Will this work for any newer PCMs?

[Mike_Levy]

I was going through some old Emails and found the off board pinouts for the OBD-2 to PCM hookups for my old 2000 GTP. Will this circuit/module work on any newer PCMs? I used to have software so I could write to the PCMs, but that became worthless once I upgraded from Win95.

I know the PCM connectors for late models are different, but maybe I can adapt this in some way. I do still have the hardware.

I dnt know that I am following your question 100%...but, no.

for example, PIN 2 is the class2 PIN, for most pre-05 J1850/class2 GMs (non CAN), and the CAN pin (6 or 14) would need to be enabled to talk to a newer vehicle, then theres the question of the tool having CAN protocal, which is not likely.

So its all worthless unless I buy another old GM. Thats what I figured. I can toss it all out.

ebay man, one mans junk is....you know

Its a big mess of spaghetti. Nobody is gonna want it.

Maybe I'll clean it up, get rid of all the extra wires, solder and heat shrink the connectors and put some conduit over it all. Just try to make it look better, before I try to sell it. This was one of my first electronic projects, and it shows.
