I just install and prestige aps25kb with keyless entry outputs.  the truck has oem power locks.  i need to know if i need wire in relays.  when i connected the wires to the power door locks nothing happened when i set the alarm.  I tested the outputs and they work so i assume that i need relays.

Thanks for your help
