Pooparu Posted March 20, 2008 Share Posted March 20, 2008 I pulled this and several other wires from my 1982 Subaru GL Hatch with feedback carb and now my ignition isn't working. I did an ej22 swap so I was trying to clean up some wires. Would this have anything to do with it? Quote Link to comment Share on other sites More sharing options...
Turbone Posted March 20, 2008 Share Posted March 20, 2008 Where was it located? I want to say its the ECU, but I dont think so. If it came out of the drivers side fender it would be a anti-knock unit, but those were on the EA81T's. Quote Link to comment Share on other sites More sharing options...

Turbone Posted March 20, 2008 Share Posted March 20, 2008 It could be the fuel pump control unit. But without a parts book for the EA81's I dont know for sure. Quote Link to comment Share on other sites More sharing options...
ferox Posted March 20, 2008 Share Posted March 20, 2008 If I am not missing something my Haynes wiring diagram shows two things it could be: The obvious one is fuel pump control unit that Turbone suggested. Diagram shows a box with 6 wires. The inobvious is labeled as a seat belt timer. Diagram shows a box with 7 wires. With seven wires it must do something in addition to timing seat belts. It's near the glove box area. It doesn't seem likely though. I think I count 9 wires in your picture, so the diagram doesn't match perfectly in either case. The wire color coding looks a lot like some of the wires I spliced when I removed my external voltage regulator ('81 hatch), which I know your '82 doesn't have, but I would put my money on the fuel pump control unit. It ain't much, but it's all I got. Quote Link to comment Share on other sites More sharing options...
TomRhere Posted March 20, 2008 Share Posted March 20, 2008 The FPCU is mounted on the DS kickpanel behind the fuse block, and is about the size of a deck of cards. So that's not it. Don't recall seeing anything like that item when I gutted my '82 BRATs interior. I'd have to go out and look at things to be sure though. The BRAT is a California model, had feed-back carb with the ECU under the steering column. Quote Link to comment Share on other sites More sharing options...
Pooparu Posted March 20, 2008 Author Share Posted March 20, 2008 Wow, I thought someone would know this one right away. It is a strange box, and it wasn't mounted very well ether. As soon as I unscrewed the center screw from the little tray that sits under the glove box the thing just dropped out onto the floorboard. It was only held on by a single screw going through a thick zip tie. It was hooked up to the motor and I think the coin as well, but when I did my ej swap I got rid of all of that so the wires weren't connected to anything and they didn't run back to the main harness or fuse box so I just simply pulled it out. I'm afraid that it might be the ignition control unit, but I don't know where that is. According to my wiring diagram it has the same amount and same color wires as the diagram, but I can't imagine that Subaru would mount something this important so carelessly. I'm really racking my brain here to get this thing running again. It's killing me:mad: Quote Link to comment Share on other sites More sharing options...

Nug Posted March 21, 2008 Share Posted March 21, 2008 Yeah, you know, when things are already working properly, harvesting a bunch of wire probably isn't in your best interest. Just sayin'. Quote Link to comment Share on other sites More sharing options...
heartless Posted March 21, 2008 Share Posted March 21, 2008 It was only held on by a single screw going through a thick zip tie.....I'm afraid that it might be the ignition control unit.....According to my wiring diagram it has the same amount and same color wires as the diagram, but I can't imagine that Subaru would mount something this important so carelessly if it was mounted using a screw thru a zip tie, my guess would be that somewhere along the line it was relocated by some PO. Subaru would not mount something in that fashion. if you cant find the ign. control unit anywhere else, and you say the wiring count/colors match the diagram, then I would suspect that this box IS your ign. control unit....

What is the "coin??" it was hooked to? Not sure,but,I think it might be the timer for the belt/door chime. However,as mentioned,the wire count/plug shape seems incorrect. Does the chime still work?

Pooparu Posted March 21, 2008 Author Share Posted March 21, 2008 oops, I mean the carb. not coin. Yes the door chime still works. I'll put some more photos up tonight.
