Hey to all you FWD fellas out there....

I've got a '94 855 turbo and my tranny is shifting very early and is telling me that I have no voltage to my mode selector switch. Also... my power mirrors aren't functioning nor are the lights on the gear selector or the lights for the heated seat switches. My question then is this... Is there a shared hot or ground wire for that entire lot? I've already checked the fuses and they are fine. One more issue is that when I hold it in L range it will go like hell in first but just smack the rev limiter and not shift into second unless I put it up into 3'rd, but then it hits second for like a second and then goes directly into 3rd! I was reading the diagnosis proceedures in the Volvo service manual that I downloaded and it says something about checking to be sure that it will shift into second when the selector is in low, but it doesn't say anything about what it means if it doesn't! HELP!
