Topic: 1951 Mercury Convertible V8 Power Top Switch Info


toddah    -- 01-28-2026 @ 9:06 AM
  I an a electrical tech at a custom restoration shop. I have a 1951 Mercury V8 convert. I am installing completely new wiring in the car and I am building a new harness for the Hydraulic windows/seat system.
I have the Classic car wiring diagram but there are alot of details missing and I am hoping some of you gurus can lend me a hand with some info.
As I received the car, over the course of time the wiring is trashed and disconnected .
On the attached picture I have marked the two terminals that had wire ends attached but cut off. I have searched high and low fore a schematic but no luck.
The classic wiring diagram shows two blue conductors and a white with stripe attached to the top switch but has no designators as to what terminals each wire connects to.
Can anybody guide me in my adventure?
Attached is the classic diagram of the top switch

  From looking at the drawing in the Overhaul Manual, the terminal on the side (circled in red) has a wire from the circuit breaker and the other terminal goes to the center terminal of the solenoid on the hydraulic pump.

My scanner is down at the moment, but if this doesn't help you, send me a PM and I will scan it for you.
