i just bought a 2002 cherokee 4 horse with LQ and it has power cord for external plug in. it says 220 or 110v, but can i wire a harness (since the existing plug is for 220) to plug into 110v and not have to flip a switch for the power panel inside the trailer to recognize correct power load?

First most power cords are 120V 30 Amp not 220V 50 Amp. Make sure how many prongs are on the cord. Three prongs usually is 120V. What size LQ do you have? Who did the conversion? I doubt you have a 220V 50 amp power cord, it is very unlikely in a LQ.

Yes it is a 220 plug. What you are looking at is a plug for a home or portable welder or dryer. Should be 2 large spade or blade prongs and a round prong on the plug. Go to either Walmart or a local RV shop and buy the adapter plug and then you can plug into a standard 110 outlet. No need to flip any switches.

Hogtownboss do you know that his trailer is 220V? An RV plug is not 220V it is 120V 30AMP. Hooking up to 220V will blow out every electric device in his trailer.
Brrr you need to contact someone that knows that trailer and can tell you how they hooked it up in the past. As I said before most LQs do not have 220V 50amp service in them.

Hitch and Go is correct. You will blow every apliance in your LQ. Be carefull! You mostly likely have a 30 amp 120 volt connection. Go to your RV store, buy an adapter, plug it into a 20 amp outlet in your house or gargage and don't expect to run every appliance in the RV at one time.

READ the post again, did not say his trailer was 220, his plug is! So is the one on my trailer, but it is a 120v 30 amp service!

most likely your trailer is a 110 volt trailers made for the USA are but a trailer made for another country would be 220 volt , even if the trailer cord end has 4 prongs and says 50 amp service it is still 110 volt yes there is an adaptor end for that plug that will allow you to plug into a standard 15 amp 110 volt plug go to your local RV store and buy one . You will not be able to turn every thing on at once but will be able to use your trailer . check out your fuse box it will have the info you need .If you can not find what you are looking for give me a call and I will try and help you . 574-294-1269 Randy

I suspect that this is something that the previous owner did for his own convience. If it truely is a 50amp 220 plug
Which ususally looks like this.
The previous owner may have had a 220 outlet near where he parked the trailer and wanted the convience of plugging into that plug. If the trailer has some sort of a break out box that can break 220 into 110, Then you could plug into a 220 circuit and run 110v appliances in the trailer. If the previous owner was cheating, he may have had a 110v trailer, but a 220v plug on the house. So he could have just not hooked up one of the power legs when he installed the plug, Allowing him to use this type of plug but only drawing 110v.
Look at your trailer and see whats there. Start by looking at the plug. What plug do you have on the end of the cord? Is it molded on or was it added latter and screwed or clamped in place. If it really is a 220v plug and it's not molded on. I probably would take a moment and open it up and verify if all the prongs are connected to a wire. You can also look at your distribution center. Does the main panel support two phase power. 220v will have a Black, Red, White and ground wire inside the cable.
Unless it's a pretty sizeable RV, I've rarely seen 50 amp 220 plugs on the cords. Most trailers have a 30 amp 110v which is like the first picture earlier in somebody elses post.
