stalled—thetowedvehicle’sbrakelightswillilluminate
whenthebrakepedalispressed.
To wire the vehicle for towing…
 Therearethreemethodsavailable whichwillallow
atowedvehicle’sturnsignals,brakelightsandrunning
lightstoworkinconjunctionwiththemotorhome’s:1)
installataillightwiringkit(alsocalleda‘bulbandsocket
kit,’ part number 155); 2) install magnetic tow lights
(part number 2100 or 2120); or 3) wire the vehicle’s
turnsignals,taillightsandbrakelightsfortowing.
 Instructionsforthethirdmethodarebelow;instruc-
tionsforthefirsttwomethodsareincludedwiththekits.
1. Afteryouhaveinstalledadiodedownstreamfrom
the brake light switch (Figure 14), wire the vehicle’s
turn signals, taillights and brake lights for towing by
installingsixdiodes.
  Beforeinstallingthediodes,verifythatthetowed
vehiclehasseparatebrakeandturnsignals—oneach
side, there are amber or red turn signal lights which
areseparatefromthebrakelights(Figure2).
Note: if the motorhome has combined brake and
turn signals, use Figure 15 to wire the towed vehicle.
If the motorhome has separate brake and turn signals,
visit www.roadmasterinc.com. Use the ‘Separate towed
vehicle to ‘separate’ motorhome’ wiring diagram, under
‘Support.’
Note: if a 3-to-2 converter has been installed in a
motorhome with separate brake and turn signals, wire
the towed vehicle according to Figure 15.
To test for a 3-to-2 converter, use a test light to find
the turn signal and brake light circuits on the motorhome
electrical socket. If the same circuit energizes both the
turn signals and the brake lights, a 3-to-2 converter
has been installed. If the turn signal and brake lights
have separate circuits, a 3-to-2 converter has not been

To wire the vehicle
for supplemental braking…
If AddaBRAKE is to be installed in any Ford
vehicle with a ‘neutral tow’ kit, do not install a
Brake-Lite Relay. Using a Brake-Lite Relay in these
vehicles may prevent disengagement of the trans-
mission for towing, causing severe damage to the
transmission.
Install a diode, rather than a Brake-Lite Relay,
according to the instructions below.
1. Locatethetowedvehicle’sbrakelightswitchand,
withatestlight,findthe“cold”sideofthebrakelight
switch—the“cold”sideoftheswitchdoesnotregister
voltage unless thebrakesareapplied. Witha 12-volt
meter,verifythatyouhavefound12VDC
+
.
  Then,removethebrakelightfuse,locatedinthe
vehicle’sfusepanel.
Failure to remove the brake light fuse from the
vehicle’s fuse panel may activate the vehicle’s theft
deterrent system, or other electrical system indi-
cators, if the brake pedal is pressed during the
installation. This may require non-warranty repair
to the vehicle.
2. Next,cutthebrakelightwire,afewinchesdown-
streamfromthe“cold”sideofthebrakelightswitch.
3. Installthediodeinline,asshowninFigure14.
  Mountthediodeunderthedashboard,afewinches
awayfromthebrakelightswitch.
4. Reinstallthebrakelightfuse,whichyouremoved
instep1.
S
omeFordvehicles,suchastheFordExplorer,areequippedwitha‘neutraltow’kit.Usetheinstructionsbelow
towirethesevehiclesforsupplementalbraking,andfortowing.
