Swap digital dash into TBI

Swap digital dash into TBI
This has been an on-off-on-... thing for a long time. I'm toying with the idea of swapping an 86-88 digital dash into my 1991 Firebird. The car has an L03 TBI auto engine.
I believe it wouldn't matter if it's TBI or TPI or manual/auto?
Can anyone confirm on that?

Re: Swap digital dash into TBI
I do not believe you can get the digital dash with the TBI. The only cars I have seen with the Digital Dash were TPI cars, And they were always Trans Am/GTA cars. I know that the 85-86 cars had different electrical connections here and there compared to the 87-92 cars. Overall anything is possible BUT this will be quite the big undertaking to do so. Not to mention the sheer amount of parts your are going to have to find. Just to start you car going to need, The dash, the AC controller, interior bezels, spare TBI,LB9 interior and engine harness(so you can cut them up and not destroy the one that is in your car). You car probably gonna spend around $1000 just getting this project started. I am adding the Bose system from the later year Camaros to my 86 Bird. I have everything but a spare uq7 wiring harness. So your not the only one who is getting into stuff like this lol.

Well. You are going to have to take apart the whole wiring harness for your whole car and modify it. Sure, some things will most likely be easy. But if im not mistaken the digital dash cars also had indicators that told you if the door were open etc. Its going to be one of those projects thats gonna take up your whole basement because all the trial and error/ the sheer amount of organization just trying to keep track of what goes where.

Yes, the tach was changed in 87 from a S type style to a more round one. But apart from that there should be no difference, at least in the electronics. Not totally sure though... I have a 86 and an 88 tach display laying around...
Anyway. I think I'm going for it. I like insane projects. I'm gonna read into the internals and post, if anyone is interested.

The digital dash on the Trans Am was not limited to the TPI engines. The parts book shows part numbers for the cluster for H, E versions of the 5.0L. Some of the early clusters have a choke sign instead of the Service Engine Soon lamp.

According to the Parts book, the digital dash for the 5.0L TPI (F) Auto and 5.0L TBI (E) was the same in 1988:
Unfortunately, production numbers aren't publicly available for this year and for non-GTAs. On the GTA side, the digital cluster represented slightly over half of all GTA sales in 1988 making it a very common option - atleast on the GTA in 1988.

Re: Swap digital dash into TBI
Thanks guys, this information is extremely interesting!
Currently scanning ebay and craigslist for TBI harness. Or does anyone know someone who knows somebody who might know a guy that has heard of someone with a TBI digital dash car and is willing to part it???
