You might want to give Tony Williams a call and tell him about your need for an adapter such as the Jadapter but you cannot wait for it. A few months ago, there was a promotional code to get $160.00 off the $399.00 list price for the J stub. I know it's true because I bought one for $239.00 on the 30th of August this year. I have a Tesla HPWC and really wanted to use it with my Volt and my Victory Empulse motorcycle. The adapter works great on all of the vehicles I have tried it on and is nicely manufactured.
I wish I still had the code, but I put it on the order paperwork and didn't write it down. It is not shown on my receipt, just the $160.00 adjustment. They are pretty good people and might still have this deal or could cut you a deal just to be nice. It's worth asking anyway.
BTW--if I find the code I will edit and post it here
Found it! The promo code is (was) --- JDapter239---- Give it a try if you are interested.
