While it's one of my old ideas that never came to fruition, another mr2 owner attempted it. This is just my take on my approach to it.
I'm starting with the Modelista cluster which is similar to the TRD but has zero accent with the all black and sleek theme.
Why use this cluster?
1. It's in KM which is perfect for canada, it still 40km lower than my 260km canadian cluster but it's not like i'll hit that speed any time soon.
2. 10krpm redline ooh baby. I plan to have another v6 build for hi compression and higher red line
3. oem oil pressure gauge
4. the cluster takes very little space leaving room to put a couple of gauges on the side and even a digital bar where the trouble shooting indicators are.
Now for the bad part
1. the altezza/is300 uses the old school rpm feed and it comming from the igniter
2. since the tachometer is ignitor based, it's also reads the 3sge black top cycle (will work for 4cyl w/ no mods) so it will need to be modified to work for the v6.
3. majority of the function aside for RPM and speedometer it's operated by the canbus/multiplex. I may have to run a body ecu like the stock or hijack the needle modules directly.
4. odometer a bit of an unknown to where it stores the data (maybe in the engine ecu). it will require some research how to get it to sinc with my mileage
I've collected the diagrams so i'll have to do a pin out. My plan to keep it clean is by keeping the whole back side of the mr2 membrane so i can keep the harness (no hacking). In the simplest way i'll be using the module bolt holes and bulb sockets as the wiring source for the cluster using my spare LED harness.
Just like my original cluster i will do the same to it
Some burrowed images, im still waiting for mine in the mail
