DSE Wiper install- wiring colors/position for plug? 67 Camaro

[boostin05blacksti]

Hi guys, bought this used but in new condition.. All original packing ect.. But with no instructions. Emailed DSE yesterday and they sent them over. For the plug on the motor is showing 5 wires on the instructions and my harness only has 4 supplied. Also they say in the instructions that the plug comes with the blanks already installed. Attached is a picture of the blanks which where already installed, and what wires I have.. Want to get this correct before I put 12v to it.. Thanks Steven
