Plug the head unit into the
wiring harness connector.
Feed the primary servo cable
(250cm section, covered with
black mesh sleeve) through the
firewall into the engine bay.
Often there is an existing grommet that can be used for this purpose. In any case, it is important to ensure that the lead
is protected where it passes through the firewall to prevent wear or damage.

- Page 3 Contrary to popular belief, the spring pre-load DOES NOT need to be adjusted to suit different boost levels. Unlike other valve types on the market, the Deceptor Pro II will stay shut under full throttle conditions regardless of boost pressure or spring pre-load.
- Page 4 Maintenance All GFB valves are designed to be as maintenance free as possible. In most cars the small amount of crankcase and rocker-cover blow-by oil that is directed into the intake system is enough to keep the piston well lubricated. However, in some cases oil deposits or dirt can dry out and create a build-up on the piston that causes erratic operation or sticking.
