Tips please?

So me and my SO rescued at male kitten a while back who was throw out on our road and he’s been super good! We plan on getting him neutered soon.

We went to petco and decided to adopt a Male cat who just caught our attention and instantly connected with us.

He’s a little cautious towards our other kitty.

What are some tips on some ways to get them to bond a little ?
