well, if you take off the plastic that covers the ignition stuff,its prety straight foward. You should see everything that needs to be done just by looking at it. The toughest part for me was the remainders of the breakaway bolts. They're almost like rivits, so either a dremel with cutting wheel or a hammer and chisle are needed.
From there, once everything is off up top, just follow the wire harness to the fuse box under the dash and disconnect the plugs.
But always have your helms there for reference just incase. I had Alldata for refrence, but like i said, its straight foward and i dont think you should have any trouble
here's a scan from the Honda CRX service manual
