Pooparu Posted July 8, 2007 Share Posted July 8, 2007 I've noticed that some ej22's come with 2 plugs (coming from the motor and connecting to the main wiring harness) and some come with 3 plugs. Why is that? I know it has nothing to do with the transmission (auto vs. manual), the only thing I can see at the junk yard is that the 2 legacy's that I found with the 2 plug system are 1992's. I reason I'm asking is that the ej22 that I put in my hatch was a 2 plug system and the wiring harness that was installed is a 3 plug system (swapped the intake manifold to make it a 3 plug system) but I can't get the motor to run and I'm wondering if the cam pick ups on the back of the gears are different on a 2 plug system vs. a 3 plug system. It seems more and more that I have a timing issue rather than a wiring issue so by swapping out the cams from a 3 plug system on to my motor might solve my problem, but I have no idea what the plug differences mean. thanks, earl Link to comment Share on other sites More sharing options...
nipper Posted July 8, 2007 Share Posted July 8, 2007 have you tested the sensors? There may have been a reason the car was scraped (like a bad sensor). nipper Link to comment Share on other sites More sharing options...
Pooparu Posted July 9, 2007 Author Share Posted July 9, 2007 have you tested the sensors? There may have been a reason the car was scraped (like a bad sensor). nipper no, but the motor ran when I pulled it. Link to comment Share on other sites More sharing options...
86BRATMAN Posted July 9, 2007 Share Posted July 9, 2007 The different plugs just seems to be a difference in year. There was a discussion on legacy central about this subject. Link to comment Share on other sites More sharing options...

I poked around a bit and didn't find the thread so I just posted the same question on that message board. Link to comment Share on other sites More sharing options...

Numbchux Posted July 9, 2007 Share Posted July 9, 2007 yep, and the important part from the post above: "the smallest plug (should be 2 pins tall by 4 long) are ALL grounds. this was part of the problem with my origional install. I saw these grounds, but could not find that connector (my donor legacy had only 2 plugs). I later got another copy of the wiring diagrams, that looked identical, except when referring to these plugs. this diagram only had the 2 plugs, and showed the same ground wire cluster to go through the larger of the 2 plugs. instead of a plug of their own."

It was herehttp://www.ultimatesubaru.org/forum/showthread.php?t=68357&highlight=wiring+obd%2A Hmmm, a lot of very interesting theories. I guess I'll switch all the timing gears over to the 3 plug system just in case then if that doesn't work I stair at the wiring some more. Link to comment Share on other sites More sharing options...
Legacy777 Posted July 10, 2007 Share Posted July 10, 2007 You don't need to do anything with the timing gears Link to comment Share on other sites More sharing options...
Pooparu Posted July 10, 2007 Author Share Posted July 10, 2007 You don't need to do anything with the timing gears I'm getting desperate and grabbing at straws here so I'm going to try everything I can to get this thing running. It might seem like a long shot but maybe in the process I'll find the real problem. Link to comment Share on other sites More sharing options...
Uberoo Posted July 11, 2007 Share Posted July 11, 2007 have you checked the timing on the motor?something might have shifted when you put it in. Link to comment Share on other sites More sharing options...
Pooparu Posted July 11, 2007 Author Share Posted July 11, 2007 ya, I triple checked it. I'm going to mess around with it this weekend and see what I come up with. have you checked the timing on the motor?something might have shifted when you put it in.
