I have a question and maybe some of you guys can answer this. I have an 04 Ralliart and on the RRM Piggyback ECU are all of the wires being "T"ed?? Or do you cut the MAS wire and one other wire and connect that from the piggy to the ecu?? I know that many of you have done this install, so I want to make sure I dont screw it up.

 

yes, you do have to cut the MAS, i think its white and red. You then have to connect both of the piggy's wires into the CUT wires.

good luck,

use solder

 

I saved my Directions if you want them
Its Cut Red/White and Connect Green and Purple to the wnds of those.. But what order I dunno right at this time.PM me and I will tell ya then.
