mk wait... http://i1099.photobucket.com/albums/g381/ts39136/subaru%20wiring%20tutorial/PowerSupply.jpg in this diagrahm it say that wire is conected to the yellow alt wire which does go all the way back to the fuel pump relay.... is this right??

2 ignition relay ECU wires?????.....

okay ive stripped down the harness a lot and now im to the point where im fallowing the diagram in the ej wright up, with the ECU fuel pump relay, ignition relay, and such. quistuon is on ECU pin B12 theres the ignition relay wire, its not conected to anything... because i cut it to wire up as the diagrams says. dosnt even show it on the diagram! where does this wire go hooked up to? the fuel pump wire like it was? ignition switch? am i tapping thouse two wires that go to it, into the EA's ignition switch?

oksy do ive stripped a ton out so far and ive gotten to #1 theres two black boxes lables as fr-3315 and the other says illumi con unit. are these stripped out too?? i put up a picture but idk if itll work... #1 next is a white connector that i think leads to the rear harness? it plugs in to the right side of the car, near the floor/door along with a blue and black connector, strip out these? okay and the cruise control, i read somewhere where the ecu still needs some signal form it. so what needs to be done there? what wires need to be looped so the ecu still get a signal?

http://www.numbchuxconversions.com/Files/Harness%20info.pdf this is a good file to have on hand! thanks nux!

http://www.powerlabs.org/jdmsubaru.htm this link helped! Not going into the same car but still, with the stripping. -so any wires that don't lead back to the ECU can be cut out. Is pretty much what the link said. Sounds fair enough.

HARNESS STRIPPING. -okay, I separated the harness into two parts at the smj so I don't fe over welled and lose my place, #1 harness, the part that came out of the drivers side fender by the batter. #2 harness, ecu and the rest of the bunch. I've stripped out of the #1 harness, headlights, ej fan, and a abs blug. Now I started on the main fuse panel that's under the hood, I've taken all the a/c relays an wires out of the harness. But now am a little confused. There's four clips left. What else gets striped out of the fuse box? It's hard to adentafie which wires go to what fuse. So any sugestion? image1.jpg

harness completely removed and labeled!

well more progress! i have about half the intiror harness labeled, and almost all the engine bay harness lables and gettting ready to push in through the fire wall! i gotta say now that im actually pulling the harness its seeming easyer and easyer to actually strip it down to the main components. its pretty strait forward. -Prwa

Okay made some major progress today on getting the harness out! But have a couple quistions. -in the picture I put up with the red line to the right of the T of the harness I've gotten to that point. On the right of the T looks to be just cruise control, heater and relays, and also stuff that lead to the back of the car. -can the harness be choped right there, to the right side of the T, like it shows in the picture (red line)? -by the ecu there's a goldish looking box that looks like another ecu, says HS atomatic electronic contorl. For the tranny? Cut it out? taking Fender off tomarro. To get the harness through the fire wall.(if I don't work) Haha.

dang... you got it pretty lucky... you still have some key left... my is all wore off.. and now am dealing with the same problem...

non taken! haha. and yeah that makes a lot of sense! ill be taking the smj out like you said! and solder it up. im not to bad at it. -questions are the key to success, and so far im feeling much better about the harness stripping now that ive asked probably a million questions.. haha... seeing it in the picture on nux's web site through me off... i came across a file from him that tells exactly what needs to be taped into in the old ea harness after the strip and installation is started. anyone know where that is??

ahhhhh, yeah im going to try and label everything as best as i can so i don't get something mixed up and **** my harness... mk this is all making way more sense!! ahhh so everything that is left on the smj after the strip, will be cut and re-soldered to its same pin, to eliminate the smj? makes more sense! but it really doesn't really have to be done? so i could just leave it after striping down the harness? haha

yeah your right! that grey box is the smj. my mistake... mk so i do have the right concept down. -the ecu sends out a signal (or what ever that is sending) that has to come back to it, so thats why they have to be soldered there, so pretty much its making a loop. is there a list of all the pins that have to be looped (soldered) somewhere?

http://www.ultimatesubaru.org/forum/attachment.php?attachmentid=8917&stc=1&d=1315789727 "Move to front passenger seat. Jeesh... This is turning into a book. From the front passenger seat, find the wiring harness that comes through the center of the firewall near the center of the windshield. If you don't see where it goes through the firewall, keep removing heater components until you do, picture above. Once you find this bundle of wires, find where it Y's and goes left or right. Cut everything that goes to the right (passenger side, red line in picture above), there will be 50 or more wires here. Pull the remaining harness from the engine bay into the passenger compartment. " is this the spot in the picture where your talking about (SMJ)? where it makes a Y? the website says the red line is where you cut the harness to get rid of stuff. and the ones that need to be soldered are the ones that come from the engine bay that go to the right (in the picture) (orange lines) that are suppose to go back to the ecu and need to be soldered? i think im starting to understand this stuff i hope haha.

i just read in nux's write up about "a unplugged wire is the same as a cut wire?" so anything that is unplugged (other than the green one for running codes) under the dash needs to be striped out of the loom? clear to the ecu? thanks!

AWSOME!! im going to start taking the dash apart tomorrow and labeling things! im going to assume that you label the plugs with there numbers in the manual and maybe the name of the plug? i gotta say everyone who ive ever in countered on here has be really nice and very helpfull! thanks!

Thats fine, im starting back up school at PSU real soon and so im going to be really busy.. although having a class that taught this would be awesome! not sure if id be able to afford it but still way cool! well if i come into some money to pay for my harness to be stripped ill let you know! but if i get it out and feel comfortable stripping it out then ill finish it my self and save some $$ ) okay then, a specific question that i hope isnt to broad.. you said that there are about 27 different wires in the loom that have to be soldered, are these wires being soldered to something else in the loom? could you tell me what these wires are? and what there being soldered to? prolly a lot of not its fine ) what all should be left on the harness (after) striping in for my 90 loyale? i have the wiring diagrams for a 92 legacy but cant find the 93? are they the same? i just found this link, not for a loyale for a bug. but would it still be the same principles? http://www.shoptalkforums.com/viewtopic.php?f=28&t=136053 thanks! GD

very interesting.... and sounds very complex, ill start taking it out of the car and them ill decide if i want to do the whole thing haha. mk so if i were to send it out to someone, would i still want to label everything as im taking it out so it would be easyer for the harness stripper to work on it? how much do you charge? - its a 93 legacy ej22 going into a 90 loyale 5speed 4x4. could we work out a deal maybe? im more than willing to learn how to do this, and i learn fast!

Okay ive read the write up for the ea-ej swap sevrel timesand am feeling pretty good about it. and I finnly got my doner car, 93 legacey! But the one thing I'm feeling a little fuzzy on is the harness striping. I know there are guys on here that'll do if for about 200$ but.... I'm a poor guy, and will do just about anything to avoid spending money, (hence is why I fixed my girfreinds parents car in trade for the legacy I have now) so does anyone have a detailed guid of what all need to be striped out of the harness and what needs to be dubed in and where (for oil presure and such) from what ive read I should strip out everything that dosnt obtain to the motor and conected to the motor? Is this right? I have the fans for the legacy too, so I would leave that in the loom? Fuel pump relay, there's one already in my loyale along with the fuel pump, do I still need to wire in the legacy relay and pretty much swap out for it, and forget about the other one? Same goes for ingnition switch? Can the rad out of the legacy fit in the loyale? Or can it bult up like the legacy one does? if there's anything else I should know, just say! Anything would help a lot! Thanks! -PRWA

This makes sence! So the strut blocks will be cut an an angle, so it there's no camber change?

That's the one thin I forgot on my post. Wouldn't it just be 4" blocks under over the strut? So 6 total for the front struts.

I'm getting ready to do a lift in my 90 wagon ea82, soon to be ej22. I've seen people make them using Just 2x4x.25x1" blocks, and putting them anywhere where they are needed. Such as 4 to drop the subframe with the motor, couple to space the tranny and rearend, and suspension. And then the stearing exstention. I've looked at sjr's lifts and it seems like that's all you really need they just make them look a little fanceyer and put there name on it. I do give it to them though they make some sweet stuff!! In a 90 loyale, is it just spacing everything the 4" I want? Nothing fancey has to be fabed? Stearing exstention, it's just 4"? Thanks! -PRWA

well i started looking at the timing belt agin and noticed the cam pulley on the drivers side was about 1/4" from the cam senson! so i compared to to the lego and it was way off!! long story short.... left it right and right is left....... i got the pulleys backwords..... thanks guys for the help!

haha if nothin else works, bang on it! work all the time.... the weird thing though is im getting power to the ignitor, i checked yusterday with my test light. but then nothing to the plugs... i know the ignitor is good because i swaped it with one out of my Legacy, ill try shaking wires today haha maybe ill get lucky. the crappy thing is it ran perfect befor i took it apart, (other than the oil leaking)
