How do you replace idm on 99 f350 7.3?

To replace the IDM (Injection Driver Module) on a 1999 Ford F350 with a 7.3L diesel engine, first disconnect the battery to prevent electrical shorts. Remove the engine cover and locate the IDM, which is typically mounted on the driver's side of the engine. Unplug the wiring harness connected to the IDM, unbolt it from its mount, and replace it with the new unit. Finally, reconnect the wiring harness, reattach the engine cover, and reconnect the battery.
