...
'panels' => array (
...
'lbl_...' => array (
...
<number>=> array (
<number>=> array (
'name' => '<your_field_name_of_relate_to_Contacts>',
'displayParams' => array (
'field_to_name_array'=> array(
'name' => '<your_field_name_of_relate_to_Contacts>',
'id' => '<your_field_id_of_relate>',
'<field1_of_Contacts_module>' => '<field1_of_Opportunities_module>',
'<field2_of_Contacts_module>' => '<field2_of_Opportunities_module>',
'<field3_of_Contacts_module>' => '<field3_of_Opportunities_module>',
),
),
