Unfortunately, there is no wiring harness that's currently available in written format for the Rascal AutoGo 550 as the Rascal scooter company has gone out of business.
What I recommend that you do is send us a picture of the battery box in its entirety, specifically the inside. What I really want to see is where those blue and brown wires connect to within the battery box. Are they leading to a circuit of some kind?
If you can get that together, we have a number that you can text it to. Now I can't list that number online because of all the bots and such that'll text us non-stop, so give us a call at 1-877-775-4381. Customer Service will give you a number to text that picture to so we can take a better look for you.
The below is my best educated guess on what we're looking at. But again, I would like to see a picture before we make any final recommendations.
The red wire will certainly be the main positive, and the black wire the main negative. Question comes down to the blue and brown wire. I believe the blue wire will be the charger circuit positive, and the brown wire will be the charger circuit negative. So our best educated guess is the red wire will be connected to the positive terminal of battery A, and the brown wire connected to the negative terminal of battery A. The blue wire connected to the positive of battery B, and the black connected to the negative of battery B.
