WTB: Heads up Display from Grand Prix (Page 1/1) Matthew_Fiero JUL 10, 09:17 AM Looking for a heads up display unit from a 1994 to 1996 Grand Prix. I had one for so many years and now when I go to look into integrating this into the Fiero it's no where to be seen. Thank you! Matthew cartercarbaficionado JUL 25, 07:39 AM mine just broke a few days ago (huge hole in the circuit board from a component failing) you can use a 2001 unit as it's a similar wiring to the 96 and much much easier to find. another option is a 93-94 pldsmobile bravada with the compass display which is an obd1 part so that should integrate right in with no issues. there's alot of driver information units that gm made that could work with the fiero ecu. also just look for early w body dic units in general. like Berettas, Monte Carlo, even some Isuzu models Matthew_Fiero JUL 29, 09:48 PM quote Originally posted by cartercarbaficionado: mine just broke a few days ago (huge hole in the circuit board from a component failing) you can use a 2001 unit as it's a similar wiring to the 96 and much much easier to find. another option is a 93-94 pldsmobile bravada with the compass display which is an obd1 part so that should integrate right in with no issues. there's alot of driver information units that gm made that could work with the fiero ecu. also just look for early w body dic units in general. like Berettas, Monte Carlo, even some Isuzu models Thank you for sharing this and I'm sorry to hear yours broke. Are you going to be replacing it? I am running OBDII on a 3800SC so perhaps the 1997 to 2003 model would also work for me. rbell2915 SEP 14, 07:24 AM Do you still need this? I visit the yard from time to time and can keep a lookout. I did grab one for the same project, the housing is massive. You'd likely need to remove everything so it's just the circuit board and the display without the mirrors.
