Question '05 gx - low cost receiver hitch & wiring

Just got my first Lexus from an individual. '05 with 74K with services every 5K from local dealer! Looks great, no wrecks, was CPO.

I need a light duty hitch for a small utility trailer. Can I bolt on a universal step bumper hitch to the four holes under the middle of the back bumper?

Also, the wiring harness plug under the rear left seems to work fine when I plugged a round-7 to flat-4 adapter into it. ?? Can I just use that for my trailer lights? All the right terminals seem to be powered correctly with running lights, blinkers and brakes.

Thanks

I'm also new to this forum stuff. Hope I'm doing this right.

The 4 holes are there for the class 2 hitch (I think rated for 3000lbs) that Toyota sold, but I could not find one anywhere when I was I looking. Never found a universal that matched up, so I went with the class 3 hitch from Lexus. The problem with the set-up you are talking about is you need to remove the hitch cover on the bumper cover unless your 05 already has the cover that has the notch.

Personally I would recommend getting the class 3 hitch. It's still bolt on but gives you the flexibility to tow heavier loads and you don't need to remove the hitch cover on the bumber cover. If you don't want to fork out the coin for the one Lexus sells call Toyota parts, it's the same hitch for the 4 runner. Or try your local automotive store and or ebay...

Since you have the tow package already everything should work, all you need is the adapter that plugs to your trailer connector.

This may sound too simple of a question, but how do you remove the hitch cover? Do I have to remove the whole bumber? I see blue tabs that I can get to with needle nose, but I'm afraid I'll tear them up pulling them out.

Thanks for the reply. AT least I am ahead of the game with the wiring.

Etrailer has an especially wide choice for the GX470: http://www.etrailer.com/hitch-2005_Lexus_GX470.htm

Etrailer is where I bought the hitch I have on my 2000 LS400 -- I thought their service and prices were excellent.

I never removed it, didn't want to cause I didn't want to screw around with it cracking paint or something like that, not to mention it won't look good with it removed unless you replace it with the cover with the notch which will need to be painted to match. That's why I bought the lexus class 3 bracket/receiver. It looks cool and you hardly notice it. It sits tight under the bumper cover.
