Here is some VALUABLE info (non-HR):
ECU's
Automatic:
03-04 "DE" [4 pin o2][AVOID 03 G35 sedan ECU *COUPE ECU ARE OK*]
04.5-05 "DE" [5 pin o2]
2006+ "Revup" [5 pin o2]
Manual:
03-04 "DE" [4 pin o2]
04.5 "DE" [5 pin o2]
2005+ "Revup" [5 pin o2]
Harness'
Automatic:
03-04 "DE" [4 pin o2][AVOID 03 G35 sedan harness *COUPE ECU ARE OK*]
04.5-05 "DE" [5 pin o2]
2006+ "Revup" [5 pin o2]
Manual:
03-04 "DE" [4 pin o2]
04.5 "DE" [5 pin o2]
2005+ "Revup" [5 pin o2]
With this being said you can use Any combo of ECU's and Harness as long as o2 sensors match and they belong to the same group "DE" or "Revup".
Examples:
"DE" ECU Harness/O2 on "DE" Block
"DE" ECU/Harness/O2 on "Revup" Block *4 sensors will remain unplugged, but will work fine*
"Revup" ECU/Harness/O2 will only work on "DE" block if the DTC's are disabled
*03 g35 sedan ECU/Harness are that of a Maxima*

AND MUCH MUCH MORE!!!
