Just to let people that know about my experience with this guy...
I bought the above item however it was the INCORRECT part. After speaking to the ebay seller he told me to send that one back in and he'll send the proper one. Couple days later, it arrived and I had an email letting me know I could contact him with any questions etc.
The block was a 12 pin block and 3 cables (2 red, 1 black). Simple instructions - keep the red cables at the top.
Apparently he doesn't usually do the cables with the 12 pin blocks so he's going to be working on getting a few blocks for future cables.
All in all as irishz4 stated above, this guy is one of the good ones. Very good communication, selling a very simple but very effective product - at a great price compared to others.
