hey guys..

if u want the long story short scroll to the last night.. otherwise read on

i bought a JDM front clip.. pulled the motor rebuilt it with new everything..

and swapped it into my FD.. including the engine harness since it was in much better condition than mine.. (no KFC extra crispiness)


after bolting and tightening everything and so close to starting the car..

everything was going well.. minus a couple wires I had to extend.. everything plugged right in to the US spec..

until I've discovered something..

the end of the harness that passes through the firewall..

theres a couple yellow clips that go into the ECU they're the same

the white clip higher up the harness is the same


BUT...


the Blue connector is not the Same..

a) what does this connector do?

b) the JDM has 3 pins on one side 2 on the other.. the USDM one has 2 and 2

c) should I lop of the USDM connector my old harness. and use it on the JDM one?

or should I lop the JDM chassis conenctor off and put it on my US spec chassis?

or should i lop both connectors off.. and try to hard wire them.. hoping they have matching colors?



I need help please.. i really wanna get my car back on the road plz..

 

use the usdm harness thats what i did with mine and i bought a jdm engine and all worked well

 

I can't.. my US spec harness is exteremely hard and brittle..

the JDM one is soft and pliable and in great on condition..

it's only one connector for pete sake...

there must be a solution!

 

Please help!

can someone at least tell me what the Blue connector is for?!

 

Blue clip? anyone?

am i just supposed to start the car without it or wha?

 

post a picture of the connector.

 

it's the only one..

after the Big rubber plug that goes against the chassis..

there's a couple yellow connectors that go to the ecu

there's a white connector that goes up under the dash somewhere

and then there's this blue connector..

 

Don't know if this helps, jap harness at ECU end.... haven't noticed a 5 pin plug -



in the car

 

Yes billy that's the one! the blue one..

it's not 5 pins in total.. just on the 2 "sides" of the plug basically.. there's 2 rows on the left and 2 rows on the right

on the JDM one there's 2 rows on one side.. 3 rows on the other side..

 

tommorrow, i'll be trying to fire up the car...

please guys...
