I opened mine yesterday and looked at the instructions - the instuctions make it seem like you don't need to unbolt the bumper beam, but it makes a lot more sense to put it between the bumper and the chassis.

all lights work and im not pulling power thru the taillight harness so its fine.
I got a Modulite as well. What wires did you tap into (there appear to be a couple of bulbs that light up for brake)? And the tail lights just seem to be power to the LED/fiberoptic type lights in the tail light assembly.

Here is what I could find that I think will work:

Left side of the car in multibulb assembly wires:
Left Turn: Blue wire with green stripe
Brakes: Purple with Yellow stripe

Left side of the car on Tail light bulb harness:
Tail Light: Purple wire with Light Blue stripe

Right side of the car in multibulb assembly:
Right Turn: Blue wire with Brown stripe

I assume the "bulbs out" occurs when the trailer lights are connected. If not, I do not know how to "fix it". If my guess is correct and it's only when the lights are connected, you might try changing the jet ski trailer to led lights. I have them on my boat and like them better for a couple reasons. First, they do not corrode and loose the contact when the trailer sit unused. Second, they draw very little power. Third they do not get hot so nothing bad happens if you do not disconnect them before dunking them in the lake.

Even though your setup is not supposed to take it's power from the light circuit, my guess is that it is to some degree and dropping back a lot on the current may eliminate the bulb out signal. Even if it does not, the led lights have advantages.

I just used a cheap set from harbor freight. They were $40 or less. They work fine.

Yea my BULB out light is on most all the time now.. but oh well..
even after the $75 modulite kit.. I was hoping the system would be fooled into thinking the system was OK... but BMW has fine tolerances in this case.

Oddly enough, I wasn't aware of the bulb out light being on when I towed that little track trailer home.

Now that I've replaced the right tail light on that little trailer (was broken when I picked it up), I'll have to hook up to it again and see if I get the indication or not.

I went with the Modulite 119146 and a 10 Amp fuse on the power wire (but my trailer has the minimum lights so hopefully around 8,5 Amps at most):
http://www.etrailer.com/p-119146.htm

If I blow the 10 Amp, I can go to a 15.

But I don't know for sure yet if I didn't have the bulb out light - I should be able to re-check this weekend.

Most small trailers like the ones that are rated for that hitch are the standard 4 pin flat connector. The modulite unit comes with the connector that mates to the trailer connector below

I use a round four just because it looks better and is easier to connect. But then I have to have an adapter for when I rent a trailer or tow somebody elses.

Check etrailer.com or an Ausie trailer supply company for connector adaptors

http://www.etrailer.com/c-a.htm

We have to do the same thing over here if your truck has a 7 pin and the trailer a 4 pin (or vice versa)

May as well just order the 1-1/4" hitch though, cant believe you cant buy that in Australia!

pfjones have a wiring kit for our cars, its big bucks though.. Wonder should I go with that?

I'll re-hook up my trailer this weekend now that it has all 4 lights (6 bulbs in total) in place and recheck for the bulb out signal.

---------------------------------------
On your wiring needs, what trailer will you be hooking up to (how many lights does it have)?

Finally getting a little of my trailer re-furb done.

- powder coated the tire rack uprights
- added safety chains
- pumped up tires to 60 psi
- added DOT reflective tape
- tidied up the wiring
- new smaller, current looking tail lights
- added a spare tire mount on the front (spare tire to come) - had to mount it horizontally because of the tire rack up front. At least until I get the 6" hitch extender.

I'll just add some eyebolts around the perimeter to tie stuff down to and she'll be awesome on the drive from HB to Atlanta and back.
