MXDL with a Groove Driver

So, I got an MXDL host, and drilled out the sides of the part that holds the LED, to make room for a Groove Driver sideways (with one of jayrob's heatsinks in it). it fits and works great, but I don't know which end on the driver is for the diode and which for power, and which side is for positive and which is for negative. I'm guessing it's like the FlexDrive V4/V5, where the one that has a large flat piece is battery positive, adjacent to it is negative, and directly across from those are their diode counterparts.

show me a pic if possible. its been a while since i messed with them.

edit: im goin to sleep now so pm me and remind me to check the thread if you dont get any help. if im not mistaken theres a side with 2 round holes and the other side has one round and one square hole. the side with the square hole is the battery side but confirm it with someone else or show me a pic before hooking your diode up.

I soldered wires to it a while ago, but there's a good picture of the PCB in the assembly manual here: http://hacylon.case.edu/laser/lavadrive1/Assembly_Instructions.pdf

the side with the large square is the battery side and the side with the small square is the diode side.

And the squares are the positives, correct?

Is there a Mod who could please move this to the help section? Thank you.
