I have a 93 legacy ss that I'm putting a ej20 in and I want to make a new engine harness for it but I can't find the terminals anywhere can some one help on where to buy them at thanks

You mean the pins that fit inside the plugs that go into the ECU? I don't know where you can buy the exact same terminals, but I do believe that these will work:

For the big pins: http://www.mouser.com/Search/Refine.asp ... 1-175027-1
For the small pins: http://www.mouser.com/Search/Refine.asp ... 1-175061-1

The pins for at the three plugs at the enine and for the sensors them selves I am going to need to change about half the harness

Oh. I'm afraid I can't help with that side. Most people cannibalize and Frankenstein stock harnesses; I haven't heard of anyone making a new one from scratch.

If you use your stock intake manifold harness, you shouldn't need to modify it that much... The only big difference is the four ignition channels rather than the stock two. Right?

Well the engine already has a diamond coil pack on it I know I need to change the TPS wires and IAC and possibly injectors my problem is the round connection on the engine I got comes out on the passenger side where as the legacy is all on the drivers side also I'm not really shur what the engine I got is out of it has vf24 Turbo yellow injectors and the tranny is out of a jdm spec b legacy but I'm not shur if that is what the engine is from Because if I knew that I could use the harness on that engine repin it if needed and I'm pretty shur the round plug is all grounds and ground them to the intake

Your posts would be a lot more clear if you used some punctuation.

I can't tell if you're asking a question.

The engine already has a diamond coil on it stock? So that shouldn't be an issue. I know I need to extend the IAC and TPS wires and possibly the injectors. My problem is the round connection comes out on the passenger side and I need it on the drivers side for my legacy. I am almost positive all the wires on that connection are grounds? If so can I connect them all to the intake? My other problem is thatim not shur what the engine is exactly. It has a vf24 yellow injectors and is a 2.0. STI? What throws me off is the. Tranny I got with it is a 4.444 5 speed out of a legacy spec b 96,97,98 ish don't remember exactly now. But if I knew the engine wouldn't it make it easier using what's on it? Rather than messing with the 2.2t harness. I know I would have to run a wire then for the TPS. Am I missing anything. Sorry about punctuation before.

Diamond or not diamond is not an issue. But it sounds like you're saying your EJ20 has a coil pack as opposed to one coil on each spark plug -- is that right? If that's the case, then, yes, ignition won't be an issue.

When you talk about the "round connection" do you mean the round 8-pin connector on the intake manifold harness? On a stock Sport Sedan, yes, those are grounds. If you want to see if that's the case on the EJ20, trace the wires and see where they go.

I would say it's easier to use one car's wiring or the other's. Mixing two completely different cars' wiring doesn't sound easy to me. But you're talking as if you know that the pinouts on the other two connectors are the same on your EJ20 as on the EJ22T. How do you know that?

That's what I don't know but all the plugs are the same I just wish I knew what the engine was so I could get the pinouts . I would use the 22t engine harness but I have plans for it and don't want to seperate it. Maybe I should start a thread in engines and see if someone can help me I'd the engine. That's y I wanted to make a harness so I could just copy the 22 harness to fit a 20. Thanks for the help.

I'm confused. Are you hoping to modify the EJ20 harness or are you hoping to make a new harness?

If you're using the EJ20 harness, why would you need to extend the TPS and IAC valve wires?

In any case, if you want to check the pinouts, you can just grab a continuity tester and the SS wiring diagrams and figure it out.

I'm confused as well.

I really want to make a new engine harness but if I have to ill reuse the one on the 2.0 and just modify as needed. I would rather a make a new one which is y I need the terminals I have the plugs I just need the pins for in them.

If you don't want to sacrifice the EJ22T intake manifold harness you have, I would just try to get another. If you're expecting to modify it anyway, you could just get a non-turbo harness and modify that one.

If you really do want to buy all the connector housings and pins, I would start paging through Tyco/AMP's catalog; I believe most of the connectors on the car are made by AMP (which is now owned by Tyco).

Awesome I live ten mins from tycoon and know some one who is a higher up maybe I can show him and maybe even get it thru them I didn't even think of that thanks alot

vrg3 is the man with the answers lol

HI,

Did it come w/the ECU? This LINK shows possible options.

It sounds like yours is either an EJ20K or EJ20R:

LINK for Subaru engines w/pics, and the Wikipedia EJ LINK.

Read THIS POST about the VF24.

Post a pic of the intake manifold and throttle body. You might be able to use your TB off the SS or another NA Legacy and throttle/cruise cables will work like stock.....If so you only have to deal w/the IAC...or @ least fewer items....but I'm guessing yours has the 'divorced IAC' that won't work w/the LHD TB.

If interested and want to run the EJ20's 480cc yellows side-feeds look up EJ20G Rob tune. Rob may be able setup an EJ20G ECU to take advantage of the 480's/VF24.

But you probably know the stock EJ22T pink injectors will fit your EJ20X's fuel rails if you're staying w/the stock ECU.

Yea that's my next issue is finding a ej20g ecu that is compatible with his tune but I need to finish up some small stuff and get it in and then that ecu should be the last PC of the puzzle
