fault lamp. Lengths correspond with the style of
rear sill. However, the slim line female
connections at the end allow you to add an
extension if the length is too short.
Note: The male pin lamp plug will fit both
incandescent and LED lamps. Also, additional
information and options for rear sills can be
found on page 39.
Step Three:
Identify the harnesses needed for the front
marker lamps. The type of lamp and style will
determine your harness requirements.
Example of type: If using a single lamp on
each front corner, you will require a lamp that
is PC rated.
Front clearance harness: For this harness Grote
has provided the end user several options in both
power connections and lamp styles.
First determine the routing of the harness and the
length you will need from your power connection
to the lamp(s). Power connections offered in this
catalog are either ring terminal or slimline 0.180
male bullets that plug into provided drops on the
main harness. (Note: the ring terminals are
overmolded for protection).
For the front marker there are two lamp
connection options. The first option is a PL-10
plug that plugs directly into the lamp. The second
two options both utilize 0.180 slimline female
connections for various lamp pigtails.
Note: The flow through version accommodates
two lamps per corner, (P2 rating). Also, roadside
and curbside lengths are different to
accommodate offset nosebox receptacles.
Step Four:
As we move to the rear of the trailer, we identify
the harnesses required for the rear marker and
license lamps. Using the straight through rear sills
allows for direct connections into the system using
0.180 slim line male and female connections.
Rear marker harness: Four harness options
have been provided for this application. All
harnesses options are two feet in length and
connect to the provided drops on the rear sill.
The first three harnesses have lamp connections
that plug directly into the lamp. The fourth
harness provides the end user with the option for
a pigtail, with slim line 0.180 connections.
ABS fault lamp harness: Grote has offered two
different lengths for this harness based on rear
sill application, (center or offset).
The offered plug options are the PL-10 and the
slim line 0.180 female for pigtail application.
This harness is to be plugged into the drop from
the 7-way plug on the rear sill if the length on
the rear sill is not long enough to reach ABS
fault lamp.
Note: This harness may not be required if drop
from rear sill will reach lamp.
License lamp harness: Three harness
configurations offer accessibility for any lamp
style. The option with the slim line 0.180 females
will connect to any standard license lamp pigtail.
This harness is designed to plug into the straight
through rear sill, as are the other rear marker
lamp harnesses.
Rear identification harness, (3 lamp) For this
harness, Grote has provided numerous options
based on length and lamp design. The two
lengths shown are designed for trailers where the
identification lights are on the lower frame, (36”
dimension), and in the upper rail, (120”
dimension). The 36” length can also be used with
a jumper harness for upper rail application. Both
styles offered plug directly into the straight
through rear sill with slim line 0.180
terminations.
Three lamp options have been provided, and a
fourth option for pigtails has also been listed. The
lamp options are the Turtleback II, the Marker
lamp plug and the Thin-line LED.
