ALDL Connector specs on 91 Z28
I'm new here, and say Hello to all f-body guys....
As yet, i'm working with the 7747 and different programms für datalogging and emulation.
But, today I would look inside a 91 Z28 with L98 engine TPI and MAP. This car has a bad idle and problems under heavy load.
I tried to connect the ALDL port with my cable, but the ALDL connector looks different from any description i.e. Autozone. Two rows with six contacts per row. Six contacts are empty, the other ones are loaded. Upper right is black/white and I guess this one is for ground. Going to left, is white/black cable probably test terminal. Next one is grey, followed by two empty contacts. The left on the upper row is a brown/black cable.
In the lower row, the right is orange (serial data?),empty port, purple cable and all others are empty.
Can anyone tell me the specs for the contacts?
I appreciate any help!
