Antena lead?

[ITDAWO]

Hey all ive taken my head unitoff my old car and pulled the old cassete out my lanos and the antena lead goes straight into the back of the old head unit? rather than just a plug like my new one, how do i attach the antena inot my new head unit?

[daewoomofo]

it should just plug in, all if the head units iv had in my woo's it just pluged back into. there should be a round hole in the back of the head unit for it to go into, just like the stock one.
