Trouble Shooting the Installation of
AutoReWire Turn Signal Switches from Al at AutoReWire.com.
Most problems that come up during the
installation of these switches are problems with the wiring or
with the flasher relays.
Below are key things that need to occur before the switch is
installed.
Make sure that if your vehicle has an existing brake light switch
that you have removed the original wires going from the switch to
the rear brake lamp bulbs. Also make sure that you have
separated the Right and Left side wires from each other.
If you are installing this switch with an after market wiring kit
you will only use one flasher relay for both the turn signals and
the hazard lamps. If your wiring kit has two prong flashers
you need to rewire the fuse block to accept a three-prong flasher
for the indicator lamp on the turn signal switch to operate
properly.
If you have turn signal indicator lamps in the dash and do not
want the indicator lamp in the turn signal switch to function you
can use the two-prong flasher as supplied in the wiring kit.
Do not connect the Blue wire from the turn signal switch.
Wire the dash indicator lamps into the appropriate Front Turn
wiring.
Specific wires and what they do:
The turn signal switch is powered by two separate power
sources. One is the flasher relay and the other is the brake
light switch.
Black Wire - supplies power from the Flasher Relay to the Turn
Signal Switch for turn and hazard.
Blue Wire - supplies power to the Indicator Bulb in the Turn
Signal switch. Requires that the Switch housing be properly
grounded.
Red Wire - supplies power to the Turn Signal Switch for Brake
lights
Yellow Wire - supplies power from the Turn Signal Switch to the
Left Front Bulb.
Green Wire - supplies power from the Turn Signal Switch to the
Right Front Bulb.
Orange Wire - supplies power from the Turn Signal Switch to the
Left Rear Bulb.
Brown Wire - supplies power from the Turn Signal Switch to the
Right Rear Bulb.
How the switch functions:
When the turn signal switch is in the neutral position and the
brake light switch is activated (closed) the turn signal switch
sends power to the rear brake lamps via the Orange and Brown wires
on the Turn Signal Switch.
When the turn signal switch is switched to the Left it sends power
to the Left front bulb via the Yellow Wire and to the Left rear
bulb via the Orange Wire. Power is supplied from the L
(lamp) terminal of the flasher relay via the Black Wire. If
the brake switch is activated (closed) only the right rear bulb
will illuminate via power supplied from the brake light switch to
the Brown Wire. The indicator bulb in the turn signal switch
will flash; power is supplied from the P (pilot) terminal on the
flasher relay via the Blue Wire.
When the turn signal switch is switched to the Right it sends
power to the Right front bulb via the Green Wire and to the Right
rear bulb via the Brown Wire. Power is supplied from the L
(lamp) terminal of the flasher relay via the Black Wire. If
the brake switch is activated (closed) only the left rear bulb
will illuminate via power from the brake light switch to the
Orange Wire. The indicator bulb in the turn signal switch
will flash; power is supplied from the P (pilot) terminal on the
flasher relay via the Blue Wire.
The turn signal switch housing must be properly grounded for the
indicator lamp to function properly.
When the Hazard Flasher Knob is pulled out all four turn signals
bulbs will flash with power supplied by flasher relay. Brake
lights will not function.
Flasher problems:
If you are using large filament bulbs front and rear a thermal
flasher will work just fine. Thermal flashers for the
various voltages are: 6 volt = 535, 12 volt = 550, 24 volt = 234.
If you are using a combination of large filament bulbs and LED’s
or a combination of large filament bulbs in the rear and small
filament bulbs up front you will need an electronic flasher or you
may need to use an LED flasher that has 3 prongs with a ground
wire.
If you are using all LED lamps you will need an LED flasher that
has 3 prongs AND a ground wire.
The list of flasher relays that is provided with the wiring
diagram has a list of flasher relays known to work and others that
should work based on the manufacturers published information.
We have not found any way to make the indicator lamp in the turn
signal switch work with a two prong flasher without using a couple
of extra relays. It is much easier to use a three-prong
flasher and avoid any hassles down the road.
Beware:
Some three-prong flashers have the X and L terminals
swapped. That is the X terminal is in the 3 o’clock position
and the L terminal is in the 9 o’clock position as viewed with the
P terminal at the 12 o’clock position.
There are many new flasher relays that have been designed for
modern vehicles and many are labeled and sold as LED
flashers. They have terminal pin outs that are marked E
(earth), L (lamp) and B (battery) or + (positive 12 volt), L
(lamp) and – (negative 12 volt). These are essentially a
two-prong flasher with a ground terminal and will not work
properly with the AutoReWire turn signal switch. Only use an
LED flasher that has 3 prongs with a ground wire or a 5 Prong LED
Flasher relay when using ALL LED lamps.
Resistors can be added to all LED systems to increase the
resistance required to flash a thermal or electronic flasher.
Simply install a 6 Ohm 50 Watt resistor between each of the front
lamp wires and the vehicle ground.
Any and all comments are welcome.
