Not relevant for NSS swapping, but the later TCUs also seem to have an input for the reverse lights that the earlier setup didn't have.
oops, thanks, missed that. I'lll update it shortly... I've been meaning to put this together for a while now, just managed to find the time last night.

I have considered this... I am not sure, but I think it will work. Hoping I can find a reasonably priced 97 TCU and get it before the snow melts from around my 98 so I can test this out.
