Wiring Diagram
Anyone got a picture you can send me of the cigarette lighter circuit, for a '79 F-150. The Chilton's manual doesn't have much help...shows practically just a fuse. There is currently no lighter in the truck, but I have plans to installed one, or a 12V power source.

wrench, i feel pretty sure that the truck is prewired for the lighter. i suspect the hole has a cap installed at the factory. the 12v source is most likely hanging near the lighter location. now you may want to send a message to dennis mi1lion and ask about that diagram.

Under the dash in the main wire loom should be a wire with a 90* female Plug on the end.That slides onto the threaded male connector on the back of the lighter receptacle.
Do you have the lighter receptacle asembly already?
It is a two piece unit that has an outer housing with a serated edge that screws onto the inner housing,the teeth on the outer housing makes a ground on the back of the dash.

I've already looked for the connector, I know what it looks like. It just so happens I could not find the connector. Thats why I'm looking for a diagram. I'm trying to find where the connector comes from...I'm the 3rd owner and there has been some slight modifications.

Okay,
It comes out of the loom just left & above the ash tray when you are looking at it from the seat.
Left of the heater control panel.
This diagram is from a 74.it should be almost the same.
The illustration for the 78-79 is very distorted and doesn't show good detail.
I have an illustration from a 78 E-150 that shows it perfectly.
You decide.

well this is easy for anyone who has ever had their wiring out to answer. notice the picture shows a seperate harnes? the cigar (ford usually called them cigar lighters from way back in the old days!) lighter wiring is a seperate piece and if your truck didn't come with one you won't have the wire. it is not much of a harness, one wire about 10 guage or so with a male plug on one end and a female on the other with another female jumper for the glove box light. and i think it plugs into the yellow three prong accessory harness connector on the drivers side (i will have to double check that). my memory says it is a green wire. hawkrod

i dont' think it plugs into that yellow acc. connector.. mine doesn't. if the trucks got an aftermarket radio, then i'd bet they used it for the power source.... simple way to do it,, run a fused wire from the battery to the cigar lighter

[updated:LAST EDITED ON 11-Dec-02 AT 02:37 PM (EST)]i just went and looked and i was close but not quite right. the harness for the lighter gets power from the glove box light wire not the other way around. there are two green wires coming out of the harness where the glove box light plugs in and the lighter harness just jumpers right there. you unplug the glove box light and plug in the male conector from the lighter wiring and the plug the light back into the female end and then it has a 2 foot or so long lead that goes back to the lighter with a female end that fits on the post. hawkrod

I moved one of those harnesses off my workbench in my garage just yesterday.

Well, I don't have a glove box light. I thought that lighters were standard, but the glove light was an option. There is an after market radio that has a fused line coming from a yellow female connector on the drivers side. An actual wiring diagram/schematic would probably answer everything.
