Hey,

I run:
INJ1 (Cyl1) - 4U - output 1
INJ2 (Cyl3) - 4W - output 2
INJ3 (Cyl4) - 4V - output 3
INJ4 (Cyl2) - 4X - output 4

On page 9:

INJ1 (Cyl1) - 4U - output 1
INJ2 (Cyl3) - 4W - output 2
INJ3 (Cyl4) - 4X - output 3
INJ4 (Cyl2) - 4V - output 4


What do you think ?

 

I think you should confirm it with a multimeter. Should take you about 30 seconds.

 

I'd do U-W-X-V


4X is cly 4.

 

Just made a test with TS,

INJ1 (Cyl1) - 4U - output 1 - checked
INJ2 (Cyl3) - 4W - output 2 - checked
INJ3 (Cyl4) - 4V - output 3 - inj 3 in the test shoot cyl 2
INJ4 (Cyl2) - 4X - output 4 - inj 4 in the test shoot cyl 4

So that is why Iget high EGT @ cruise...

damn, I got the data from DIY, I drive one yaer like that :\

 

For future reference, I've attached the relevant pages of the factory wiring diagram here. I trust it far more than aftermarket documentation (and it's far easier to read).
