I'm doing the Cutebee Vintage Coffee House. I've done 6 book nooks so far and all of the came prewired. this one has me attaching the wires. I assume I'm supposed to test them onto the battery pack wires where they are exposed?. 2 on the black and 2 on the red. The directions are badly translated or I'm just not getting it. LOL
Any help would be appreciated. Thanks!
