The best thing to do when installing a new harness in order to
protect it while checking your connections.
Using a flasher unit or a circuit breaker from the local auto parts
store. Connect a wire to each terminal and the install in series with
the battery cable, between the terminal and the cable end. This will
protect the entire harness while you are checking that every thing
works. You will not be able to leave the headlight on very long or
crank the engine over but every thing else will be fine.
Then if there is a problem the circuit breaker or flasher unit will
open before there is any damage to the harness.
Also remember to install an inline fuse on the red wire on the back
of the head light switch, This way you will protect the tail lights,
marker lights and dash lights.
Another option is to install an inline fuse in the white wire that
goes under the car at the rear of the intake manifold, This will
protect the wiring going to the fuel pump.
