My new 71 Dart and the issues I am finding. Help needed please

Moparmat2000 - I got it yesterday and the only thing I've done is upload pictures to my personal album on facebook.
I have replaced all fuses, and I will check with the ohm meter tomorrow. I know he had the engine out so grounds could be loose in various places. I'll be looking for loose wires as well. I'm having trouble with the dash (my neck wont allow me to look up under the dash easily). Can i take the seat out and get to it pretty easy?
