First off, welcome to iRV2!
Second, you should add a "signature" to your profile. It contains whatever info you want; most people put info about their coach there, so they don't have to type it into each message. Instructions for adding a signature are here
I have a wiring diagram set for the 2004 Neptune. Send me a private message that includes your e-mail address. I'll send a copy of the wiring diagram set to that e-mail address. To send a private message, click on my name ("l1v3fr33ord1") in the yellow box to the left. This will pop down a menu. Select "Send a private message to..." Do not put your e-mail address in a post (that is, here)- you don't want spammers to get ahold of it.
