FSV wiring harness question

[notenuftime]

I bought an aftermarket FSV made by BWD, I need to wire in a new harness that i got with it since the original FSV was blade connection this one is a pin. the aftermarket harness is lettered A-F can anyone tell me where i connect my wiring in order?. here is some pictures of the harnesses and wiring.

Do you have a diagram of the new harness? I hope its in the instructions. The original harness is;

Brown/white and red are the valve motor wires

Darkblue/yellow is the wire that goes to the front sending unit

Yellow/lightblue is the wire that goes to the rear sending unit

Yellow/white is the wire that goes up front to the fuel gauge in the dash.

here is the diagram from FSV, here is the way i read it does this seem correct?.
E= brown/white valve motor
D= red valve motor
C=yellow/lightblue rear sending unit
B= yellow/white dash gauge
A=dark blue /yellow front sending unit

Also the Brown/white and red that control the valve motors, which is front and rear?.

There's only one valve motor - the polarity is reversed by the selector switch to change between front/rear.

I am pretty sure that + on red, - on brown selects the front tank. Will check the schematic to make sure.

 

[DrCharles]

yep... front tank is +12 to the red wire, ground to the brown/white.

yep... front tank is +12 to the red wire, ground to the brown/white.

So it looks like Red gets wired to "E" and "D" is brown white?.

 

[DrCharles]

Somewhere on that instruction sheet (looks like the same one that came with my Standard Motor Products valve) it should say explicitly which wire is +12 and which is ground in order to select the front tank... let me know.

Here is what it said. ( If using toggle switch, cross wire as shown. Connect one pair of terminals to a good ground and the other pair to a +12 VDC source through a 10 amp fuse.
If i think i'm reading this right looks like E= red and D= brown/white. thoughts?

 

[DrCharles]

Not trying to be difficult but that depends on which way the switch is mounted and whether front tank is up- or down-toggle...

Somewhere in the fine print on that diagram, I think it still says which wire is powered (D or E) when you want front tank. At least it did on my SMP valve.

I recommend at this point that you simply hook it up to a 12 volt source and see which nipple you can blow through...

found this by Franklin 2 on another diesel site.

1->F
2->E (Main Tank)
3->D (Aux Tank)
4->C (aux tank sender)
5->B (fuel gauge)
6->A (main tank sender)

If this is correct than my red wire will connect to E and brown white to D ?. o ya and toggle switch in cab is up front, down rear.

Everything is working, wired as shown above. DONE.
