Anyone have a 1994 Cutlass Supreme service manual?

[3100 MPFI]

SPECIFICALLY the Cutlass Supreme.

I need the wiring pinout for the C202 connector. It has to be the Cutlass Supreme seeing that the 1994 has the newer steering column, but the older dash.

Thanks.

Looks like he beat me to it Ive got one for a 1994 if you need anything

Thanks, but any chance of getting bigger scans? That second one is too small for me to read.

Thanks


EDITED:

I don't need the first one (the one that has the connector face on it). I was able to get the info out of that scan, but that second one, I can't read it when I blow it up.

Sorry... I forgot all about this thread and don't know why that is so small. Let's try again.

[3100 MPFI]

Thanks.

Thanks. Comparing the 2, it looks like the 1996 has wires added for the BTSI, and then it looks like 2 wires might be switched around. That seems to be the only difference between 1994 and 1996.

Thanks again.

You're welcome Taylor... Let me know if you need any others as I have access to all the data for a '94 3.4 Cutlass.

I just hope the C202 is the same between the 3.4 and the 3100.

I am doing an OBD2 conversion to my 1988 Cutlass Supreme, and the easiest way to get the interior up to OBD2 specs is swapping in the 1994 Cutlass Supreme dash harness. Getting the steering column was going to be an issue, but seeing the wiring is pretty much the same, that means I can use any 1994-1996 steering column in my 1988 and get it to work with the 1994 dash wiring.

Thanks again. If I need more, I will PM you.

If you don't mind, can I get 1 more pinout diagram?

Can I get one for the C100 firewall connector for the 3.4 DOHC (also for the 1994 Cutlass Supreme).

Thanks again.

[CNCguy]

Not a problem... happy to help.

[3100 MPFI]

Thanks. One more question.

Is the C100 connector the same between the 3100 SFI, and the 3.4 DOHC?

If I get a dash harness out of a 3.4 DOHC, will it work in a 3100 car?

I am trying to make the OBD2 conversion in my 1988 as painless as possible. In order to do this (with a swapped in 3100 SFI), I am just going to convert the dash to the 1994 style. That is the older FLAT DASH but a 3100, so it is basically OBD2 ready.

I am going to a yard on saturday to get a dash harness (I already have the complete 1996 3100 SFI engine harness). If there is not a 1994 3100 car (that is fully loaded), then I want to look for a twin cam.

There is not too many 3100 Cutlass Supreme's that have the automatic climate control, steering wheel controls, and HUD, but there are a lot of twin cam ones that do. I don't mind adding some things, but I would prefer NOT to do the Automatic Climate Control..... Once was enough.

Thanks again.

I might be able to compare the two for you today later on.

I went to see Jay (neversatisfied and manicmechanic are his screennames) this weekend. He brought me his 1994 service manual and I was able to scan what I needed.

We also went to a junkyard, and I got an assload of things.
