I certainly wouldn't try it unless I knew for sure the pinout voltages/grounds were correct..If they're not, component damage can occur.
 
If you don't have one/can't borrow one, you can buy an el cheapo multimeter that will do the job like this one from Walmart or just about anywhere auto parts are sold for about 10 bones..Then remove/rearrange the terminals in the component-end as necessary per the pinout diagram..No biggie..The component-end pinout is industry-standard.
