GTX Generation II trigger

I just purchased a GTX Generation II trigger foir my Benjamin Trail NP2 rifle. Reading the installation instructions I see that my trigger is not like the one described in the GTX
​instruction sheet. I Called Airguns of Arazona where I purchased the trigger from and was told they could not help me and should post the question of the different triggers on this forum... HELP Thanks Marty
 
In response to my previous post I would like to update it with the following: After a through investigation into my trigger problem I have found the following:
​Airguns of Arizona did send me the trigger that I ordered. I ordered this trigger after I was told by their salesman that it was the right one for my Benjamin Trail NP2 rifle even though I told him I thought I remembered something that I was told the previous week by their salesman that there was a different trigger I might need. He said he spoke to there "GURO" and the GTX trigger was the right the right one. IT WAS NOT. After investigating it on theirs and CharlieDatunas site I discovered that my rifle took two different trigger models depending on which rifle I had.
Well after being told by Airguns of Arizonas tech department that they did not make the trigger and they could not help me solve the problem and I should post my problem on Airgun Nations forum and that possibly the trigger maker would answer me. As of today he has not. After doing my own investigating  I found out that my rifle took their other trigger called the Nitro. I decided to order another trigger, this time the right one, but after being told that because they did not make the trigger themselves they could not be of any help to me I figured that they were a seller of most, if not all, the products they sell and did not manufacture anything themselves they would not be able to give me any help with anything I purchased from them so I ordered the correct trigger that I needed from Charliedtauna, who I was told was always very helpful. I was so disturbed by this transaction that I did not even try to send back the wrong trigger as I did not want any more aggravation so I will either give or sell the trigger to one of my friends that can use it on one of their rifles.
