im using a n332 ecu
do any one have re wiring info???

Check the FAQ stickied at the top of this board.

tried searching cant find anything
all i found was for a s4 t2 into s4 chassis

I dont think its possible. You will need a S5 harness, n/a or turbo.
One reason why I think its not possible (or just harder) is that the maf wiring, the tps wiring, and many emissions wiring (unless you are taking them out) are different from S4 to S5. They will not work.
And when you go with S5 harness, you will need S5 ecu.
As for the interior harness, If switching from S4 to S5 ecu you will probably need the S5 interior harness also. Not pretty sure.

That will help you out immensely

You didn't search well enough. It is pointless to use the harness from the turbo car. Stick with the n/a ecu.

Not impossible but not really worth it either.

Why use the n/a ecu? Isnt the timing and fuel maps different. And yes im to lazy to search.

Nevermind.

Hmm knew i wasnt crazy. haha

you will be fine. the only rewire you may have to do with with injector impedance.

make sure to get n318 air flow meter and pressure sensor.

+1 And S4 T2 front cover, S4 T2 injectors, S4 T2 throttle body, S4 TPS. If im wrong then please inform me. - Nick

i bought the car with this swap already in and running
had to change the whole interior harness
so im guessing yes

but we both could be wrong...

MANSU_V36

yeah i have the n318 afm,i have to double check the pressure sensor

is there any write-ups on how to rewire the injector impedance????
could u please send me a link

Wouldn't it be so much easier using an S5 T2 harness and ecu? I don't understand why FC owners cheap out so badly... its sad.

need RX7

None of that would match up with the rest of the car's wiring. There's a reason no one does cross-series swaps, and it's not cost.

OP, get a standalone and end all these headaches.

It's generally easier to use the N/A wiring harness since they have the alternator wiring. TII's on the other hand don't, since the alternator wiring is located on the chassis harness.

I started the same exact swap and then stopped midway and bought a standalone. Its not remotely cost-effective, its a waste of time and there are absolutely no advantages to attempt wiring it in to the existing harness. Plus i remember the harness needed to be stretched like another 3ft to reach the ecu. And it took me a couple months to get useful diagrams because i had to find them already translated. Go out and buy a cheap microtech or haltech and save urself a lot of problems.

Good Luck

MANSU_V36

the engine harness is already been stretched
is only gonna be my daily so im not looking at spending a lot of money

thanks

is there any way around this....

i didn't know about the fp relay. to me the easiest way to check would be to see if it plugs in to the ECU.

MANSU_V36

u mean the harness??
yes it plugs right into the ecu

MANSU_V36

someone help me
im about to go ballistic,im about to burn her down

is it even possible to get it running in this situation

or im better off searching for S4 NA harness???

Patience, my friend. Are you swapping the interior harness to s5 or s4?
