have separate circuits, a 3-to-2 converter has not been
installed.
2.
First, cut the factory turn signal, taillight and brake
light wires, as close to the lights as possible.
3.
Next, install the six diodes in line, as close to the
lights as possible, as shown in Figure 21.
Attach the diodes as close to the vehicle’s lights
as possible, to avoid interaction with other circuits
which may be tied into the center brake light, the
running lights, the turn signals or the brake light
wires. Attaching the diodes farther away may cause
the towed vehicle’s lights to work improperly, and
may also cause damage to other electrical compo-
nents in the vehicle.
4.
On each side, jump the brake and turn signal diodes,
as shown in Figure 21.
foRD ‘neUtRAl toW’ vehicleS
Unless the brake and turn signal diodes are
jumped, the towed vehicle’s brake light circuits will
‘override’ the motorhome’s turn signals — the towed
vehicle’s turn signals will not operate in conjunc-
tion with the motorhome’s turn signals, as required
by law.
5.
Test to verify that the diodes have been properly
installed…
A. If the motorhome has a ‘combined’ lighting sys-
tem…
1. The towed vehicle’s turn signals and brake lights
will both flash (per side) when the motorhome’s turn
signal is on; and
2. When the motorhome’s turn signal and brake
signal are both on (per side), the towed vehicle’s brake
lights will stay illuminated, while the turn signal flash-
es.
B. If the motorhome has a ‘separate’ lighting sys-
tem, the towed vehicle’s turn signals and brake lights
will illuminate identically to the motorhome’s.
