Rear Lights wiring...

Jeephammer stressed the use of virgin copper wire. I have just dropped my gas tank and figured since I'm in here might as well rewire the sending unit and rear lights.

Where can I buy virgin copper wire or does it matter for rear lights?

Also, My '72 cj has no smog on it so all I have is a supply line and a vent line. The vent line has no filter and is just open. When I fill my tank to the top it over flows here. I was thinking on making this line longer so it will go to vertical under the wheel well and put a filter on it.??? Any Ideas on what I should do with this vent line???

Thanks for your help.

My vent line goes back up to the fuel filler and vents there so that over flow goes into the tank or on your shoes. And Virgin copper is not needed on the lights, only on the fual sender. Virgin copper has less resistance than standard copper wire so that the guage reads more acuratly.

Do you know where I can find virgin copper wire and connectors? Also, what gauge of wire should I use for the brake wiring?

Lastly, which is the best way connect three wires together?

Thanks again.

About any of the US manufacturers will have virgin copper and not alloy in the wire.

It's the 'China' import crap you have to watch.

I like 'Essex' brand wire, made in the US and it's all virgin copper unless otherwise noted.

You might want to try some 'Trailer Cable' from someplace like NAPA or a big truck store.
That will be several strands of insulated, high grade wire in a VERY tough insulated cover.

Same wire they use between truck and trailer, and from the connector in the front of the trailer to the rear of the trailer.

If you run that inside your vehicle to the hole in the back down to the lights,
You can use the Trailer cable and won't have to use a outer wrapper on the wires.

Industrial grade cables like trailer cable will be virgin copper, and probably larger wire gauge than you will ever need.

Yep, JeepHammer is right on. All copper wire made in the USA is virgin copper, no alloy mix. Essex, Carol, Anaconda are all good.

Thanks guys,

My right brake lights have two wires coming out of them the travel across the frame and pick up my left brake light. Now how do I splice this wire into my left light? I currently have those blue inline splicer thingies...Not sure what they are called but really do not like the connection...

Thanks again for all the help...I can replace what I have easily but really want to know the "right" way to do this.
