SoobieDoo Posted August 29, 2010 Share Posted August 29, 2010 I've got a build that's not really been started, but now have a '96 legacy EJ for it: http://www.ultimatesubaru.org/forum/showthread.php?t=111205&highlight=snow+wagon The first thing that I could really use some help with is the OBDII harness. I've searched and found some of the differences, like the fuel temp/pressure sensor, but haven't seen what's needed or how they're dealt with. So just what I'm I getting myself into here? Thanks in advance, ~Eric Quote Link to comment Share on other sites More sharing options...
Gloyale Posted August 30, 2010 Share Posted August 30, 2010 The OBD II swap I did was the easiest. Fuel temp sensor won't keep it from running. You can trick that with a 1k ohm resistor. just don't cut out the OBD II connector like i did..lol Quote Link to comment Share on other sites More sharing options...
SoobieDoo Posted August 30, 2010 Author Share Posted August 30, 2010 Nice, I'll try that resistor trick! Do you have a thread on that build, or is there anything else different? The OBDI I've done wasn't that hard...just really time consuming. Think I'll keep the OBDII connector. Quote Link to comment Share on other sites More sharing options...
SoobieDoo Posted September 9, 2010 Author Share Posted September 9, 2010 Anyone have a ECU pin-out for a '96 legacy? The FSM I have apparently lacks that, and it was of great help in numbchuk's write-up! Quote Link to comment Share on other sites More sharing options...
dhise Posted September 9, 2010 Share Posted September 9, 2010 Anyone have a ECU pin-out for a '96 legacy? The FSM I have apparently lacks that, and it was of great help in numbchuk's write-up! I have a pdf for the '96 ecu pin out that I got from Numbchux a while back. PM me your email and I can send it to you. Quote Link to comment Share on other sites More sharing options...
SoobieDoo Posted September 11, 2010 Author Share Posted September 11, 2010 Thanks, dhise...exactly what I needed! So far, so good. I've not found anything other than the fuel wiring that's extra, but several bonuses. No bulky SMJ to cut out, separate engine harness plugs from the front garbage, improved ECU plug, and of course the OBDII plug. I'm liking this harness more than the old 'uns.

SoobieDoo Posted November 16, 2010 Author Share Posted November 16, 2010 Well, after a little break, the harness is almost done. Just need to solder up power and grounds, but I would like to know what's up with the pressure source switching solenoid!?! I know what it's for, but are you guys doing the ODBII swaps hooking it up??? The plugs in question are in the '96 FSM, section 6-3, pg. 118-119: No's B1 and B2. Again, any help is greatly appreciated!!! Quote Link to comment Share on other sites More sharing options...
Gloyale Posted November 17, 2010 Share Posted November 17, 2010 I installed the Solenoid and the "boost Sensor" (pressure sensor) on mine (96 Outback 2.2 harness) I ran it without them for a while, mostly because my donor car was wrecked and that solenoid and sensor where damaged. I had to get another set from the junkyard. FWIW, it ran fine without them.....but did throw a code for it. Same with the fuel temp sensor.

I'll be getting some lego parts anyway, so it may behoove me to get those parts for trips up Mt. Hood. Quote Link to comment Share on other sites More sharing options...
jrettenmayer Posted November 22, 2010 Share Posted November 22, 2010 What are the pressure sensor/solenoid for? Quote Link to comment Share on other sites More sharing options...
Gloyale Posted November 22, 2010 Share Posted November 22, 2010 Sensor compares Atmospheric pressure with intake pressure. Switching solenoid switches the port on the sensor between Intake vac and Atmosphere. It's basically a MAP added to the MAF system. Quote Link to comment Share on other sites More sharing options...
jrettenmayer Posted November 23, 2010 Share Posted November 23, 2010 Is that the same sensor that's bolted to the passenger side strut tower, or am I thinking something different? Quote Link to comment Share on other sites More sharing options...
SoobieDoo Posted November 23, 2010 Author Share Posted November 23, 2010 Is that the same sensor that's bolted to the passenger side strut tower, or am I thinking something different? I've heard that's where it's located, and I'll prob get it for the drastic elevation changes 'round here. P.S: Since this is my build thread, your feedback is required. Looks like I'll be changing on the tires. P/U some alloy 16's for it the other day, so even if I go with the retreads it's apparently a different style AT in that size. Might go with dedicated winter tires, then the retread MT's on steel wheels. Quote Link to comment Share on other sites More sharing options...

Yes, black box with 3 wires, on the same bracket with the solenoid with 2 wires. Connected to the engine with a small vac line with a weird little filter in it.
