The Stovebolt Site Forums The Shop Area The Electrical Bay Tech Tips - How do I wire my turn signals???

Hello,

I bought a Guide 6002 with 7 wires and I am using a 3 terminal flasher.

My question has to do with the Stove Bolt Tech Tip for wiring turn signals (link below). The tech tip is for a truck using the brake lights as turn signals. On my 46 Truck I have separate wires running to the left and right brake lights wired to their own bulb (the brake lights have 2 separate bulbs). I have a separate wire to both the left and right front parking lights. The left brake and parking lights wires are on their own terminal on a terminal board and so are the right brake and parking light wires.

The Tech Tip shows:
-White - brake light switch?
-Pink - left brake light
-Black - right brake light
-Yellow - flasher
-Light blue - left front signal light
-Dark blue - right front signal light

I am assuming the yellow wire in the example above goes to the L Terminal on the flasher and although not included I am assuming their should be a 7th wire that goes to the Flasher P Terminal and provides the signal on/off indicator light on the turn signal itself.

My first questions is, in the example above can I combine the two left wires (pink & light blue) and connect them to my left wires on my terminal board and combine the two right wires (black & dark blue) to my right wires on my terminal board?

Second question is, what do I do with the White brack light switch wire? I am assuming I don't need it because I have seperate wires and bulbs and not using the brake lights, am I right? Can I just terminate the White wire with some black electrical tape?

The chart you are quoting from the tech tip is an example.
It may not apply to your switch.

You will need to follow the tip and chart out your 7 wires with an ohm meter
Or try to search for a diagram for your switch.

You should not have to eliminate any wires from your switch

I did use an ohm metter and I have identified the wires. My problem is I have separate wires for turn signals so I need some guidance, because I am setup different than the tech tip example.

The single brake wire should got to your firewall brake switch.

The pilot wire should be easy to trace back from the indicator light on our switch.

Then You will have the four corner lights you already identified.

The final wire will be the load wire on your flasher

First off, the wire colors you mention refer to a factory switch. They have nothing to do with an aftermarket switch.

"I am assuming the yellow wire in the example above goes to the L Terminal on the flasher and although not included I am assuming their should be a 7th wire that goes to the Flasher P Terminal and provides the signal on/off indicator light on the turn signal itself."

On your aftermarket switch there will be another wire for the pilot light.

You say your brake lights have 2 separate bulbs. I think you are mistaken. I believe that one bulb is brake light and the other is tail light. In order to tie the front and rear wires together at the switch you will need a separate light housing for the turn signals. You will not be able to use the existing wires to the existing brake lights. Then you may terminate the brake light wire from the switch.

If you are planning to use the existing wires, like the switch is designed for, you will need to have the brake light signal going through the switch. This is the route I'd recommend. You will also need to convert the front light sockets to dual filament and run new wires for them.

Please see my comments below in red.

I still don't have answers to my questions.

First questions is, in the example above (and I know those are not the color of my wires but I understand the concept) can I combine the two left wires (pink & light blue) and connect them to my left wires on my terminal board and combine the two right wires (black & dark blue) to my right wires on my terminal board?

Second question is, what do I do with the White brake light switch wire? I am assuming I don't need it because I have separate wires and bulbs and not using the brake lights, am I right? Can I just terminate the White wire with some black electrical tape?

I'm pulling this answer out of my ear ...

There were a number of different lamp styles and switch hook ups to create turn signals. Each required a different number of wires to the switch on the steering column. You may be trying to connect your switch in a way that it was not intended.

#1 - Totally separate bulbs (or filaments) for turn signals. Does not use existing bulbs (filaments) for parking, tail, or stop. Separate signal lamps were often mounted on the front fenders and on each side of the rear.

#2 - Uses existing front parking single lamp bulb (single filament) and uses existing rear brake light bulb (filament)

#3 - Uses separate bulb (filament) for front signals, and uses existing brake light bulb (filament) for rear signals.

Your setup seems to be like #1. Each blinking signal goes to a unique filament that is not shared by other functions such as brake or parking. I believe that the "#1" separate bulb installation is described in the 1951 Accessory Installation Manual for TRUCK turn signals. See pages before and after the diagram. Trucks did not have right hand tail and brake lights as standard equipment.

The 1951 installation for CAR turn signals has seven wires like your switch. It uses the brake light filament in the existing car tail lights. Cars had rear tail and brake lights on both sides.

OK, I now see that you have dedicated signal bulbs at all corners but I don't understand why you want to connect wires. If there is one terminal on your board for front and rear left and one for front and rear right, you only need one wire to each. Connect the front signal wires to the terminal board. Terminate the rear and brake switch wires.
