Ok, well im trying to swap a S5 JDM engine and Harness into a S5 USDM NA Chassis.

I know what your going to say, "use the NA Harness" but the car came without the NA harness =[

here are a couple of pics of things i have no idea what they are.

Also Where does the Engine Harness run in at, the Passenger or Driver Side of the Vehicle (USDM)

This connector is on the JDM harness coming off of the engine, its connected to all of the sensors on the engine. From what I can tell there is not female side of this plug ANYWHERE on the inside of the car. If anyone knows where this plugs into, or what I would have to splice please let me know.



Next, While in search of the other end for that plug above to connect to I found these plugs on the passenger side of the car (USDM) behind the blower motor housing. its the same setup at the connect on the JDM harness but doesnt have NEARLY the same wires or even the same amount, they were just empty connectors.




If anyone could show me a DIY or How to for the JDM harness that would be awesome.

 

There's a hole in the passenger's side behind the cruise control and charcoal canister. This is where the wiring harness passes through. The connectors you posted pictures of... more than likely connect together, just by looking at them

 

well they do connect to each other, but there arent enough wires to run all of the components on the engine

I DID figure out that those two connectors are what need to be connected, but I need to repin the connector IN the car to accept the JDM Plug, does anyone know where I can get the JDM pin out sheet for that connector?

 

these two connectors are for the wiper wireing. well some of them anyways.

 

yes I know that, I need the JDM wiring Diagram for that connector so I can repin it to the USDM harness

 

You can pull the upper intake manifold and TB and make the JDM harness fit. I routed mine to go under the manifold and out the back along the firewall. It's a tight fit under the manifold but it will reach if you go under the intercooler bracket. And you can probably get a N/A harness and pull the wiper wires from it and add them to your JDM harness so you don't have to repin. Not 100% sure if you can do this with a N/A to TII harness but I know you can take the wiper wires from a s4 and put them on a s5 harness to make a s4 car with a s5 engine work with wipers.

 

Thanks man that helps alot, everyone ive been asking is just saying, GET AN N/A HARNESS,

 

Yeah I went through the same thing......I think the harnesses are the same length just wrapped differently lol If you get stuck pm me and I'll pm you some pics on how I got it to reach when I get the time.

 

alright will do, if you do have the pictures that would greatly be appreciated. I deleted the emissions on the engine yesterday so the Rats nest is gone!! so that should make re routing things a bit easier as well.

Also, so that that second plug on the USDM harness in the car is only for wiper stuff?

 

I am installing a s5 jdm turbo wiring harness into a s2 and need the wiring diagram for this connector. I have the usdm wiring diagrams but this connector is different so i need the wiring diagram for this connector.
