What harness goes to which plug on the PCM? 
I feel like an idiot asking this but just want to make sure before i plug and fire her up. Which harness goes to which plug on the pcm. I know that one harness is blue and one is red, which goes to the plug closest to the firewall?

Can't tell you on your type of car, but all the PCM's I've seen have the word BLUE and RED on the exposed connectors.
I don't mean for this to be a smart **** reply, I've just changed a few PCM's recently and thought it might help ya out quickly
Cheers,
