Bad Turn Signal Connector

Both of my front blinkers are working intermittently. I have diagnosed the problem to be bad connections but I don't know what the part is. I can get them to work when I push on the wire connected to the plug that is part of the wiring harness. So I know the bulbs are good, the blinker is good, but the connection of the wires into the back of the plug is bad.

Anyone know if you can pull these apart or buy new ones. I went to Toyota and the service tech said he didn't know anything until I pay him to diagnose the problem or I can buy a whole new wire harness for $1500 and get the parts. But I am not going to pay them to diagnose a problem that I can show them the solution and defiantly not gonna buy a new harness.

 

Easy fix. I had to replace one of mine on the turn signal a couple years back. The wires just get brittle.

 

Thats it. Thanks
