I was wondering if anybody out there has installed a remote start in a 2006 Mit. Eclipse yet? My question is this: How do you wire up a relay to interupt the 556uw? The key sense wire rests at "ground" but when the key is inserted into the lock cylinder, it turns into an "open". So how do you take an "open" input and convert that to a "ground" or "12volt" output? I talked to DEI and they haven't ran into it yet. Any help would be greatly appreiciated.

I've never used the 556uw before, so I'm not familiar with it.

What are you trying to do with the keysense?  I would guess that you are trying to turn it to an 'open' so that the car things that the key is in the ignition.  Is that correct?  Or, are you trying to disable the bypass when the actual key is placed in the ignition?

It sounds like you should look in to a PNP transistor.  When its biased with a ground signal you can output 5vdc, when there is voltage, or an open, on the base of it, it will output a ground.  You can then use this signal to do whatever you need to do in the car.

Sorry I couldn't be more help, these cars keep getting newer and newer, and I keep getting older and less knowledgable since I no longer install!

cut blue trigger from remote start to 556 U 

put one side on 87a & the other one on 30

this is so the car cant see 2 keys at once
