Download Installation Instructions 1. Disconnect the engine wiring harness electrical connector (2) from the manifold absolute pressure (MAP) sensor. 2. Remove MAP sensor bolts. 3. Remove the MAP sensor and O-ring seal from the intake mani-fold. 4. Replace MAP sensor connector with the new stage kit connec-tor, shown in figure 3. Rewire connector using the following in-structions along with figures 4 and 5. 5. Make sure that the green O-ring from the production MAP sen-sor is no longer attached to the mounting surface. Put the new O-ring on the new TMAP sensor. Both are provided in the kit. Lubricate O-ring with clean engine oil before installation. 6. Install new TMAP sensor into the intake manifold using only the right bolt as seen in figure 6. The TMAP sensor may need to be tipped slightly to start hold down bolt. Bolt needs to be tightened to 10 N•m (89 lb in). It is recommended to use Red Loctite 262 to help secure the bolt. It is very important that the bolt does not loosen up. 7. Connect the GMPP connector to the TMAP sensor. 8. Disconnect the engine wiring harness electrical connector (2) in figure 7 from the intake air pressure and temperature sen-sor. 9. Remove TMAP sensor bolts and then remove sensor from in-take housing. Make sure to also remove o-ring from sensor or housing. 10. Replace TMAP sensor connector with the new stage kit con-nector, shown in figure 3, which is supplied in the kit.
