Speedo help

It snap on connedtor is white and fairly easy to see. Lots of stuff in there should have been white. Anyway.. To get a couple of fingers on that connector and try to attach the cable aint gonna work. Here's why...
The end of the cable is floating in a large diameter cavity of that connector. It wont stay centered when you are moving the connector. Get a hand around the black sheathe behind the connector and steer it toward the instrument. That keeps the cable centered in the connector much better.
