you can find the wiring diagram on jdmfan.com the site is down atm, but a google cache of it is at http://216.239.33.100/search?q=cache...hl=en&ie=UTF-8 i plan on doing it with my car (have the cluster), just gotta get the plugs first. i'm not gonna solder anything, just hook the wires up. a lot easier i think.

now, if you're talking about it not physically fitting, Paul has done it, so you might be about to ask him. but i think it's just a matter of finidng the right spot for it, and maybe cutting something to make room. i don't think it'll ever completely fit in an eg though.
