Step By Step Instructions to Wire Your Vehicle

• Disconnect the battery in your vehicle before starting 
• Read the installation instructions and look at all diagrams before proceeding 
• Setup a plan before you get started 
• Check your kit to make sure everything is included 
• Lay the harness out on the floor 
• Plan the path to which way your wires will be routed 
• Only remove the ties holding the bundles together 
• Leave all labels on the wiring harness until you have completely installed your kit 
• The fuse block must be mounted near the steering column under the dash (the wires may be too short if you mount the fuse panel in another location). 
• Mount all electrical accessories and switches where they will be on the vehicle (so that the wires are trimmed to the correct length). 
• You may need some optional accessories and wiring components (see the listing of optional accessories at the end of this instruction sheet.

Grounding 

Grounding Symbol

Ground wires are not included in this kit. Fiberglass body cars cannot use the body as a ground and must run individual ground wires from all components to the frame or engine. In most situations the ground wires must be added to connect the case of each component to the engine or chassis. 

Heavy gauge battery cables and grounding straps must be used between the engine/body/frame and the negative battery terminal. The best place to attach the ground strap to the engine is on a starter motor bolt to make sure the starter gets adequate voltage. 

All ground connections must be metal to metal connections that are free of dirt, rust, and paint. 

Testing 

Test for any problems that may occur upon installation completion with a 10 amp or small battery charger to ensure safety. 

Proceed with the installation only after you have read and understand all of the above steps and guidelines. 

Mounting Fuse Panel 

The Fuse Panel must be mounted near the steering column. When mounting the fuse panel, use the two plastic spacers between the fuse panel and firewall or other mounting surface (this allows room for the wires that run behind the fuse panel). Use the ¾” grommet supplied with the kit to protect the wires where they pass through the firewall. Use similar grommets (available separately) for any other wires that pass through any other panels in the vehicle. 

Wiring Groups 

The wires that are attached to the fuse panel are organized into groups based on where the wires are connected to the vehicle. Each of these wire groups are shown below along with drawings that show how to make the connections to your vehicle. In some cases there may be different drawings for each type of vehicle (i.e. GM, Ford, and Mopar). You may also need to reference a service manual for electrical drawings for other vehicles since this harness can be used with almost any vehicle that has the engine located in the front and the fuse panel mounted under the dash near the steering column.
