Roadmaster AddaBRAKE 8800 - Modify Lighting and Connect Wiring

Modifications to the towed
vehicle’s lighting system
continued from preceding page
lightdoestheflashingfortheturnsignal;inaseparate
system(Figure 2), thereareamber orred turnsignal
lightswhichareseparatefromthebrakelights.
2. Next,testtoseeifthetowedvehicle’sbrakelights
willilluminatewiththeengineoff—turntheignitionkey
tothe“tow”position,pressthebrakepedal,andcheck
thebrakelights.
3. Basedonwhetherornotthebrakelightsilluminate,
andthetypeofbrakeandturnsignals,therearethree
possibilities:1)thebrakelightsilluminateandthetowed
vehicle has combined lighting;2) the brake lightsil-
luminateandthetowedvehiclehasseparatelighting;
or 3) the brakelights do not illuminate. Choose from
the appropriate listbelow toinstall either an optional
accessoryoranotherlightingsystem.
  (If you choose to install a system of diodes and
rewire the vehicle’s turn signals, taillights and brake
lights for towing, wiring diagrams are available at
www.roadmasterinc.com.)
1. If the brake lights illuminate and the
towed vehicle has combined lighting…
 …oneofthethreealternativesbelowisrequired.
A. Asystem ofdiodes
(the vehicle’s turn sig-
nals,taillightsandbrake
lightshavebeenrewired
for towing) with an op-
tionalBrake-LiteRelay.
  (Thismethodcannot
beusedinFordvehicles
with ‘neutral tow’ kits.
See “Ford ‘neutral tow’
vehicles,”inthismanual,
forwiringinstructions.)
B. Install a “bulb and
socketset”(alsocalleda
“taillightwiringkit,” part
number155).
C. Install a magnetic
towlightsystem(partnumber2100or2120).
2. If the brake lights illuminate and the
towed vehicle has separate lighting…
 …oneofthefouralternativesbelowisrequired.
A. Asystemofdiodes(thevehicle’sturnsignals,tail-
lights and brake lights have been rewired for towing)
withanoptionalBrake-LiteRelay.
  (ThismethodcannotbeusedinFordvehicleswith
‘neutraltow’kits.See“Ford‘neutraltow’vehicles,”in
thismanual,forwiringinstructions.)
B. Asystemofdiodeswith the diodes jumped.This
methodisalsousedtowireFordvehicleswith‘neutral
tow’kits.SeeFigure15.
C. Installa“bulbandsocketset”(alsocalleda“taillight
wiringkit,”partnumber155).
D. Install a magnetic towlightsystem (part number
2100or2120).
3. If the brake lights do not illuminate…
 …an optional stop light switchmust be installed.
ROADMASTERmanufacturesstoplightswitchkitsfor
anumberofvehicles;visitwww.roadmasterinc.comfor
themostcurrentlistofavailablekits.
 Anyoneofthefollowingtowlightingsystemsmust
alsobeinstalledwiththestoplightswitch:
 • asystemofdiodes(thevehicle’sturnsignals,tail-
lightsandbrakelightshavebeenrewiredfortowing)
 • a “bulb and socket set” (also called a “taillight
wiringkit,”partnumber155)
 • amagnetictowlightsystem(partnumber2100or
2120)
Step C
Install the motorhome monitor
wiring harness in the towed vehicle
 When the components of the motorhome monitor
areinstalledandconnected,anLEDonthemotorhome
dashboardwillilluminateeachtimeAddaBRAKEisac-
tivated,confirmingthatthetowedvehicle’sbrakeshave
beenapplied.
Note: there are two lengths of black wire in this kit,
each with a female bullet connector at one end. Use
the short length of wire in this step.
1. Chooseamountingpointatthefrontofthevehicle,
near the electrical socket, for the end of the harness
withthefemalebulletconnector.Attachtheconnector
withoneormoreoftheincludedwireties.Allowenough
slack sothat a male bulletconnectorcanbe plugged
intoandoutofit.
Note: if there is an open terminal available on both
electrical sockets, you can use the existing electrical
cord to connect the monitor wiring between the two
vehicles. This method eliminates a separate patch cord,
included with AddaBRAKE for the same purpose. If you
choose this method, cut the female bullet connector off,
and attach the monitor wire to the open terminal on the
towed vehicle’s electrical socket. Later, you will use the
matching terminal on the motorhome’s electrical socket
to complete the connection.
