Northstar Trailers MULTISTAR - Manual (Page 9)

STEP 4: ATTACH TONGUE TO FRAME
Remember: the trailer is still upside-down, so all components must be installed upside-down.
a. *Make sure that the tongue’s wiring harness extends through both the backside and
the front of the tongue.
b. Align the tongue’s (2) eyeholes with the eyeholes on the frame.
c. Use the 3 5/8” threaded pin-bolts (E) and large nuts (H) to fasten the tongue to the
frame.
Note: do not fully tighten the bolts or install the cotter-pins until the side-braces are
installed. Be careful not to pinch or cut the tongue’s wiring harness when inserting bolts.
d. Attach the side-braces (11) to the tongue of trailer using 3 ½” threaded pin-bolt
(D) and a large nut (H).
e. Attach the side-braces to the frame using 1” bolts (L), and large locknuts (C).
(NORTHSTAR will read upside down).
f. Once the side-braces are attached, tighten the 3 5/8” bolts from step “c” as tight as
a manual wrench will allow, insert cotter-pins (M), and secure the cotter-pins by
bending at least one leg to 90 degrees.
g. Check and make sure that all other bolts are tight.
h. Securely tighten the bolts that connect the trailer’s coupler/hitch to the tongue.
(These bolts are loose. You must tighten them).
*Note: In rare cases the tongue’s wiring harness may fall inside the tongue after shipping and
unpacking, and you may need to fish the wires and pull them out of the tongue.
TIGHTEN AND SECURE ALL BOLTS! After the tongue and the side-braces are in their
proper positions, make sure to securely tighten all bolts, and make sure that all cotter-pins
are installed, and that at least one leg of the cotter-pin is bent to 90 degrees.
STEP 5: FINAL WIRING ADJUSTMENT
a. Ensure that the tow-vehicle connector (trailer plug) and wires that extend from the
hitch have sufficient slack to connect to the vehicle’s receptor plug.
b. Plug together the tongue’s wiring harness with the trailer frame’s wiring harness.
c. Tuck any excess wire and the main wiring connector into the base of the tongue.
ROTATE THE TRAILER TO AN UPRIGHT POSITION.
Position the
trailer so the tires are on the ground. More than one person is required to rotate the
trailer; DO NOT ATTEMPT TO ROTATE THE TRAILER TO THIS POSTION ALONE.
