Okay i know there are 1 million threads about swaps but ive searched and have been unable to find a difinitve answer.
I bought a rhd 6speedtt clip.

I am swapping into a 95 na auto.
I have all parts to do the swap except i have a a few questions about wiring.

Instead of using the Jdm harness and extending the wires i bought a usdm 6speed tt harness.
In order to use this with the jdm ecu i have to change a few wires around.. First of all what are they and what exactly do i need to change.
2nd if I buy a usdm tt6speed ecu and rail/injectors what else do i need since the usdm is maf based and my motor will have the map setup.
Thanks ahead of time.

I would get the usdm 6spd tt ecm save yourself the headache, also I would recommend getting something like the aem harness extension. That way you can cut/splice your accessories into the harness extension instead of doing it to your brand new 6spd tt engine harness. You can look for a hks vpc (old now) to remove the maf, you can go standalone. Just my thoughts ^_^

Not sure 100% he can just use a 6 speed ECU with that aristo motor. I would check through the pinouts to make sure everything matches and you should be good to go. The only thing that COULD be different is maybe the MAP sensor and a few small odds and ends. Oh and you will need a 6 speed MAF as well.

You can run the JDM ecu on the USDM harness. It's ridiculously simple. The only thing you have to do is take the ground wire and the Air Temp sensor wire out of the MAF plug and run them to the IAT sensor on the intake. The wires you want on the MAF plug are pin 4 (brown w/black stripe) and pin 3 (pink w/blue stripe).

I figured it was simple. Just was waiting for someone to chime in with exactly what needs to be done.

thanks jono if thats all i need to do ill be a happy man, what about that egt sensor that was located in the first cat thats no on a usdm version

 

[JonoTurbo]

I didn't use any egt sensor, and I'm not throwing a check engine light or any codes, so I guess it's not needed. Also, you will have to rewire one of the fusebox plugs since one of the NA ones is 3pin and the TT one is 4. That is needed for all NA - TT swaps though.

what about the injectors i read something about one being high impedence etc.?

 

[JonoTurbo]

Oh yeah, forgot about that. If you want to run the stock 440's, you will have to build a plug to bypass the injector resistor. Basically, all you have to do is connect all 7 of the wires in the injector resistor plug together. I bought a new injector resistor plug and some patch wires from Toyota and built a bypass.

so they all just need to be wired together... can you give me more info on the plug you bought thanks.
