From the 49'er side:
The lead closest to Q4 goes to pin 24 on J1 of the DDS board - that is the T/R connection. ?In the picture you posted, that is the right most terminal on the 49'er board.
Decide if you are going to use the low voltage output from the DDS-VFO (use J2) or the high output (use J3).
The middle lead goes to ground at whichever you choose based upon that decision.
The remaining lead goes to the corresponding + terminal at J2 or J3.
The photo shows pin connections on the DDS board which are not present in the current release, which is why it might be confusing.
Hope this helps.
