 Foot brake wiring is either BLACK/ blue or BLACK/ green at either floor loom, don't pick-up at the pedal, it's data.
DEI and Fortin have dedicated modules for this vehicle; use them or you will be having nightmares.
 
 -------------
 Amateurs assume, don't test and have problems;  pros test first. I am not a free install service.
 Read the installation manual, do a search here or online for your vehicle wiring before posting.
