JDM wiring harness on a spec
 

anyone used a jdm 13b rew manual engine harness on a A-Spec version before?

i did before and its alot of work. first you need to modify the (blue connector on the jspec engine harness) x-05 connector to fit on the dash connector, re-pin blk/yel wire x-05 jspec harness to blk/org dash, this is the power source for the injectors, then also if you dont want the fuel thermo check light on, you have to re-pin the brwn/yel wire from the jspec x-05 connector and pin it to x-14 connector blue wire.

is this just an estimate of what i have to do or is there more to do?

its the main thing you have to do, but let me verify all the other wires on the jpecs x-05 connector, so you can wire it up properly on the dash.

If you can please explain more about what exactly needs to be done.Im pretty close to the end of the swap and I was under the assumption it was only the 12 wire blue connector that needs work.

NOTE: PLEASE REMOVED ALL PINS BEFORE STARTING THIS MODIFICATION. NEXT, YOU NEED TO MODIFY THE JDM X-05 12 PIN (BLUE) CONNECTOR AND MAKE IT TO A 10 PIN CONNECTOR. I USED A DREMEL TO CUT MY OFF. CUT THE B/L AND BR PIN CONNECTOR OFF.

i hope this explains it. LMK if you have any questions.

So after this modification that you talked about, the JDM harness would plug right up in place like a USDM harness?

any pics. that would help :)

Ya, after modifying the plug and repining everything, it should plug right in like the usdm x-05 connector. I'll post a pic when I get a chance.

Ask the MODS to Sticky this thread...

I'll post up a picture of my setup too for the record. Very simple to do. Solder it for a good connection.

thanks for your help guys! much appreciated

aight this is the way i did my mod on the jdm x-05. sorry for the big pictures and pictures being blurry. i took it with my iphone holding a flash light so you can see it better.

did you guys try it yet?

Can some please post up what each of US 10 pin NON EMISSION connector wires stand for. I need to know so i can match them up.

Ive been searching for hours through the forum and fsm with no definition to the colors

do you have the jdm male connector? I had one when i bought my clip, all I did was cut off the male connector and solder it according to the same color off the USDM one. After that it just plugs right in.

problem is EM cars have matching colors to the jdm harness but non EM cars only have 3 matching colors.

Bump
USDM (F) front harness to JDM (EM) engine harness
Ive got a few wires down from the wiring diagrams but not sure/dont know a few.

did you follow the step above, im running the same set up your doing ( usdm front and jdm em harness. you dont match the wires, just follow the step i did and you should be good. trust me, ive check where all the wires go one by one and prolly more than 30x.


for example usdm front to jdm EM
G - BL
BL/G - BR/B
V/W - Y
Y - B/G

just let me know if you have any other question. sorry for the late respond.

Sorry
 

I apologize for resurrecting a dead thread. So im lame terms, should I be cutting off the JDM x-05 connector from the main engine harness and splicing in the USDM x-05 connector, splicing COLOR to COLOR, EXCEPT for the one brown/yellow wire? Or is there a certain wire from the JDM harness that needs to go to the USDM x-14 white connector with a blue wire?

Also, what exactly is this white connector here, and where does it need to be connected?

I also notice that the x-05 connector does not need this extension piece to fit into that other part. Is it necessary to be hooked up? it looks like in the picture above they have it hooked up directly. I apologize again for being so electrical illiterate. Someone to coach me through this part would be greatly appreciated. I am thinking this is the reason I have no power to my injectors.

If it fits in there then why would you want to swap it? I think they made the change to the bigger connector on cars 96 and up. None of the wires from the blue connector go into a different connectors.

I would just make sure that the color of the wires match on each side, also I would avoid splicing wires there especially on a connector that can be de-pinned so easily...

The white connector plugs into another female down there near the firewall you just have to look for it.

If that's the case then what were those previous guys talking about with connector x-14? Also does anybody know what that white connector is? I do realize it has to connect somewhere...

Please anybody, help!
