Would you daily drive an early A?

I will look into the retractable lock switch since I don't see a seat computer.

Note the shoulder belt locking control was seperate in it's own module up to around 2000 & then slid into one of the functions of the main computer after that.....you'll need the parts of the two harnesses if pulling one of these modules.

A recent Ebay item for the seat belt control module PO4671300AB:

A wiring diagram for the shoulder belt control incorporating the locking switch:

Since you need some juice for the power seat as well it's necessary to consider an underhood fuse box (along with handling lights, HEI, etc.) to avoid pushing your weak Dart harness, box, bulkhead connector, etc into outer space.

The double throw toggle switch interrupts power to the shoulder harness solenoid to accomplish the goal of locking up the harness and keeping you away from the steering wheel on impact.

My daughter's 65 Dart came out of a wrecking yard; it had some frontend damage, windshield smashed just above the steering wheel, and bent twisted steering wheel.....we assume that driver didn't make out so good even though the damage to the car was minimal.
