My OBD1 DC2 wiring has an orange speed signal wire & there is no blue plugs either just grey.

For OBD1 the speed signal wire is in B10 on the ECU.

For OBD2('96+ DC2) its in C18.

It depends whether your OBD1 or OBD2A,these pics below will help u sort that out by comparing your ECU plugs.

Or u could check your dizzy plugs to quickly determine
OBD1 has 2 dizzy plugs
OBD2 has 1 dizzy plug.
