Swap Guys, ECU Question, AEM EMS Specific Related Options

[Fastbird]

How easy would it be to repin my 92+ Computer to a 90-91 pinout for use with an AEM 1120 computer instead of the 1121? Reason I ask is that I may have an opportunity to snag an 1120 for much cheaper than the current going $1500-1600. If it's not a total rectal tear to do I would probably go this route in lieu of paying full price for a 1121 AEM EMS.

Ok guys, help me out here. Above you can see my quick pinout chart. I have highlighted some blocks in red between the ST185 early computer (2nd listed) and my computer (1st listed).

Any guidance or direction for me? Remember that I'm trying to repin a LATE computer to plug into an AEM 1120 computer for an EARLY computer.

*Edit* I'm a tool. I just realized that OF COURSE my computer would resemble the late SW20 computer. But......for the repin, I still have the pins in red that don't match up with each other and I have no idea what they are and if they need to be moved or left alone, or if it's even doable.

I think you have the first two labeled backwards. The top one is JDM, the second one is USDM

T = check connector signal (jumper to GND to check error codes)
TE1 = check connector signal (jumper to GND to check error codes)
TE2 = check connector signal
OX = Oxygen sensor signal (before cat, single O2 motors)
OX1 = Oxygen sensor signal (before cat, dual O2 motors)
OX2 = Oxygen sensor signal (after cat, dual O2 motors)
THG = JDM exhaust gas temp switch, can be left open (shorted to ground lights warning light on dash and puts ECU in limp mode)

For your purposes:
T = TE1
OX = OX1
all others can be left disconnected
