89 Eldorado

Can someone tell me the difference between P/N 16135056 and 16135066. These are climate control modules for 89
Eldorado with some notes that the connectors may be different. The unit in the vehicle is a -056 and it has failed. I can
only find a -066 on ebay but if it is not interchangeable I don't want to spend the money on shipping to have to send it back.
