I remember seeing some previous conversations about putting in newer style HUD in our Gen1's.  THought a re-pin was required.  I picked up an Aztek HUD to install in my 95.  I'm thinking about swapping the components within the housing, but not sure on the wiring swap?

The Aztek and Rendezvous HUDs both rely on serial data in order to read the speed.  I know jack about OBD 1.5, so I'm not sure if it would support it.  You could give it power and connect the data wire to the corresponding pin in the ALDL to see if it works.

The plugs are nothing alike and it would need to be repinned.

I think Taylor used the Aztek HUD in one of his GPs.

EDIT: No, it was for his Cutlass and it didn't work because the Aztek gets the info from the BCM rather than the PCM.

I'm no electrical engineer, but the screen in the newer HUDs is a dot matrix LCD, the old one is an old school VFD display. You would need some way to drive that new screen because the other board won't support it.
