is this connector F50 brown in the center of the picture? is this the alternator external diode that gives the power to wire lg which goes to the ignition relay and the ecu? it looks like it has more than one diode in this connetor if it is the diode.

 

Ok F50, I'll mark that. Yeh LT GRN and YEL on sides. Shows only as One diode dude. Waita minute,, might be like the Haynes and other manuals. That is it's present in both starting and engine control so they just go to "diode" box from yellow wire. Then the engine c side shows it. It's about tblshooting from different ends and know you end up at that same diode on the lt grn.

i had to assume earlier that is was a dual diode. the yellow and green wires in the diagrams do show that this is probably what i was looking for. i'm unsure what the other side /diode is for.
