ECM Fuses and Relay
The two fuse holders (6), that protect the ECM diagnostic system, are located under
the engine hood and are tie wrapped to the wire harness on the top of the engine
bell housing. One holder contains three 7.5 amp (brown) fuses and the other holder
contains three 10 amp (red) fuses.
There is one 12 volt relay (7) mounted to the engine panel behind the air cleaner.
This relay controls the engine fuel pump. To replace the relay, remove the relay from
the engine panel, then remove the relay from the wire harness connector (8).

4. Reassemble the plastic cover onto the fuse holder and securely snap the
cover in place. Replace any tie wraps that were removed, securing the fuse
holders to the wire harness.
