96 ford f150 remote start

im hooking up a remote start on a 96 forf f150 and it says the heat/ac wire is blue/light green at ignition switch there is no blue/light green wire there wondering what color wire i need to tap into to make the heat work and the tach wire says tan / YELLOW at ignition module there is no tan / YELLOW wire present what wire do i need to tap into if someone could help i would greatly appericate it
