How to Make 7-Way Adapter for Scooter Lift to Plug Into 7-Way on Honda Ridgeline  

Updated 08/08/2025 | Published 01/08/2016



Question:

I am using a mobility scooter lift that fits in the trailer hitch of my 2011 Honda Ridgeline. I have a 2 wire flat plug on the scooter lift that I need to have full time power. If I use the PK 12716 adapter, which will be the constant hot and constant ground? I know that two of the 4 wires will be for the turn signals, dont want to use them at all, if I can help it. Thanks,

Expert Reply:

The adapter part # PK12716 that you referenced only carries turn signal circuits so while I have a solution that would work, this would not be it.

Instead you would want to wire the scooter lift power wires to a 7-way like part # PK12706. The ground circuit will be the pin in the 5:00 position and the 12 volt power would be in the 11:00 position.

Same here. But the wheelchair lift has a a 2 red & 2 black How do I know which is which? The Harmer manual only talks about using an external harness, which is silly because I have a four pin and seven pin on my car. I understand that I need to connect the tail lights & aux power. How are you supposed to know which is what? I live in an area that has very little to take it to someone

@Jennifer You'd have to check with Harmer to get that info as we don't have a way to determine which black wire and which red wire does what.

Can the 12V Wire on 7-Way Power a Scooter Lift

The answer to this will depend on your scooter lift. The 12V wire can be used to power your scooter lift but it will be limited by the fuse in your vehicle. From what I was able to find, this is a 30 Amp fuse in the 2019 Honda Pilot. I would double…
