I looked up "diode" in the CAPS program and it shows 2, but Part Number, MB084716. Diode, Chassis Wiring,Blue, Conn Type, 1.5A.

I have a 92 2.4L truck and I ran it under my VIN. Now looking at the wiring diagram, these do not come into play where your talking about, as a matter of fact, the there aren't any relays between the Alt. and distributor except for the MPI Relay. are you possibly referring to the Power Transistor? it's directly connected to the Coil.
