Для начала все свои "неизвестные поля" соберем в массив $arr:

foreach ($_REQUEST as $k => $v) {
              if (strpos($k, '_from_where_') === 0)
			  $arr[$k] = $v;
             }

А затем этот массив передадим в параметр array_merge():

return array_merge($reference_model->get_alias(), array(
			'_currency_id' => array( 'method' => 'get_currency_by_id'),
			'type_id' => array( 'method' => 'get_transport_type_by_id'),
			'_region_id' => array( 'method' => 'get_region_by_id'),
			'_drive_id' => array( 'method' => 'get_drive_by_id'),
			'_color_id' => array( 'method' => 'get_color_by_id'),
			'_affiliate_id' => true,
			
			'_vin' => true,
			'_fabrication' => true,
			'_cilindrics' => true,
			'_price' => true,
			'_mileage' => true,
			'_price_negotiable' => true,
			'_version' => true,
			'_seats' => true,
			'_engine_power' => true,
			'_best_offer' => true,
			'_category_id' => true
		),

		$arr,   /* !!!!!!!!!!!!!!!!!!!!! */

);
