Electronic Control Module Wire Harness Kit Ram Jet 350 MEFI 4. Chevy SB V8 Gen I & II. This module/harness kit is used to convert a Ram Jet 350 from MEFI 3 to the newer MEFI 4 design, which provides a better idle through closed-loop operation. It includes ECM module P/N 88962717, wire harness, P/N 88961967, oxygen sensor P/N 25312200, intake air temp sensor P/N 25036751, oxygen sensor fitting P/N 15156588. Note: If replacing the ECM module only, jumper wire P/N 88963118 is available to convert an MEFI 4 module to an MEFI3 wire harness to retain the open loop system. The ECM is programmed with a "green mode" that controls the rpm for the break-in period. From start up to the end of first hour is 4000 rpm, second hour is 4500 rpm, and third hour is 5500 rpm.
