[max76]

Hi guys,
i have a question for you...
I have a 1990 zr1...may i put the 1991 power key in my car?

no they work totally different.. If you are good with electronics, you could probably make an interface to use the 1991 in the 1990..

What is your reason for the change?

Because the previous owner change the original Bose system and put a new system and the monitor is not a perfect 2 din...so, he modify also the original plastic trim...now I'll like to change radio system and put a really 2 din, but I need a new radio bezel and gear consolle. Here in Italy I found these parts from a 1991 zr1...I'll like to put the 1991 key to do a good job...nobody know how use the 91 key in 90 zr1? What change?

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!!

the mounting for the 1991 vs 1990 is totally different. Also a relay will not work, as you need to latch on then latch off.

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?

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...

Hi Matt...i found the radio bezel here in Italy but it's a 91, the price is very low and the conditions are good. If you want to ask in the deutch forum could be an alternative...
I look on ebay.com but there aren't zr1 radio bezel for sale...but i think price and shipping are so high...(i need radio bezel and gear consolle)

I don't know the prices...

Can you epoxy the 90 key/switch assembly into the 91 Bezel?
