Circuits Wired Through the Ignition
The Backup Lamp circuit is powered on when the ignition key is turned to the ON position .
After the connections are made by splicing into the optional body harness, the body components will have power when the
similar chassis components receive power.
For instance, when the right hand turn signal is activated and the right hand turn signal light flashes on the cab, the right
hand turn signal light on the installed body will also flash.
Connecting Ignition Circuits
Ignition circuits are tagged as follows:
Right Turn Signal - The right turn signal wire is tagged RH TURN and is green/black .
Left Turn Signal - The left turn signal wire is tagged LH TURN and is yellow/black .
Backup Lamp - The backup lamp wire is tagged BACKUP LP and is pink/white .
Ground - The ground wire is tagged GND and is white .
Auxiliary Power - (Standard config for chassis built after first quarter, 1998)
The auxiliary power circuit wire is tagged AUx PWR and is blue . Used for TRLR ABS if there is a trailer .
Do not use for other purposes if auxiliary power is used for trailer applications .
This aux power circuit is a 15 ampere capacity circuit in the ignition circuit . Install a 15 ampere fuse in the
fuse panel (locations F79) behind the dash panel . This aux power circuit can be used only when the igni-
tion switch is ON .
Circuits Wired to Battery
The following circuits are wired directly to the battery through a fuse and switch .
Auxiliary Power
- optional if there are no trailer connections .
Brake Lamp
Tail Lamp
Clearance Lamps
Right and Left Turn Signal
When the optional body harness is properly connected, the similar circuit in the body will also have power. If the chassis
clearance lamps are activated, the body clearance lamps will also be activated.
Auxiliary Power in Battery Circuit
The auxiliary power circuit is a 15 ampere capacity circuit connected directly to the battery . Install a 15 ampere fuse in
the fuse panel location F36 behind the dash. Use this circuit whenever you need power for auxiliary equipment. There is
continuous power to this circuit (when the batteries are charged) even when the engine is off.
For example, if the van body has interior lights or floodlights, these can be wired to the auxiliary power circuit and switched
ON from inside the van.
Connecting Battery Circuits
Battery circuits are tagged as follows:
Auxiliary Power
(optional w/o TRLR connections) - The auxiliary power circuit wire is tagged AUx PWR and is blue .
Brake Lamp - The brake lamp wire is tagged STOP LP and is red .
Tail Lamp - The tail lamp wire is tagged TAIL LP and is brown .
Clearance Lamps - The clearance lamp wire is tagged CLEARANCE LP and is black .
