Trailer Wiring Harness Installation - 2008 Mercury Mariner- Video
Today on our 2008 Mercury Mariner we'll be installing the tow package wiring harness with four pole trailer connector from Draw-Tite, part number 118251. Now we'll be installing this in conjunction with the four terminal relays, part number TR38665. To being we'll go ahead and install our four pole harness. Underneath the vehicle here on the drivers side at the read bumper we'll go ahead and locate the factory plug here. Now we'll need to remove the covering from the plug so we'll go ahead and detach it from the body of the vehicle and unplug the harness. Now that we've exposed the plug we can take our new four pole and clip it into the plug here on our factory harness. more
