Choosing the Right Wiring Harness

The first step in choosing a harness is determining how many circuits you need.  A circuit is a wire that has been designated for a specific purpose. The number of circuits needed is equal to the number of electrical components. Typically, a harness has between 8 and 12 circuits. You can, however purchase them with as many as 24 circuits. The more accessories in your vehicle, the more circuits you need.

Regardless of the number of circuits you need in your wiring harness, you should buy a harness that is expandable. This allows you to add circuits in the future.  Expandable harnesses use a heavier gauge wire and are made to accommodate a higher amperage. They also tend of perform better than regular harnesses in extreme circumstances.

    I have a 1978 GMC C15 step side truck that I am starting to build. I plan on using a 1986 Suburban with a 5.7 TBI, 700R4 as a donor for the drivetrain. I also plan on using the PW, PDL doors, cruise, delay wipe and tilt column from the Suburban. Also adding electric fuel pump and electric cooling fans.

    Is their a particular off-the-shelf kit for this, or is it something that would need to be made for this particular build?

    Thank You
