89 Vette 160 Baud

[89rose]

I have an 89 vette (1227165/APYP). I looked at the ALDL connector and there is no pin in the "M" position. There is a pin in the "E" position. I am concluding that I need to communicate at 160 baud. Is the correct? If so, what do I use for XDF or ECU file? The 32 and 32xx are for 86 to 88 vettes. Everything for the 89 vettes seems to be for 8192 baud.
Note: ALDL has pins in A,B,C,E,F,G. I confirmed A and B with the "paperclip" to read codes.

Thanks
