One important aspect of every classic truck, whether it's your
daily-driver or an occasionally driven show truck, is the wiring and electrical
system. It seems that every truck we see needs some type of electrical work to
repair damage, either from old age, previous owner's attempts at stereo
installation, or additional electronic components. Either way, it can become a
nightmare trying to patch up the factory wiring to correct any past problems.
Fortunately, classic vehicle owners and restorers now have the option of
replacing their original wiring with exact reproduction harnesses from a number
of aftermarket suppliers.
We chose M&H Electric Fabricators in Santa
Fe Springs, California, to supply us with a complete wiring harness setup for
our Project '72. M&H manufactures a vast array of exact reproduction wiring
harnesses, along with battery cables, spark plug wires, and switches for the
'55-and-newer models as well.
Our GM Performance Parts ZZ4 crate motor
utilizes the HEI electronic distributor, which requires different wiring
connectors than the original points distributor.

pedal assembly are installed. It is also much easier to install the new Early
Classic dash pad while the dash is still disassembled.
