New version Nand-X J2B1 QSB. Where's the 3.3v solder pad?

I'm right in the middle of soldering my QSB's on and noticed some discrepancies between the version of QSB that came with my Nand-X vs. the QSB on some of the tutorials.

My J2B1 QSB does not extend over to the R1 solder point as shown in this image:


Instead it's the shorter version (without version#) like this one:



My question is.
In the first image there's leads for the 3.3v and stby clk on the QSB going to the Coolrunner. Whereas the second image there is not.

How do I tie these two points to the Coolrunner with this type of QSB shown in image 2?

you just solder the wire that is supposed to go on the coolrunner qsb to the point shown in the coolrunner wires installation and the 3v3 to the contact on the nand-x qsb

There is two types of QSBs buddy Slim & Phat you have Phat by the sounds of it
Thanks,
I realize I have the Phat. This is where I'm confused. The tutorial for the Phat shows the longer QSB.
The QSB that came in my Nand-X kit is the other one.

you just solder the wire that is supposed to go on the coolrunner qsb to the point shown in the coolrunner wires installation and the 3v3 to the contact on the nand-x qsb
So just solder points A, C, and D to the Coolrunner, use the 3.3v solder pad on the Nandx QSB to the Coolrunner's 3.3 solder pad, and leave the stby clk out?

That's not the right QSB for coolrunner - these ones are designed for JTAG - you need to purchase the QSB for coolrunner separately......the ones that come with the NAND-X are JTAG - not RGH

In the first is j2b1 v2 in the second is the first version. The first version is sold in the nand-x package The second (in the first image) is sold separatly and you can buy from reseller.

they can still be used in the same way eccept you will need to do a direct wire install for the orange wire :). ive been using them as the coolrunner QSB's wasnt in stock with MT

Crap.
Okay. Makes sense now. That detail never became too clear in any of the tutorials.
Is there any way to solder direct-wire or shall I just put in another order for the RGH QSB?

Wow, you guys are posting replys faster than I can reply back...
Thanks for the help.

I noticed the resistor on the RGH Qsb. I assumed that was necessary. You're saying I can direct wire the stby clk wire over to that point and continue forward?
I have my box totally apart right now, I'd rather not have to place another order but I will if necessary. Want to do this first one right!
