Jon,
What type of Meter did you get? Analog (needle) or Digital... Make sure the leads are plugged into the correst holes for measuring resistance (Ohms) some have another plug in for high voltage or measuring watts. As Bill said, we should be seeing 750 Ohms on most or some of the leads.
Bill's right, those readings are whacked!
Although the open on D is interesting... Is the OEM Radio still plugged in?

No, radio is UNPLUGGED. I am using the negative terminal on the battery as the ground. Should I use a different? Will jump down the meter (it is in OHMs) and submit new readings! Thanks!

The last reading you took for the pink(which goes to the remote lock receiver) appeared to be 2.1 ohms. Is it still the same? If so, that is an issue.

I have lt green and dk green jumped at the moment and am going to drive it to my golf tournament today and see how that goes in reduced engine power. IOf you have any idea per those readings as to what the issue may be... looking like the pink wiring is out of the loop!

Anddddd we're up and running!
Tim called me up on the phone and he advised I yank the Pink wire from the connector and see what it does... well I'll be damned! Everything communicates now! Except the RFA but that's because that's the pink wire obviously!
So it appears I toasted the RFA which was giving me all the trouble.
REALLLLY want to thank everyone who helped me out, Madmatt, Lucky, BC, and of course Tim who all chatted with me extensively and even called me over the phone to narrow this down!
Big thanks!
Oh yeah, and I learned a Sh*t ton about the electrical system and my car in general!

Jon I am glad it is sorted out and the culprit is found.
Will you still need to install the other BCM you picked up?(due to the PINK wires delima)
You guys are too much, I have had help from BILL too and LUCKY has certainly helped in my threads - a big thumbs up for you all
Thanks,Matt

So through this experience, you learned how to troubleshoot and isolate the class 2 serial bus, and learned how to use a meter. As a result, your resistance measurements revealed the pink wire having a abnormal low resistance...and you found it!
Good job Jon

Thanks guys, I learned a TON from you guys. I owe you all a bunch so whenever you need anything just give me a shout!
I do not need the new BCM so I will either keep it as a spare or post it back up for sale

I appears the RFA unit is NOT my issue.....
-HOWEVER a HUGE thanks to Tim for sending me out a RFA to try out, I will get that back in the mail to you, but HUGE thanks, what a guy!
Anyways, I put the good RFA module in, reconnected my pink pin that I have had pulled from the star connector and right back to my issue. reduced power, everything, car won't run. Pulled pink plug again, back to normal with just no control of tire pressure or use of keyless entry..... any ideas?

The PINK wire is your issue. Remove the module and starr bus shorting buss & Measure it to ground and see if it reads INFINITE. If not,,find the short or issue.

You're going to have to follow that wire Jon and see where it's shorting out...
