Painless Performance Products 10106, Installation Instructions Manual

Page: 11 / 45

6.1.3 Install the firewall grommet (early models only). Route engine and headlight
group wires through the grommet and position the harness groups in the areas
decided upon in Sections 5.3 and 5.4.
6.1.4 Route dash group (ACCESSORY SECTION B+, ACCESSORY SECTION SWITCHES,
HEADLIGHT SECTION B, INSTRUMENT PANEL SECTION, and RADIO SECTION)
upward to rear of dash and temporarily tie in place.
6.1.5 Position the TAIL SECTION on the floor pan area.
6.2 Harness Attachment
Note: Harness routing and shaping is and should be a time-consuming task.
Taking your time will enhance the beauty of your installation. Please be
patient and TAKE YOUR TIME!
6.2.1 Permanently mount the fuse block.
6.2.2
Mold harness groups to the contour of floor pan, firewall, fender panels, and any
other area where wires or harness groups are routed. Remember to route the
harness away from sharp edges, exhaust pipes, hood, trunk, and door hinges,
etc.
6.2.3 Attach harness groups to your Jeep with clips or ties starting at the fuse block
and working toward the rubber grommet (early models) for the front groups and
along the floor pan for the rear group. The dash wires should be routed out of
the way of any under-dash obstacles, such as the cowl vent, air conditioning,
radio, etc.
Note: Do not tighten tie wraps and mounting devices at this time. Make all
harness attachments LOOSELY.
6.2.4 When used every 1-½” or so on the visible areas of the harness, the plastic wire
ties make a very secure assembly. A tie installed in other areas every 6” or so
will hold the wires in place nicely. Remember to take your time!
6.3 Grounding the Jeep
A perfectly and beautifully wired Jeep will nonetheless have bugs and problems if
everything is not properly grounded. Do not go to the careful effort of installing a quality
wire harness only to neglect proper grounding.
Note: The Painless wire harness kit includes no ground wire except the black
wire from the two headlamp connectors. You must supply ground wire
(14-16 gauge) for all circuits. If ground wire is needed, we suggest
using the excess wire cut off from the harness.
6.3.1 Connect a Ground Strap or Cable (even a 10-gauge wire is too small) from the
Negative Battery terminal to the Jeep chassis (frame).
6.3.2 Connect a Ground Strap from the engine to the chassis. DO NOT RELY UPON
THE MOTOR MOUNTS TO MAKE THIS CONNECTION.
6.3.3 Connect a Ground Strap from the engine to the body.
6.3.4 If you have a fiberglass body you should install a terminal block (Painless Part
#40026) to ground all of your gauges and accessories. Ground the terminal
block and everything connected to it will be grounded.
