I remember( rickady88gt )'s ride.. I think it was a 3.5L but a Malibu instrument cluster?... I saw it at westfest back 12 or so years ago [This message has been edited by unboundmo (edited 01-24-2018).]

I know.. 3 long years..
I have the device working. I made a module to convert fiero wiring into Riviera instrument panel serial data.. call it the Fiero BCM.
It is all working on the bench. A few of the fellows on the forum have shown interest in the next step, that of fitting and wiring it into a car.
I am linking here a video, and a PDF..
The PDF is a wiring diagram of how the BCM and Riviera IPC would wire into a Fiero.
Working..
Speedo, tach, fuel level, coolant temp, oil pressure, door ajar, high beam, turn signals, fasten belts(?) brakes on, SES.
Done but not tested are:
light dimming.. a function of the Riviera panel. The transistor will be removed from the Fiero to allow this to work. Speedo and tach not yet tried on a car.
Not implemented yet:
Receiving data from the ECM, and no software yet for the OBDII port.

FYI, mixing tin and gold contacts is not recommended.
Stick with gold-on-gold or tin-on-tin.
What kind of enclosure will the board go into / where should said enclosure be installed?

An update on this project..
I have the circuit board fully operating and programmed.
Cajun has been working on mechanical fitment on his end, and is getting close.
The final solution includes some stuff that Cajun needed.. cruise, resume, and some other stuff.
The speedo and tach are working, and there is an odometer. The trip odo does not work.
There are three buttons on the circuit board to set the odometer and tach cylinders, and it stores that in non volatile memory.
There is no software yet for ALDL or OBDII.
So far so good, we will get some pictures taken next.
