Wiring HEEELLPPPP!
Ok so im to the point where im testing my front harness. My headlights work,park lights work,side marker,gauge cluster works,highbeams work. Foor some reason i have no power to my steering column harness. No blinkers.When i unplug the harness and test all the wires..i got nothing. If i touch test light to Black wire which is horn it makes my flasher tick. Ive got power to my starter,alt.,fan relay. Anyone have a direction to go? Do i need to hook up my rear harness for everything to work?. Im STUMPED!

Re: Wiring HEEELLPPPP!
You should have a hot wire going into the switch. Check the fuse & the flasher.

Re: Wiring HEEELLPPPP!
Harness is brand new. I checked all the fuses. The harness is Horn,lf turn signal,rf turn signal,hazard flash,turn flasher,lr turn,rr turn,stop lamp switch. NONE have power coming out of fuse panel

Re: Wiring HEEELLPPPP!
and starter wont turn over either. Maybe start at key switch and go from there?

Re: Wiring HEEELLPPPP!

The turn signal circuit is powered by a 12 gauge brown wire from the key switch ACC terminal. It goes to the fuse panel. This diagram shows the brown wire coming into the fuse panel and powering the green backup light wires and the purple wire which then goes to the steering column connector for the turn lights. The purple wire goes through the turn signal flasher on it's way to the column connector. You flasher might be blown and not allowing power to go to the column connector. I suspect that it's a problem with the brown wire or the fuse panel since you do not have brakes either. The brake light switch is powered by the orange wire on the right side of the fuse panel which also powers the dome lamp and the headlight switch for the parking lights, tail lights and the dash lights. i see that those work so it would appear that you have power to the fuse panel just not on the brown wire. I believe it also powers the hazard flasher as well. Start at the key switch and look for the large brown wire on the ACC terminal. Looking at the steering column connector, the wire for the horn should be on the end of the connector and it should be black. It runs from the horn relay to the column connector and on to the horn button where it grounds when the button is pressed. This activates the horn relay and blows the horn. Are you sure your flasher is ticking or is it the horn relay. If it were the horn relay then the horn should blow. If it is your flasher then you should check that the turn signal wire is not swapped with the horn wire. The fact that you have no power to the column connector indicates that the wires are probably ok. Do you wipers and heater fan work? I think they are powered by the brown wire as well? There are three wires going to the column connector that should be hot. The brown hazard wire and the brake switch wire (white) are hot with or without the key on and the purple wire with the key on. The starter problem can wait unless it's also key switch related. You can determine that by applying a 12 volt jumper to the purple wire on the key switch with the shifter in park or neutral and se if the starter turns over. Post back after you check the brown wiring and let us know if you have power to the purple wire on the column connector. You will need to connect the rear harness for the rear lights to work but you can check for power on all the harness connectors with it disconnected if you have a multimeter.\ I assumed you stepped on the brake pedal when you checked for power on the white wire on the end of the connector?

Re: Wiring HEEELLPPPP!
Ok just checked. There IS power to brown. There IS power to purple with key ON. No power to white. my brake system is not hooked up yet. I checked and it was the horn relay clicking not the flasher. I notice with key on i put left turn signal on and you could see a faint light on cluster and side marker but it was not flashing. I put the test light on side marker when it was faint and the test light was real faint as well. Thank you for your help this is great. I dont know if this helps but i also made a grounding post for the sidemarkers,headlights,fan,and parking lights. All of them hook to it. 1 on each side of the truck.

Re: Wiring HEEELLPPPP!
Ground the gauge cluster and headlight switch body.
Ground the battery to the engine. I like the early motor mount holes on the front of the block by the timing cover. Ground the body and frame to the engine. Since grounds are sort of automatic they get overlooked. Gotta have `em. |

Disconnect the steering column plug and take the half that goes to the truck harness. Turn the key on and start with the purple wire.Make sure it has a full 12 volts on it. If the test light is dim then the wire does not have a full 12 volts so it's best to use a voltmeter. Jump it to the left front turn signal light The light blue wire in the connector. The front turn signal light should come on bright and the dash turn light should come on bright as well. Now jump the dark blue wire for the right side front turn signal and dash light. If either one of them is dim then it has a poor ground on the bulb or socket. Now jump the yellow wire for the left rear turn signal If you have it wired up. Is the light bright or dim? Jump the dark green for the right TS light, bright or dim? If all the lights are bright then the problem is in the TS switch If the marker lights flash in the front then they should come on with the turn signals. I don't know which year the factory made them to flash with the turns. They should come on with the parking and head lights anyway. The rear markers should also come on with the headlights and parking lights. In order for the flasher to blink it needs to have enough lights wired to it to give it enough resistance to break the circuit inside when it heats up and reconnect when it cools. You would need at least the front and rear signal lights connected on the right or left side. Do these tests and post the results.

Ok i have a full 12volts. I jumped from purple to Light blue and BOTH turn signals flash both on lights and dash. Even the dash lights are flashing..weird. Same on the Dark Blue..BOTH signals flash! I also jumped from purple to rear turn signal and they flash fine but not dash lights flashing. The cluster is a brand new classic instruments just plug and go to a new painless harness. Seems as if something not right in cluster?

Re: Wiring HEEELLPPPP!
I'm trying to follow this but are you saying that the right front and the right dash turn light flash together and the left front and left dash light flash together. That's how they are supposed to work.
Or are you saying that all the dash turn lights flash together when you jump either the light blue and purple or the dark blue and purple. And are you saying that the dash instrument lights flash with either side? The dash turn lights are not connected with the rear turn signal lights so they do not flash with the jumper on the purple to dark green or the purple to yellow.

Re: Wiring HEEELLPPPP!
Yes i am saying that ALL the dash lights flash together when jumping either wire light blue or blue AND the front left and right side markers blink together kinda like hazards.
And yes the dash instrument lights flash with the blinker as well, bothe left and right turn signal

Re: Wiring HEEELLPPPP!

If you only have a brown wire going to them and a black wire from the light to ground then they are not supposed to flash but only come on with the headlight switch, along with the parking lights and the headlights. This might explain why all the lights including the dash instrument lights are coming on when you power the dark blue or the light blue wires. Another thing that might cause it is if the turn lights in the dash are wired together or wired different from the dash plug. Disconnect the dash plug and jump the light blue and purple wires and see if the front markers both come on and flash together. If they still do then it's probably the marker light wiring but if they work ok then it might be in the dash or dash plug.

Re: Wiring HEEELLPPPP!
OMG. I think im thinking the side markers are supposed to be turn signals. When i look at a STOCK diagram it shows the parking lights in the GRILL are the turn signals. Is this correct?

Re: Wiring HEEELLPPPP!
Ok I had the dang turn signal light blue and blue spliced in with side markers instead of black on parking lights. That fixed everything on the light circuit. So last thing i need to figure out is why starter wont turn over. Thank you very much VetteVet for your help, it's much appreciated. This is my first FULL wiring project of any kind so all new to me.
