Yep, take the connector back out, ensure that clip/latch is fully over (from memory I think the latch part was all the way to the front of the car) then press the connector firmly down and then pull the latch all the way over until it clicks into place. Its like a set of gears that pull the connector down and to get it to properly seat the latch has to be all the way in the open position, then the connector in, then pull the latch right back over the other way. If you seat the connector and the latch is say half way, then it clips into position only half the way down making it intermittent.
