Just for the record, some advice for fitting RLTC to the J-Spec VVTi.
There have been a couple of threads on this, but my ABS unit was different to the ones that have been posted up before - my larger side of the unit had 22 pins as opposed to the 26 that most other people have found.
Below is the picture of the ABS unit and where the wires go/which wheels they relate to.
Best advice I could give is to test by plugging in a multimeter and spinning the wheels. Then, once fitted up, before you put everything back together, plug the computer in and spin each wheel again (and do the revs) to check it is registering on the RLTC software. Bit of overkill but didn't want to find out it was wrong/not registering having put everything back together!
On the ECU, the wiring was as in the other posts, the main point being that the injectors are wired in sequential order (654321) rather than the order 432165 as per the published wiring diagram.
Hope that helps someone in the future.
To clarify the ABS wiring is:
A-3 (Red)
A-19 (White)
B-1
B-3
Not sure what the last 2 colours were - Emin, do you remember? It was down as purple/purple on the wiring diagram if you recall....
