7.1.2  Attach harness groups to your vehicle with clips or ties (provided with this kit) 

starting at the fuse block and working your way out to the front and rear groups. 

The dash wires should be routed out of the way of any under dash obstacles, 
such air conditioning, radio, etc.  

 

7.1.3  When used every 1-1/2” or so on the visible areas of the harness, the plastic 

wire ties make a very attractive assembly. A tie wrap in other areas every 6” or 

so will hold the wires nicely. Convoluted loom also makes for an attractive 
assembly. 

 

CAUTION: 

DISCONNECT THE POWER FROM YOUR VEHICLE BY REMOVING THE 

NEGATIVE BATTERY CABLE FROM THE BATTERY. 

 

Note:   Make no wire connections or permanent mounting of any kind at this 

time!!!

 

 

7.2 

TERMINAL INSTALLATION AND MAKING CONNECTIONS 

 

Note:  In the following steps you will be making circuit connections. Before 

you start, you should carefully read Section 8 as appropriate, and 

continually refer to Section 10, DOUBLE-CHECKING your routing and 

length calculations before cutting any wires and making connections. 

Giving special attention to all switches.

 

 

 

 
7.2.1

 

Have all needed tools and connectors handy. 

7.2.2

 

Select the correct size for the wire and stud application. 

7.2.3

 

Determine the correct wire length and cut the wire. Remember to always allow 
enough slack in the harness and wires at places where movement could possibly 

occur, such as automobile body to frame, frame to engine, ect. Double-check 
your calculations.
 

7.2.4

 

Strip insulation away from wire. Strip only enough nessessory for the type of 

terminal lug you are using. 

7.2.5

 

Crimp the terminal onto the wire.  

 

Note:   Make sure the terminal is crimped with the proper crimping tool. An 

improper crimp will NOT make a good conection.  

 

CAUTION:  

DO NOT OVER CRIMP 

 
7.2.6

 

Connecting the harness throughout the groups is a redundant process. Make 

sure that each wire is first properly routed and then attach. DO NOT ATTACH 
FIRST THEN ROUTE AFTERWARD. 

7.2.7

 

When all wires are attached, tighten the mounts and ties to secure the harness 

permanently. 

 

7.3       GROUNDING THE AUTOMOBILE 
 

A perfectly and beautifully wired automobile will neverless have bugs and problems if       

             

everything is not properly grounded. Do not go to the careful effort of installing a quality    

             

harness only to neglect proper grounding. 

 

7.3.1

 

Connect a Ground strap or Cable (even a 10-gauge is too small) from the 

Negitive Battery terminal to the vehicle chassis (frame). 

7.3.2

 

Connect a Ground Strap from the Engine to the Chassis. DO NOT RELY UPON   

 

 

          THE MOTOR MOUNTS TO MAKE THIS CONNECTION. 

7.3.3

 

Connect a Ground Strap from the Engine to the Body.

7.3.4

 

If you have a fiberglass body you should install a terminal black to ground all
