It should have a standard IR input as well; the RCA jack is for RC5 (which is their own thing; it's designed to connect the receiver to amplifiers and some other components). You can likely get converters (As someone has mentioned; I don't know anything about that though).
An IR flasher is probably easier overall - just bypass the whole thing.
On the SR7005, for example, there's "remote control" I/O (which is RC-5), and "Flasher" in (which is what you want). On older models it may be labeled differently.
