So far I have found
the power seat typically uses a 4-pin connector for the driver’s side 6-way power seat (forward/reverse, tilt, and lumbar). Here’s a breakdown based on discussions from Mustang forums:
- 4-Pin Connector:
- Black wire: Ground.
- Dark Green wire: Power for seat track motors (forward/reverse and tilt).
- White/Blue or Light Blue/White wire: Often tied to the lumbar or power circuit.
- Fourth wire (commonly a different color, e.g., green or yellow): Typically for the seat belt indicator light, which may not be used if retrofitting into an older model without this feature.
- Wiring Setup:
- Connect the black wire to ground.
- The dark green and white/blue wires usually need power from the vehicle’s 2-pin harness (if present) or a new power source (fused, typically 30A, from the fuse box).
- If retrofitting, you may need to run a jumper from the ground to the 4-pin connector’s ground and splice the power wires to the two motor-related pins (lower two pins if the ground is top left).
- The seat belt indicator wire can often be left unconnected if not needed.
- Fuse Location:
- The power seat fuse is typically in the under-dash fuse box (interior fuse panel). For a 2000 Mustang GT, check the fuse labeled for power seats (often 30A, but consult the owner’s manual or fuse box cover). If the seat isn’t working, a blown fuse is a common issue after incorrect wiring.
MY seats also have a 2 prong connector I don't know what it goes to and I haven't found info on. Either a seat warmer or Lumbar balloons?
I'm retrofitting a set of premium New Edge Leather seats in my '69, does anyone have a wiring diagram so I can build a harness? I only have the seat side plugs and not the chassis side.
