Technic makes three different harnesses for the base system.

I believe the simplest one is just wires and connectors for the under-seats.
I believe I also saw speaker adapters on his site.

What you get with the 62dsp I have no idea , so I would be only guessing
but you might need a combination of those items. You might send him
and Email.

Ooh thank you. by any chance do you have his email. I've left a message on his profile yesterday or Friday, but I doubt he will answer it since there's plenty of recent unanswered questions and it says he hasn't been active for a few months.
