I was wondering if there is a way to connect a cigarette lighter to the 7 pin connection so that I could use an accessory outside the trailer. Idealy I would like to connect the "adaptor" or whatever might work to the plug on the trailer and then have a 12v receptical I could plug into. 2nd option is to connect the adaptor to the back of the truck and have the recepitical attach to the 7 pin receptical there through some sort of adaptor. Anybody have any info on this?

You could but if the tow-vehicle was wired correctly, the terminal that has the 12-volt charge power in your connector will only be on when the key is on, or in the case of a battery isolator, only when the alternator is running.
All you would need to do is get a male 7-way plug, like on the trailer, and wire the two poles of the adapter to the proper ground and 12-volt terminals in the plug.

GM sells one, and probably every dealer you call will have one. It is listed in our catalogs in a very vague way so that it looks like a 7 to 4 adapter. Send me a PM if you have trouble finding one, I'll send you back the part number.

Your OP indicated you want to use the lighter socket powered from your T battery---right?
Some "accessories" are polarity-sensitive---make sure you connect the + connection to the center-pin on your lighter socket!
Get a pair of the long "spade" DC male connectors at the auto parts store......attach them to the lighter socket + and - leads.......plug them into the 12V + and - slots in your T 7-pin connector.....and you're in business......if the lighter socket doesn't have the proper fuse, suggest you add an inline fuse.....also, a little 3M electrical tape to hold the spade connectors in your 7-pin won't hurt....

Isn't this backwards? The spade connectors would slide into the slots on the trailer-end plug but not on the tow-vehicle connector.

As an OPTION, he said he'd use the TV!

If you want to mainly use the connection for around the trailer, then why not come off the trailer battery, and mount the connector where you want. JMHO
