You will need to use the wire and plug from the OEM power supply.

You will need to cut the wire from the OEM power supply. First identify which wire is positive and which is negative.  Mark them with a piece of tape so you can still identify them after you cut the wire. Cut the wire off the origianl power supply about 1 foot from the actual transformer.  Strip the wire about two inches and wrap the wire around each terminal for each lead.  Red is positive, black is negative.  Set the amperage to maximum and adjust the output voltage to 14.5-15V for 1/32 cars or 18V for 1/24 cars.
