Reposition the dongle
So, loosing that little shelf for the dongle was a bit annoying right? Here is what I did. First, get yourself an ultra-flat OBD2 extension cable, such as this one www.ebay.com.au/itm/181765630282. You also need two RJ-45 connectors, an RJ-45 connection block and a crimp tool for the connectors.
Now that male plug is still not flat enough to fit under the shelf, so carefully shave off it’s top like this. Also, cut the cable 10 cm from the female end and crimp RJ-45 connectors on both ends, fitting the colors of the strands in the same sequence in both RJ-45 connectors. Be wise and check if the dongle still works with the two ends connected through the block before continuing.
Next, widen the hole so a standard RJ-45 connector can be pushed through.
Push a piece of stiff electical wire through to either side of the console. It works best if you pry the plastic of the console a bit away from the carpet.
Use the electrical wire to pull the long part of the extension cable (with the male connector) through from the top, RJ-45 end first. Because of the locking clip of the RJ-45, this will be a once-only operation, unless you are prepared to widen that hole substantially more. Or simply cut the wire at the RJ-45 end when you need to remove it. Connect the two parts using the connection block. Finally, push the dongle into the female end of the now rejoined extension cable.
Connect the male end to the car’s SAE 1962 connector and carefully wrap the cable so it won’t push up the shelf. Check again if everything works.
Reseat the shelf.
I tucked the cable under the console. I like this setup, as I can switch it off. Of course you can put it elsewhere or even hide it entirely if you don’t care about switching it off (you should care!).
PS: Later on (no picture) I moved the dongle a lot more to the aft side. That got it out of the way of careless feet, and because of the shape of the floor it is pushed flush against the console instead of sticking out like you can see in the picture. Finally, it makes the LED’s far easier to see. Much better.
