Have you ever jacked up your car before? I can't get to the D plug from above (I have no idea how some people say they can), so I open the hood, close the doors so the car starts to go into it's sleep cycle...while it's doing that, I jack up my car (I use a jack and jackstands), remove the underside tray and remove the afr wire (blue wire - not on the jb1)...by the time I'm done with that (I take my time), the car should be asleep (it takes about 10 mins...this just helps you avoid fault codes after you remove the jb4...first time I did not do this and I had a christmas tree on my dashboard and had to turn the car on/off twice and drive down the block to clear the codes)...so after those 10 minutes to let the car go to sleep, you can remove the D clip on the bottom, plug the stock one back in (this is the clip that can cause the most headache), then remove the 2 top clips and take everything else out...after this you would take out the obd2 plug and hide it up with the rest of the wiring...I would say including jacking up the car and waiting for the car to go to sleep, maybe 15 minutes now that I have a hang of it, probably closer to 30 when I first started.
