So i am about to get a jdm swap pre soon AND I like to know when u use jdm swap so can i use the harness on the jdm one.? ecu's are in different location so will that be a problem

 

you can use either harness. JDM, turbo, NA.

just maker sure its the same series. it makes it easier.

 

if you use the jdm harness you will need to extend wires

 

JDM harness is shorter than the U.S. harness due to the position of the ECU. You CAN use the JDM harness but many people (myself included) would say that it'd be easier to modify the U.S. N/A harness assuming you're doing a N/A to TII swap.

 

Dont waste your time with the JDM harness. Theres plenty of people on the forum and online who will sell the one that fits for a reasonable price

 

Click link in my sig.

 

I cant tell you how many times ive seen rotary rocket comment on this... listen to him lol

 

That's why I added the link to my sig. I keep repeating myself.

 

Thanks 4 the help on mine btw, got my swap running verrrry nicely

 

No problem. It's actually a very simple process when you go into it fully prepared.

 

always little things that get left out though...I turned in my idiot cluster cover to get fabricated to a gauge pod 2 months ago and the guy still hasnt finished!

 

no i have a s5 t2 but who ever had it before cut the whole harness a part so i wanna use a fresh one so i dont have the problems that i am having now

 

just a suggestion be very careful when buying jdm motors they're stored improperly and were brought on a ship that was around open salt water for about a month and 9 times out of 10 they will need a rebuild.

 

JDM fail! I hope you get to see the motor and compression test it before buying it.

 

there is a jdm place about 10 minutes from where i am so i am picking it up so i ll see the comdition and test the compression my self

 

is anybody know if a na, auto front wiring harness is same as t2 manual same series harness or not?????

 

Not sure but i would think they aren't the same. Dont quote me on that tho.

As for this place being 10min away from you......that is friggen awesome. Hell man im not to far from there, how much does a T2 short block cost from them if i pick it up?

 

You can consider all NA engine management harnesses of the same series to essentially be the same, whether they are for autos or manuals. That being said, NA EM harnesses are not at all the same as TII EM harnesses. You shouldn't consider adapting an NA harness for a TII; it's just not worth the trouble, and you will lose a couple things (ASV, knock box).

 

contact Japan2LA if you want JDM engines...

 

not sure but they usually sell the whole swap with everything around 1200-1500 with trans and harness

 

Do they have FC front clips there?

 

yea they have clips everything if they dont have it i no other 2 have it

they all in north jersey and not that far from each other

 

i have a qeustion about using a usdm s4 turbo2 engine harness on the s4 n/a being same years like 87 would it be same plugs? would it be a plug and play or i have to modified some thing i looked around no one gives a straight answer.

 

Look at the jpg attached. See the wire colors in ( )???? Those wires are all peculiar to the turbo car. If mated with a non turbo FRONT harness they will not perform their purpose.

The harness on the engine is the EM harness. See your local free online wiring diagrams for what each wire does in life.

Plus the two alternator wires are not in the Turbo EM harness. They are in the Engine harenss on a Turbo car.

Figuring out what each wire does in the harness is simple. Not all the wiring diagrams are involved. Throw all the wiring diagrams that have anything to do with the Radio, ABS, headlights,sunroof, windows, heat and air etc to the side and just deal with items that effect the engine, alt, wipers, instruments and that takes care of 90% of the wires.

 

so which wires should changed?
