After you've crimped the sockets onto the wires and inserted them into the 7-pin MICRO relay box, the yellow plastic clips should hold the sockets in place when the relay is fitted. The latches are weak and don't hold the sockets in place. After installing all the wires to the base of the box (4 or 5 wires per relay x 7) it is not possible to use the small eyelets provided for mounting. You'll have to make your own mounting system or, like I did, mount it under the dash with zip ties. After looking at the reviews of others here, it looks like they haven't actually used the relay box. So I repeat - it's flimsy and doesn't hold the wires in place. When you connect a relay it tends to push the sockets out the back of the box. This makes it unusable.
