Everything is hooked up. - Front light is OK....... - High beam is OK............ - Parking light (separate harness because of law here) is OK ........... - Tail light is OK......... - Dome light is OK...... - Turn signal front not OK - Turn signal back not OK - Brake light not OK So starting at top of your list. Headlights work with headlight switch? H4 bulb????? High beams work with dimmer switch? Park lights work with headlight switch? T10 bulb????? Tail lights come on with headlight switch? Dome light is satisfactory. DO YOU HAVE ANY LED BULBS? These may take a special flasher to work. May take a relay or two to work. I will cover the "not" working after we get these answered. I will wait a few minutes and then go to bed. Last edited by AZKen; February 21st, 2023 at 09:52 AM. |

When I install the turn signal wiring harness on the hood they will come off. It's only for testing to connect the wire of the socket with the wire of the harness. I will directly wire to the socket with a crimp connector.

Ok now to the turn signals.
1. I see a pic with the front turn signal sockets laying on the drivers inner fender. Wired and ready for testing. Each socket has a dual filament bulb. Correct? 2. I see in same pic the rear tail light housings with sockets installed. Wired and ready for testing. Each housing has a dual filament bulb.. Correct? I realize some of the test wires are temporary. 3. I see your pic of turn signal connections. I understand you have the truck side all done with packard 56 connector shell and contacts. You have just the contacts plugged in from the switch side for testing, No shell yet, Correct? Do you have the colors matched at that connection? If not matched Please give color to color list. Switch side "in" color and truck side "out" color. 4. You have a wideside bed. Correct? Not "step side". Last edited by AZKen; February 21st, 2023 at 05:39 PM. |

OK, Lets check your wiring.
For the front turn signals. You have a dual filament bulb. That is OK but you will only use the large filament. I see three wires on each socket. This means only one socket wire will be wired to turn signal for each side. One wire not used and the ground will be attached to good ground place near light. Assuming the black wire is for ground. Socket may ground itself to hood when installed. The left front T/S lamp large filament wire will be wired to Light blue switch wire. Right front T/S lamp large filament wire will be wired to dark blue switch wire. (Each of those will have a companion wire to the dash turn indicator bulb. Either two wires from one terminal or spliced. See diagram.) If you test bulbs before installing on truck, the sockets/housing MUST BE GROUNDED. Rear turn next: You will use both filaments on each light. One is from the light switch only(small filament) and one from the T/S switch (large filament). Large filament left rear is wired to yellow switch wire. Large filament right rear is wired to dark green switch wire. Small filaments are spliced together with license light, any way you wish....and they are wired to the headlight switch brown. So three wires going to rear. I usually eliminate the rear connector shown on diagram. This reduces voltage loss, intermittence and possible moisture entry. This leaves VIO WHT BLK switch wires. 1. VIO is supplying the flash signal to T/S switch and is wired to fuse panel flasher terminal "L" 2. WHT goes to one terminal of brake switch 3. BLK goes to horn relay. 4. Other terminal on brake switch goes to headlight switch terminal as shown on diagram. Same terminal as a fused hot. see diagram. Of course some wires mentioned may go thru connectors where indicated on diagram. FIY: When making a turn and at the same time applying brakes, the turn signal switch shuts off the large brake light filament from brake switch power on that side, to allow the large filament to flash. That is why the brake switch is wired to T/S switch. So now you have work to do. Please advise any questions or difficulties. Check fuses.. some could be blown by previous tests/activity.

I checked the wiring. It is as you described. Light blue (blue/white) is the left T/S. Dark blue is the right T/S. The violet wire connects left and right T/S socket. Black wire on each socket will ground to hood or socket housing.
What Violet wire? I said NOTHING about a VIO wire when describing front turn signal socket wiring, You are confusing yourself and confusing me. And yes, one light blue (blue/white) and one dark blue wire routes from firewall connector to the dash connector. I don't care what connectors the wires go thru. I only care about you being sure a wire is connected as I describe, point to point.. JUST LIKE THE DIAGRAM. There is no way I can get any info or confirm anything by looking at the back of your fuse panel. It does not matter what colors you used to build it as long as it is wired functionally like the diagram. I tried to explain where each turn signal switch color goes functionally and used the colors you said you have coming from the switch. Wire the lights as I describe. I don't know all the colors you used for which. Last edited by AZKen; February 22nd, 2023 at 08:04 AM. |
