Convertibles with 3 point seat belt conversion?

I just picked up some Chrysler Sebring seats with the shoulder harness. Working on mounting brackets now.
Also got the rear seat from the same car, they are the same width as the seat in my '64 Valiant. I'll adapt them to the stock frame.
I'll start a thread with pics as I get further along.

Sebring seats with built in shoulder harness. Perfect!

I started working on mounting these seats, but noticed right off that the while driver seatbelt works fine, the passenger belt was locked, it would retract, but not pull out.
What I thought was a seat belt buzzer/warning turns out to be a solonoid connected to the airbag controller module. Apparently it's supposed to lock if the airbag is deployed.
Applied 12V to the wires and it released the belt. The belt will lock tight if pulled quickly, like your torso going forward, so still fully functional.
I'll wire it to an accessory hot lead with it's own fuse. If that fails I'll break into the housing and manually disengage the solonoid.
