6.0/80e to 5.3/80e Swap

Hey, guys!
I'll start by giving a little background before asking my questions..


I have a 2000 Jeep Wrangeler I did a swap about 5 years ago. It has a 2005 6.0/80e combo (4x4) out of a Chevy van 3500 (cammed, springs, etc). The PCM was dyno tuned by a professional shop.
I also have a 2000 5.3 (have an extra 80e to combo 4x2) out of a Chevy Silverado that's completely stock. I want to pull the 6.0 out of the Jeep and install into a 1985 Chevy c20 and install the 5.3 into the Jeep and sell the Jeep.
My intention is to pull the 6.0 and use the existing harness for the 5.3. The 6.0 will be controlled by a Holley TerminatorX.


My questions are as follows:
1) Can I use the 2005 harness for the 2000?
2) If not, is it just a different pinout situation?
3) Does anyone have a bin file for the 2000 5.3 with 4x4 80e segment swapped?
4) I have a 2001 bin with 5.3/80e already swapped. Can I use that with the 2000 PCM


I hope y'all have good news for me!
Thank you in advance for the helping hand.
Same question asked in another forum. In case someone gets deja vu. :innocent2:
