I am rebuilding a later model 4.2ABH. 1993

Checking through the seats operation, the cable harness includes additional connectors, in the door, and at the seat, which appear to be memory module connections.
I have already resolved some mirror issues related to the mirror memory function.

Would these connectors be present even if the car did not originally have memory seats?
Am I able to simply install the switches and control box, or is there more to the system?


Ps. This forum software really doesn't like iPad, does it?
