Back when I had my 2000 Camaro SS, I wanted a HUD. So I built one. You just plug it in to the OBD-II port and set it on your dash. No cutting or splicing. I'm making all the plans free for anyone to use as I'm not too interested in selling them. I'd rather "give it to the people" than have it go to waste. It's not an overnight DIY project; you need some serious skill to make one of these.
It does a whole lot more besides showing PIDs and has a 16-key keypad and USB interface. Check it out.
It should work with almost any 1996 and later GM car (any VPW based communications protocol).
Here's the site with all the info and downloads on how you can build one. Please share it with your friends.
