Tyre Pressure Monitoring System After-fit

My R3 is a standard UK model that comes without TPMS.

I acquired a while back an R3 instrument cluster with TPMS for a project car that I now no longer have.

Fitting an aftermarket stand-alone TPMS is probably my best option if I want it. However, I want to at least investigate the other cluster.

Can anyone please help with info on whether or not I can fit this and get the TPMS working, for example:
@ Will the rest of the system be the same?
@ Will non-Mazda sensors work and, if so, are they here any valve cap sensors?

The TPMS module is separate from the instrument cluster. Did that come with the cluster?

Thanks.

The block diagrams I have for the TPMS are taken from a Series II servicing manual (2011 - RX-8). It shows the TPMS sensors communicating with the keyless receiver, not a separate TPMS module, although I had expected to see one.

Perhaps I am being misled by the S1 term 'keyless receiver' that I see in the S1 wiring diagrams (see attached). I understand that in the S1 the keyless receiver communicates with the key fob for locking and unlocking.

Which is still separate from the cluster.

If you need the module from an R3, I am sure I have it.

Correct. However, my point was around a different, separate, TPMS module rather than the 'keyless receiver' that all S1s have.
If you need the module from an R3, I am sure I have it.
Thanks. However, I'm in the UK and I'm really asking for someone else with an S1, so that won't be worth the effort.

So I'm actually doing this now, and it's a pain in the butt. To answer your question, no the simple replacing the cluster with a TPMS enabled cluster does not work. I'm going through to see what is required now, it's either 1 of 2 options. First option, enable the TPMS option/system in the PCM, this would be my favorite solution. And at some point I will have this answer. Second option, and the most realistic option, replace all of the computers in the car from a matching set. This option cost me around $200 on ebay. It's all of the electronics that you need to run the car and matching so the immobilizer / security system doesn't shut you down.

When I have a full solution I'll be sure to post it here. This is something I must do in order to register a car form Canada in the US btw.

That's one of my random questions answered. Thanks!

I was looking into the option, but the main problem being odometer mileage, which I don't want to mess with. That's why I just decided to just buy a set of aftermarket TPMS in the future.

Give me a few days.. found out some more info that I may have a super easy solution for you. No coding required and all factory stuff. But I won't know till probably mid next week for sure. And the odometer thing I agree with. I have to have a solution for that as well.
