I can't tell you which RV wire goes where without seeing your setup, and it's worth getting right. Have an RV tech meter the wires to confirm positive and negative before connecting the NR740.
Since I can't confirm this 100% from here, please email us at info@rvfridgeguys.com or call 800-712-8822 with your model and serial number and we'll double-check it for you. You can also browse www.rvfridgeguys.com.
