Default Harness/pcm?

Heres the potential problem. I have the 09354896(16220610) pcm. And the harness i have is from a truck and it has the blue and green connectors. I've researched the pcm # and found that its compatible with 99-02 cars, and trucks. The guy who modded the harness and did the mail tune for the pcm informed me that both were for a dbw application, but that he could convert them over to dbc which I preferred. My project is too far off for me to test the harness and pcm on the engine to verify that they are properly pinned to one another. So does anyone have a way of bench testing the harnesses and pcm?

Use a multimeter and test a few circuits that changed from red/blue to green/blue

I didnt think the 4896 PCMs were DBW compatible. Compare to a 99-00 C5 PCM. If the service number is the same youll have no trouble DBW or DBC

Default I agree with Pocket

I think Pocket is correct. The 896 is not a compatible DBW PCM. Only the 411s were used for DBW (on Red/Blue Applications).

Regarding the harness, get a schematic and multimeter and start checking pins.
