How can I install a CD radio from a 2000 civic into the lower (cassette tape player) compartment in my 1998 civic? What special wiring would I need to keep the keyless entry working in the original radio left in the normal dash position?

 

Why don't you just snag a keyless entry box too and replace the whole mess?

 

Won't work WITH EASE... you'd have to change all the wiring around... Your stock deck has 2 plugs... 1 plug must be left plugged in for the keyless entry, then you just shove your stock deck back behind the dash somewhere.
