Standard Cable Installation:
Vehicles with the standard (full length) ground cable will bolt to the engine block in place of the
original ground cable. With this configuration you will need to install the supplied 21” #6 black
ground cable (item # 32)
Use the M6x1 ground stud on top of the frame rail
directly under the A/C charge port. This is about
even with the front edge of the coolant reservoir.
Attach the end with the smaller hole. Attach the
other end to the front of the cylinder head using the
M10x1.5x20mm bolt and star washer supplied (item
# 29).
Lightweight Cable Installation:
Vehicles with the light-weight cable configuration will
require a 3/8”x16x1 bolt (part #30) welded in the rear
and front sections. The rear ground bolt should be
located on the bottom of the frame about 5 inches back
from the rear of the aluminum sub frame and as far to
the outside of the frame as possible while remaining on
the flat surface. The head of the bolt should be sanded
flat before welding and the paint must be sanded off of
the frame in area to be welded. Disconnect the PCM
before welding on chassis. Weld the bolt continuously
around so moisture does not get between the bolt and
the frame.
The front ground bolt should be located under the coolant reservoir on top of the frame surface about
1 inch forward of the strut tower bracket. It should be prepped as explained for the rear ground bolt.
TIG welding is recommended to minimize chance for fire or damage to surrounding parts. Use the
12 inch ground wire to go from your front ground stud to the front of the head. Install a star washer
and 3/8”x16 nut on the ground stud, use the supplied M10x1.5x20mm bolt and star washer (item #
29) to secure to the front of the cylinder head. Use a star washer and a 3/8”x16 nut to secure ground
to frame on the rear.
