So my neighbor found this at the junk yard and so what do I need to convert it to a flat 4 plug?


It's got a 7 plug on it

It's got a converter box on it, but a pears to have 5 wires going in, then there are 4 wires coming out to a plug that has 4 in and four out.

 

Looks like maybe i can splice into the four wires coming out of the converter box?

Just match the colors, white with white, yellow/yellow, green/green, black/brown.

 

i dont see any two color wires?

the plug that goes from the vehicle plug to the adapter plug into the adapter, its 5 wires and colors are as follows
white
red
green
black
yellow

and out of the adapter is 4 wires,
white
brown
yellow
green

then goes from the 4 plug to the 7 plug wiring that is only using the
yellow
green
white
brown
the orange, red, purple are just taped off to nothing. what are these three wires used for?

the 7 wires coming off the 7 plug are as followed.
red
orange
green
yellow
brown
white
purple
