I am wondering if anybody knows of a source besides the dealer for the electrical connectors found on the ends of a 1991 W124 M103 wiring harness.

I am interested in the two pole connectors for the coolant level (at overflow tank) and coolant temperature sender units. These appear to be clip on connectors housing the two female electrical connectors. I hope that description was clear enough. Most of the plastic connectors are brittle and have fallen apart when touched. Thanks in advance for any help.
