After having the car stripped to bare metal and repainted, factory installed rust repaired, etc., I’m in the process of reinstalling my interior. I have a parts car, giving me the ability to put an electric tilt base seat on the passenger side, in addition to the original on the driver’s side. My plan is to tap into the existing driver’s seat power line for the add-on passenger base motor. Question: Will each designated seat switch operate their own seat respectively, or will either switch operate both seats? Am I courting some unforeseen problem, or is this going to be an easy and desirable upgrade.? Thank you.

John,
I made this modification to two of my former XJ6s and my current XJ12 with parts from my three XJ6 parts cars. I wired the new front passenger seat motor using the wires for the driver’s seat motor so that each switch only controlled the seat it was installed on.
Adding an extra load to the same circuit may blow a fuse when both motors are operated simultaneously, John - a minor matter. Don’t up the fuse though…
You have power and ground. You use power to give power to the passenger seat. You use ground on the other lead. You may not want to run them simultaneously, simple enough.
Frank,
I considered the electrical load on that fuse when I added the passenger seat lift motors to my cars. 90 % of the time I am the only one in the car and I rarely use the drivers seat lift motor. I adjusted the front passenger seat lift motor for where my wife likes her seat when she is riding in my cars. I figured that the chances of a driver and front passenger adjusting their seat lift motors simultaneously would rarely if ever happen, so I didn’t do anything to accommodate the load. I figured that if that ever happened and I had a blown fuse then I would simply replace it. I haven’t had a single lift motor fuse blow in the roughly 15 years that I did the first of three cars.
I’m more concerned about wiring loads than fuses; sort of general warning against upgrading fuses when extra loads are added to a circuit and blowing fuses…
The fuses are there to protect the wiring, David - and are dimensioned according to respective wire gauges. With high enough current the wires will burn - unless the fuse blows…
