Hmmm... that doesn't sound right at all... the wiring loom should go along next to the roofline in the channel past the interior lamp just above the driver's shoulder and then back into the engine compartment.
There'd be a wire going down to the door lamp switch but not the whole bundle. Start in the engine compartment... note where the main wiring bundle leaves the engine compartment (should be left side upper). From there, it goes to the front of the car with one wire coming off at the interior light. Pull your interior lamp out and you should be able to see the wiring loom going past.
Over on the right side of the engine bay, there's a wire heading off to the battery.
You can see the wiring loom leaving the engine compartment in this image on the left side. Hope that helps.
