Guys, I need your help.

I posted a year ago about the need to "T" into the warning lights on my TC40D to connect a 7 pin connector so I can run a set of tail lights and flashers on my hay wagaon. I wanted to avoid using splice connectors into the existing wires.

Well I'm back again but this time with the TC40DA. The wiring harness appears to be a little different. The old D tractor had a triangular shapped connector near the tail light/flasher assembly. The new DA has a traditional square shape but still uses only three wires.

I'm trying to find a "T" that would go into the existing harness.

Any suggestions?
