sort of. the tr7 is programmable for many different things for example..... alpine navs require a signal from the foot brake(+) and a pulsed signal and then a latched from the ebrake (-) at the same time in order to use the dvd or nav functions while driving. so you can have a (+) and a (-) being used at the same time or at different times depending on how you program it.
lets say you have a momentary switch (dash switch maybe) you can program the tr7 to send a (+) on the first push of the button and then the next time you push the button it can send a (-) they are also low voltage triggers as well

basically the tr7 could replace both of the timed relays
so it's one of those programmable "smart relays"? I have seen and used them in a 120v AC setting but never in a car. I suppose it's the same concept. Those run about $100 for the basic ones right?
