Calling all 911EP gurus! I have a question about the 911EP millenium and using handheld controllers which top out at 3.5amps per channel. The bar has its own dedicated power/ground, heavy duty which I would be running to the battery (with a fused connector of course...30 amp?). Is the CID box and the +12 inputs just a fancy relay? Meaning I can control it with whatever I want that can feed +12 to the inputs I want? For example, let's say instead of a Star LCS869 I use a Feniex Typhoon, so I can have up to 6 features controllable (takedowns, alley L and R, left warn, right warn, main warn). That's 6 features that would normally use a LOT of amps...but again, the CID is just getting a relay type signal, right?
