OK in one of the pictures in the first post of this thread I mentioned I had to go with a 90 Degree USB Mini-B type cable to make my installation work at the bottom of the center console storage bin. I finally have some solid information I can share on this topic with some pictures to illustrate the differences.
So first lets be clear the receptacles we are talking about are GM factory parts that all seems to have the same type of USB Mini-B connector input.
First I will start out with my first attempt, a straight universal USB Mini-B cord:
So with this one plugged in I just barely did not have enough clearance as the cord hit the floor of the trans tunnel. The receptacle would not sit all the way in the hole I had cut out and lock in. So had to find another solution.
Looking around I found a GM cord (19303328 about $20.00) that had the correct Delphi Automotive connector to go into my GM receptacle. I thought great a solid connection and a factory solution!! Unfortunately it stuck out even further than the straight universal solution I first tried.
But trying the GM/Delphi cord was helpful in this regard. If you are planning to mount a receptacle in any other location and have a bit more depth this maybe the solution for you. Not only do you get a factory positive locking USB Mini-B plug but the total length of it is around 38 inches. More than enough to reach to the glove box or front cubby. It may even be enough to get to the center console storage bin if the depth was not an issue. So this was a good find:
So then I looked for Universal 90 degree USB Mini-B plugs in the market. Not that easy to find and I will tell you why. There does not seem to be a generally acceptable name for the configuration of plug we need. One Manufacture calls it an Up Angle 90 Degree USB Mini-B while another one calls it a Down Angle. And the difference is quite important if you are using any of the GM receptacles with a AUX in plug that can be in the way. If you are just going into a single USB receptacle I guess it wont be all the important as far as up or down angle.
So first one was the Tripp-Lite model UR030-006-DNB - about $6.00 From various online retailers. (UPDATE: Looks like these are discontinued by Tripp-Lite DigiKey has about 170 of them left at a good price Link To DigiKey
) It cut down installation depth quite considerably with the added benefit that I did not have to modify the receptacle at all because of the longer neck of the plug cleared the receptacle plug walls.
So just wanting to cover all the bases I got another cord off Ebay that would work well also. Problem is in this case it worked too well. It was the smallest depth of them all but it required modification of the receptacle (cutting off the factory plug locking tab) and since the AUX IN plug was now sticking further out than the USB plug it sort of defeated the purpose of it. But if you need the smallest depth possible for your install this is the cord for it. Search Ebay for "Up angle 90 degree Mini usb B 1.5" There is only 1 seller currently and it ships from China, Very fast shipping, it is amazing China shipments are coming faster than domestic these days. About $6.00 also. Length is 6 foot so plenty to work with. Seller was "just_for_survive" on Ebay
So in the end I went with the Tripp-Lite product. Final installation has some friction tape around the plug so it wedged into the receptacle to hopefully stay in place over the years. If it ever falls out I will rig up some tie wraps to lock it in place. But for now it seems pretty tight in there.
Please post up any more info if you come across something good in your search!
