Hey guys! just wanted to show you guys what ive been working on.
Recently had a dilemma of buying a brz 2015 vs 2017 limited. but what i loved more on the newer model was the cluster looked a bit more updated. so i looked around and some people claimed it could some said you had to reprogram the cluster ... so i wanted to show you guys my findings as best as i could.
So if you want to do this switch and make it look as stock as possible, you will need to buy the cluster, the new steering wheel, airbag ( slightly different fitment from 13-16 vs 17-today), new clock spring. and any plugs associated to it (re-pining might be needed). so it can get expensive if you want to do this conversation.
Now to the question that alot of people have the issue when replacing a new cluster... If you have a turn key car (not a push start), the instrument cluster is part of the immobilizer system. When you replace a cluster, according to toyota TIS, if you are replacing with a brand new cluster, as long as you have everything else the same (BCM, KEY, ECU) it is pretty easy to program the cluster to the car using techstream. But it did not mention anything about used clusters. But according to some reports, some cars dont start when switching their cluster out on a turn key. Thus i think i can come to a conclusion that regular techstream cant program a used cluster to a different car.
(unless in the future i find out if it we can make the cluster "virgin" by reflashing the eeprom.)
This lead me to my first question if anyone can answer... These new cluster with the LCD on them, are they only in models that have push start? because.. it that is so. The cluster was never "binded" to a car because there is no need to.. would it mean they are still "virgins" in the sense there is no immo code stored into it.
Now for push start cars its almost plug in play. no issues.
brz or gt86 it worked fine.

So! Now for the next thing. We have to get the directional pad that's usually in the steering wheel ive worked the resistance on the buttons in order to get something going. If any of you have any suggestions where to put the buttons at let me know. I do have a 3d printer .. so if we have to make custom plastic pieces i dont mind.
So im trying to make it as simple as possible. disconnect the old cluster.. add two extra pins in the back of the connector.. and connect the third cable to ground.
Im also thinking of using tese small 5way directional switches.. but there will be a extra button for the "back button that needs to be there as a second thing.

Any thoughts guys?
BTW does anyone have a BRZ 2017 cluster that would want to switch with mine? My OCD when turning on/off the car and seeing the 86 logo on a BRZ is weird lol. (or prehaps if i get a brz i could see if the setting for brz/gt86 are just a BIT flip on the eeprom or something.)
EDIT: its is a 2K resistor not 2.2 corrected it.
