INFINITY EMS INSTALLATION
Step 1
Open the trunk and disconnect the
battery.
Open the hood and locate the E-Box on
the left side near the firewall. This is
where the factory ECU (Digital Motor
Electronics or DME) resides.
Remove the four screws using a T25
Torx wrench (late models) or 5mm Allen
wrench (early models). Simultaneously
pull up and rotate the E-Box cover to
release it from the vehicle. This will be
reused.
Step 2
There are 5 DME connectors. These
must be removed in a sequence from the
left to the right (as pictured) or connector
5-4-3-2-1.
First remove connector 5 using your
thumb by squeezing the release tab.
Hold down and pull upwards.
