I'm surprised AutoZone doesn't sell them. That was their website I sent. Now, when you connect to the trailer and only the signals work, either you have it wired wrong, or something is disconnected.
Do me a favor. Try this: Take a battery charger and connect the negative to the trailer frame where you can get a good ground connection. Then, one wire at a time at the trailer's plug, see if the lights work correctly when you touch the positive side of the charger to the pins. Also, confirm the pins are wired in conjunction with the vehicle's connector.
I'm not sure what kind of a pin you have, but a paper clip will usually work when trying to touch one pin at a time.
Let me know if they are all working and turning on from the correct pin. As far as the reverse light on the vehicle, something was disconnected when you wired it new trailer light package. Recheck the connections that were made.
Also, let me know if the vehicle's lights work even when the trailer is attached.
