Converted from 98 to 99+ PCM... EFILive Will Not Connect! Help Alright, I think I may have wasted my PCM, but I figured I'd see what everyone else thinks first. In my first attempt at testing my conversion, there was a MAJOR problem. Apparently I got confused with the write up on converting the pins, and ended up leaving 3 of them in the same spot, but the 3 that were left in should have been swapped over to the opposite connector of where I had them. The wires that were supposed to be moved that were not...
PCM Connector C1 BLUE (left in RED): 20 ORN: Battery Positive Voltage
PCM Connector C1 BLUE (left in RED): 19 PNK: Ignition 1 Voltage
PCM Connector C1 BLUE (left in RED): 58 PPL: ECM/PCM/VCM Class 2 Serial Data
Oops. I'm just lucky I didn't completely whipe out my FlashScan.
So on my first attempt, the FlashScan went nuts and ended up toasting (litterally smoking) the OBD2 cable where it plugs into the scanner... well I managed to fix that, tested that my scanner still worked on my truck, and proceeded to track down my mistake. So I found my mistake (as stated above), hooked up the FlashScan to the OBD2 port, and it turned on, and seemed fine... I turned the ignition key to On, and everything still seemed okay. Plugged into the laptop, and cannot for the life of me get EFILive to "Okay" the status on the PCM for me to download the tune off of it. The car is torn apart for the winter while I work on the motor, so yes, there are a lot of things unplugged, but I was able to download the tune off of my old PCM with the car being in the same status.
Does anybody have any idea what might be the deal? Do you think I toasted the PCM in my first attempt after I gave it power from the battery?
Would a blown fuse somewhere keep me from being able to "Okay" the status in EFILive? What fuse would I have to check?
Any help is greatly appreciated. Thanks guys! Sorry for my stupidity.

Guess I should have checked the fuses first... found that PCM BAT fuse was blown... replaced it and "Status OK" in EFILive. Excellent!! Thanks to everyone that at least read the thread.
