sr20det electrical problem....interior stuff

[the3SecondJerk]

Ok, heres the story. I put a 1994 blacktop into a 1989 240sx coupe. It runs fine...for the most part more on that in another post....but! The interior is screwed up. The turn signals go crazy when I turn them on, the reverse lights dont work, my stereo doesnt turn on, lights come on and off at will. What the heck? Anyone have any clues?

Thanks
Dan
