All of these use the same pins as factory so you do not need to modify your factory harness other than moving some pins around. The connector the factory harness connects to is a locking/latching connector of OEM quality to reduce any reliability risk.

Then you can hook up an AUX 12V to the toolless connector if you want, likely to the cigarette lighter, Then your data logger(s) will plug into the unit via the toolless connector provided.

All the factory signals pass through the buffer and are retransmitted out the data logger ports. There is a switch to allow the car's wakeup signal to turn the power on/off to your loggers to prevent battery drain.

Once I get real boards I'll hook it up in my car and make a user manual with pictures.
Thank you for the detailed explanation.
Mine is a track only car with DCT, and I'm using CAN signals from junction box for my logger. If possible, can you upload photos of the actual installation? I think photos of the actual installation will help me figure out how to use this in my car.

Also, I thought it would be good if a part related to firmware update was included in the module to avoid any software problems.
