converting to dual plug ecu(99) and also adding in the dash harness from 99. cant figure out how to connect the 2 rear harnesses(95) to the 99 dash harness. any help would be appreciated

also the 95 has a key light and an ashtray light. but the 99 harness doesnt (or the timer in the fuse block) any way to add these on before i put the dash harness back in
