Using a 95-98 ECU in a 99

Using a 95-98 ECU in a 99
Okay, so we all know there's no ECU upgrade for the 99s, because 99s use the same style harness on the ECU as the 2k and 2k1 ECUs. So someone suggested making an "adaptor" that would be used in the middle so that you could hook up a 95-98 ECU to a 99.
Well my MEVI is quite lonely without an ECU and I'm not real hopeful about any other options, so I'm going to try and tackle this project.
Question 1
Am I dreaming here? Can this really be done? It sounds like I need to figure out what all the pins do on the 95-98 ECU, figure out what all the pins do on a 99 ECU, then make an adaptor and splice together the associated pins. In the end I don't care if I have a CEL and a bunch of codes, I just want my lowend/midrange torque back and an extra few hundred RPM.
Question 2
Is this the connector for a 95-98 ECU?
And this the connector for the 99-2k1 ECU?
Question 3
Does anyone have an electronic version of the 99-2k1 FSM?

Sucks for me and oter 97's, but if I ever get the ecu, the CEL will not bother me.

The biggest hurdle I'd see in doing this is the NVIS. ECU's before 99 have nothing in them for it. On solution that I've heard (from Jime's son actcually) was to replace the key cylinder with a non-NVIS one, get a new non-NVIS key cut, and use a pre-99, non-NVIS ECU.
May work.
May work.

Someone posted a link for the 99 FSM a month ago and I downloaded it. Who knows if it's still up on the web. I have the whole thing on my HD if you still want it, JeffesonM, although someone mentioned that this version (off a CD) may not be the full FSM that dealers have. It seems pretty comprehensive to me, but what do I know. PM me and I could send it to you over AIM. BTW, it just says Maxima A32 but it says ©1998 so I assume it covers the 1999 model year)
