Is it possible to just buy the pyro for the edge? I would like to look into installing an edge pyro in my drivers side exahust manifold (I have an autometer on in the passenger side feeding my EGT gauge) in case at some point I borrow someone's edge box before I have the $$ to buy one of my own.

I hooked up my ISSPRO pyro to BOTH my guage and Attitude with no problems. Just add some leads where the guage is connected to the pyro lead to connect to later.
