thanks, but I still have another question, please tell me what do you think,

I've done some research and seems like the module that I need was meant for Oldsmobile and Pontiac cars that never showed up in this shores, so no luck finding them here, the only 5 pin module available is the one that came in 81 and later Blazer and Pickups with the ESC system which uses a knock sensor and a retard/control box.

Do you think that one would do the same? what kind of input does this 5th pin takes? or is it an output terminal for the ESC box?

I tend to think that the ESC box picks up the signal from the knock sensor then sends a + or - signal to the module in order to retard the timing, but I might be wrong, if this was the case then this module would work for my project same as the Olds module would, I don't know how this system works, could you help me?
