The wiring diagram (as well as the entire service manual) is available for $20 at
http://www.nissan-techinfo.com/infiniti with the one day viewing subscription. You can download it as a .pdf and take it to your installer. Might work as a good "weeder" for the installer too - if he doesn't have a laptop or isn't computer literate enough to use a service manual on a CD ROM, he doesn't need to be working on an M45!
My guess is that you could add just the remote start option (DEI makes this, or at least used to) and maybe use the "panic" button on the factory remote to control it. You'd loose the "panic" feature, but you'd avoid having multiple remotes... I have my Viper 550ESP working in conjunction with the factory alarm. Took me a week or two to get everything the way I wanted it, but it's great. Of course we're talking about flashlights vs. lasers in the comparison of a 1990Q and a 2003M as far as the electrical complexity, so the install will definately be different!
