If the IT Analyst position is in any way relevant to the position you are applying for, then you should absolutely put the job on your resume.
The company that you are applying to, should they choose to proceed with you as a candidate for a job, is that they'll contact your old manager to, first, verify that you actually worked for them for the time specified on your resume, and then ask for a basic reference, which pretty much just involves your reputation and work ethic. Some companies will also try to verify what you said on your resume and possibly in your interview as well. My point is, it really doesn't matter whether or not you've stayed in contact; you can still use the job on your resume, and if your manager behaves professionally at all, then they should still give you a good reference, given that you performed well in your previous job.
Also, I would try contacting your old manager, by calling if possible, to get his permission to use him as a reference. As he/she seems to have liked you, he/she shouldn't say no. However, if he's unavailable or no longer works for the company, you should provide a general contact number for the company, so they can at least verify employment.
