[. . . ] Installation Instructions Part Number: 10. 129. 020K-021 Description: SCHRICK variable geometry intake manifold for VR6 engines Notes: The installation of the SCHRICK variable intake manifold is similar to that of the standard manifold. Some additional work need to be done, compared to the standard intake manifold, due to the 3 part design of the variable resonance system. Procedure: 1. [. . . ] Detach the left hand manifold support, it is no longer required. Torque the fastening bolts of the manifold and manifold-support to the 15-20Nm 10. Fasten the high tension ignition leads of the rear cylinder bank to the plastic brackets on the underside of the intake manifold. Connection of all outstanding components are similar to the standard intake manifold 12. Secure the vacuum tank, solenoid valve and electronic control unit to appropriate areas. Because of the plastic content of the parts it should only be fitted to heat-protected areas. Connect the vacuum hoses and rout it in an appropriate way. Connect the open end to the vacuum hose of the brakeservo. Connect the electronic control unit as follow: a) connect plug to solenoid valve b) red cable to switched + (15) c) black cable to earth (chassis) d) blue cable to rev-counter input signal The rev-counter input signal can be allocated to different terminals / leads for different vehicle types. You will have to determine which is the correct terminal / lead for your vehicle 16. the switching point of this control device is programmed for an engine speed of 4000 r. p. m. at which point the rising engine speed causes the plenum valve flap to open. [. . . ] Please note; Installation of the variable intake manifold will change the performance characteristics of the engine and may therefore invalidate the vehicle registration documentation. A technical assessment at the responsible institution is required. [. . . ]
