    If an ALP setup was purchased a few years ago (2-4 years), and I want to add a TX sensor, can I simply detach the existing RX head from the connector and attach the TX? Or, are the connectors different? I ask only to save some time and money if the installer doesn't have to remove the entire cable through the firewall that's attached to F2 on the CPU hidden under the dash. I'm going to replace the center heads on 2 of my ALP systems with TX sensors in the next 3 weeks. .

    Pretty sure there are old style connectors and new style connectors, if your system really is 4 years old I'm guessing there's going to be connector incompatibility.

    I sent an email to Alex at KMPH to see if he can look up if the cables are compatible. If not, it's not a big deal, it just saves the installer time and me money.

    There are two types of connectors. The older style is a DIN style connector, new style has a twist lock type of connector.

    When you change over the center head to a TX head, you'll need to also add the GPS module if you have a HW2 control box.

    If you have an original HW1 control box, you'll also need an R/G 2 adaptor along with the GPS module for it to work correctly.

    Can you post a picture of the connector that joins to your center head? Should be in the engine bay or grille area....

    I just did the install yesterday. There didn’seem to be any differences in the cords between the RX and TX.

    Of course as mentioned above if it’s an older set up vs newer model. I wouldn’t know.

    Just look on the bottom of your CPU. It needs to say "HW2" for compatibility with the TX sensor. "HW1" has the DIN style connectors. My system is nealy 4 years old and it's HW2 so you might be good

    Thanks for all the info. guys! The new system won't be an issue as everything will be brand new. I'll check the CPU on the other system tomorrow morning. Wife has the car. She works nights.

    Important: The TX Head MUST be plugged into F2 on the control box for it to function. One must have the GPS sensor for compete proper functioning.

    This is not entirely correct. Only really old HW1 systems had DIN connectors (I think units purchased in early 2013). My original ALP CPU that I bought about 4 years ago (Jun 2014) was HW1 with twist lock connectors, and I think HW2 came out around July 2014. Also, HW1 can use the TX, they just need to find a used RG2 module for the GPS since ALP no longer sells them. Although it is much easier to just upgrade the CPU to HW2.

    Well I was able to email Alex the serial number for the older system. He confirmed the older system was sold in Oct 2014 and it listed as a 2.0 from AL. He said it's fully compatible with the GPS plug-in on the G Port of the CPU. Order is being finalized for tomorrow. More goodies on the way!!!
