E-Sys Dongle DIY (done a little different)

So I ordered my OBDII adapter off ebay just svache's post (took 4 weeks to come from Hong Kong, 1$ for the adapter, $2.31 for postage.



When it got here I thought instead of just building the cable like it said, how Rube Goldberg could I make this thing. Maybe instead of just wiring an ethernet cable to the adapter, what if I cut it up and buried an ethernet jack into the adapter. That way I could just leave the adapter in my glove box and use any standard Ethernet cable with it of any size that was convenient at the time. I went and grabbed an adapter out of my bag, and it looked like it might be close enough to fit



Inside looked like some stuff would have to be removed and the tabs on the Ethernet jack removed as well



Well might as well try cutting it up - it only took 4 weeks for it to get here right? Maybe I should have bought 2....
I took my Dremel and cut out all the offending plastic - here's a "before and after"



And took the Dremel to the Ethernet jack as well, then filed everything "smooth" with some 150 grit sand paper



Dry fitting - That might just work



Cabled it up per the diagram (note - I didn't take a picture with the resistor soldered on b/c I haven't bought it yet)
These little jacks are super easy to use, just thread the cable through the middle and over the slot of the pin you're interested in, then use the plastic tool that comes with it to force the cable into the slot



Clipped off the extra cables and put the Ethernet cover on - internally "finished"



I had done our Christmas card address labels yesterday, so I still had a sheet of labels in the printer - figured I should put a roundel on it just in case I forgot what it was for



Enjoy!

What a handy man (or a woman) !

It's perfect for the guy i read here who had no laptop and had to run the Ethernet cable all the way from his garage into his house to a desktop - coding his F30 -

Thanks guys-took delivery of my car on Tuesday and started coding it that night

The adapter worked like a champ-exactly what I wanted. Second day I used a longer cable with it so I could sit in at the kitchen table and code
