Northstar Trailers SPORTSTAR II - 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 out from both the back
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 (C) 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 the bolts.
d. Attach side braces (10) to the tongue of trailer using 3 ½” threaded pin-bolt
(D) and a large nut (C).
e. Attach the side-braces to the frame using 1” bolts (J), flat-washers (I), small
locknuts (T) and small lock-washers (H). (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. Then insert cotter-pins, 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
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
the 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.
