Gecko Circuit Board Sensors
To help identify which sensor you need look on the back cover or the right side of the main control box. You will find the Model & Options code.
Note what call letters the code starts with. For example SC-CF-P121-B1-01-LS-H4.0-AMP-XXX would be considered a S-Class control box.
Another example would be MSPA-MP-P122-P212-P312-O1-CP1-NE-L1-HLG-FB1-RTC-LS-JJM-MA3, this is a M-Class "MP". The final example shows that it is also an M-Class but has a possibility of the #1, #2 or #4 following the MSPA in this case the #1 (MSPA-1-P122-P222-B2-O1-FB-LS-H5.5-JJM-RL-AL).
