View Full Version : VVTi Jap-Spec RLTC fitting

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....

Mine definitely matched this one when I did it.

FR+ A21-3 (red)
FL+ A21-8 (white)
RR+ A20-10 (blue)
RL+ A20-22 (purple)

Maybe difference between input/output?

Mine, same as yours Pete. :)

ABS Connections VVTI

I've checked with my multimeter and they are correct. :eyebrows:

Small Plug
Pin 3 Red wire .......Front Right Wheel
Pin 8 White wire......Front Left Wheel

Large Plug
Pin 10 Blue Wire......Rear Right Wheel
Pin 22 Purple Wire....Rear Left Wheel


These are on my Oct 97 VVTI, I would be surprised if they were different on your 98 car.
I checked the colours on the Injectors themselves to obtain this.

Yup - that's the ECU one too.

Pete - I had the photos etc and wiring diagrams you posted but mine was just a completely different unit.

NB my ABS unit matched the wiring diagrams Martin (mkivstore) sent me.

So there we have it - the full range of VVTi ABS and ECU wiring diagrams.

Any chance of shifting this thread and pinning it?
