010 Share Posted July 18, 2010 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!:-\ Link to comment Share on other sites More sharing options...
Numbchux Posted July 19, 2010 Share Posted July 19, 2010 No, the crank and cam sensors do not NEED to be shielded. I had a problem with the wiring for the crank sensor on my wagon, and just ran 3 separate wires and it worked fine. it's been like that for probably 20k miles. I would consider that a last resort though. the shielding is a good idea to ensure that you have an accurate reading on those sensors. '92 legacy engine wiring diagram can be found on my site: http://numbchuxconversions.com/downloads.htm you might find the plugs between bulkhead and engine harness to be different, but everything else will be the same.

ShawnW Posted July 19, 2010 Share Posted July 19, 2010 So not trying to be a jerk but why did you change it at all if it ran before? That or maybe you popped a fuse for the battery hot/ign on wires to the ECM. Be sure you have a fuse on these if you don't already. Link to comment Share on other sites More sharing options...
Scooner Posted July 19, 2010 Author Share Posted July 19, 2010 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! Link to comment Share on other sites More sharing options...
Scooner Posted July 21, 2010 Author Share Posted July 21, 2010 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.

I would suggest running the wiring through the big rubber oval in back corner of the engine bay, rather thant hte AC holes. as for the VSS, there is a two pole connector, with a yellow/red, and a black wire, way up under the drivers side of the dash, near where the vacuum line and wiper wiring runs into the enigne bay. it's up there, I;ve located it for dealer cruise installation. Tach output get run over to the tach original tach wire, which would be the yellow one that goes to the negative side of the coil. Link to comment Share on other sites More sharing options...
