3. Usinganotherofthesuppliedspadeconnectors,at-
tachthebareendofthebrakesignalwiretotheoutput
ofthediode(Figure3).
4. Routethebrakesignalwirethroughtheenginecom-
partment, to the driver’s side of the firewall. Use the
same route asthebreak away wiring harness and/or
themotorhome monitorwiringharness, ifthatis con-
venient. As before, avoid lines, hoses, moving parts
or“hot”componentssuchasexhaustsystems.Where
appropriate, use wire ties to secure the brake signal
wireinplace.
5. Routethebrakesignalwirethroughthesamehole
in the firewall as the break away wiring harness and
themotorhomemonitorwiringharness.
6. Replacetheprotectiveloom,whichyouremovedin
stepone.
Step E
Attach the firewall grommet;
attach the wiring connectors
1. Cutthroughtheincludedfirewallgrommet(Figure1)
ononeside,andslideitoverthebreakawaywiringhar-
ness,thebrakesignalwire,andthemotorhomemonitor
wiringharness.Fitthegrommetintothe1/2"holeyou
drilledinthefirewall.Feedtheremaininglengthsofthe
brake signalwire and the breakaway wiringharness
through the grommet. Then,seal the grommet with a
siliconesealant.

2c.Ifthetowedvehiclehasmagnetictowlights…
Note: additional connectors and — depending on the
application — additional wiring will be necessary to wire a
magnetic tow light system.
• Peelbackasectionoftheprotectivecoveringnearthe
plugontheelectricalcable—enoughtouseatestlighton
thewiringand,later,toattachtwobuttconnectors.Then,
usingatestlight,findtheleftandrightcombinedbrake
andturnsignalwires.
• Cutoneofthecombinedbrakeandturnsignalwires,
andattachtheendswithabuttconnector.Runasmall
lengthofwirefromthebuttconnector,andattachafemale
bulletconnectortotheendofthewire.
  Attachamalebulletconnectortoanothersmalllength
ofwire.Usingoneoftheincludedspadeconnectors,at-
tachtheotherendofthewiretooneoftheinputsonthe
diode.
  Repeatfortheotherbrakeandturnsignalwire.
  Beforetowing,connectthemaleandfemalebullet
connectors.
• Trimtheprotectivecoveringovertheelectricalcable;
wrapanyexposedwiringwithelectricaltape.
• Connecttoground—atbothvehicles,connectawire
toanygoodchassisground.Beforetowing,connectthe
groundwireswithaseparatecable.
2d. Ifthetowedvehiclehasataillight(“bulbandsocket”)
wiring kit…
• Makecertainthatagroundconnectionexistsbetween
thetowedvehicleandthemotorhome.Otherwise,thewir-
ingisidenticaltothecombinedbrakeandturnsignallight
