Help with two way system for car racing

Hopefully someone can help or point in the right direction. We have a cheapo Midland two way radio system in our race car and would like to wire onboard MXT400 system. However, car’s push talk harness uses 2.5mm mic plug but we see that mxt400 shoulder mic has a house phone plug. Can the two be wired somehow?

Probably. Is the car harness TRS or TRRS? I’d guess TRS.

Anyway, if you can get schematics it would be simple to figure out. Otherwise it can be reverse-engineered.
