UVC Wiring Firing Sequence

Can someone give me a little explanation on how the firing function works.

Seems like by the pics depict 4 sets of wires going UVC. These attach to GP's & Injectors?

Thanks Tater

4 plugs total into 2 valve covers. each connector feeds 2 glow plugs and 2 injectors. It splits under the valve cover

Thanks

My logic figured that, but wanted to have someone w/firsthand experience, since I got no manuals.
In the pic of the harness that I have; I see 2 plugs w/circlips that have 2 wires extending from them & 2 FM round plugs with 1 wire; is my logic correct in thinking that the circlips go to the injectors; maybe one to open, one to close injector???

Got a pic or can you describe what the layout of the 4 pins are? Outer pins/inner pins??? Trying to figure what the burned pin that I have found goes to; injector or GP. Both burned pins from different harnesses are the outer pins.

for each plug -in there are 5 pins, 2 outer pins are the gp's, next two inner pins are for the injectors and the middle is common ground.

I did a search for Pics & could not find any under the Tech Files; I hate to ask so many questions, but I cannot find any pics?

Thanks for the input: found some more info!!

Glow plugs ground through the block, one wire to each.

The solenoid on the injectors is not grounded to the injector, so two wires each.

Two glow plugs and two injectors per valve cover connector.

G - I - C - I - G

G = glow plug
I = injector
C = common ground
