Re: 1990 valet key Vs 1991
the 1990 is a totally different key design and code in the ECM, you turn to full power the key stays there. On the 1991 and newer the key snaps back after you turn on full power. the key setup on a 91-newer is a module with a light.
you would need to figure out how to have the momentary key, set a latch for power all the time. Can it be done sure, but most here want original, if you don't care about the letters showing full power the 1990 bezels are easy to make from a normal bezel

Ah...ok...I understand the differences... It's seems like I need a relay that keep the signal when the key is turn on full power...but this is only an idea... I'll like to put zr1 bezel because there are the Yellow letters on it... Or...I can use my key in the new radio bezel...but I know that this need some modify...I think 1991 key hole is bigger than 90... So...thanks for informations!! |

I would need to confirm the 1990 key voltage but I am thinking a 1991 key assembly with a small Arduino could work with some software skills to program the Arduino. How much are you looking to spend on the bezel?

Re: 1990 valet key Vs 1991
Buongiorno Max, if you want I can ask in the German forum if someone has a spare bezel for you. I'd be surprised if anyone had... But it's worth a try.
Otherwise why don't you buy from a source in the US? Shipping shouldn't be too expensive for that piece and to my experience prices and availability are WAY better... Sent from my J9110 using ZR-1 Net Registry mobile app

Re: 1990 valet key Vs 1991
Can you epoxy the 90 key/switch assembly into the 91 Bezel?
