91 da with stand alone obd1 harness. Harness has plugs for computer dist. Coolant temp injectors iac map tps and alternator and a few ground wires to ring terminal. This is a circle track car so has no dash or cluster. Obviously there is no speed sensor wired into the harness but there is 1 wire from computer plug that is a vss pin just has a short wire coming from it. Do i neex to worry about this if xomputer is chipped and vss is deleted
