well the forst thing I would do is NOT even attempt this. your non digital setup is not wired at all for this so EVERYTHING in the system would need to be changed because the digital uses a logic board and the other does not. unless your a very good engineer or plan to redo all the wiring to make it acceptible for computer components i would say just leave well enough alone. many streetrodders use modern digital in the rods but its real difficult unless you have an new harness or alot of friends with patience. if you insist on this project maybe try to find another truck that was totalled and maybe you can get the harness. good luck.
