  • Spare/Aux wires in harness - FP Gauge

    What are these for? Can I use them to hook up my fuel pressure gauge?

    I also bought a fuel temp gauge... so if those wires would work for that... I might just go that route.

    Thanks in advance!

    Nobody knows anything about the aux wires by the V3?

    They are mentioned in the manual, but no options are listed.

      if you are talking about the blue and yellow wires in the cab to chassie harness, then yes. we put them there for people to hook up temp. gage or pressure gage from the v3. or to hook up what ever your vegi burning minds can think of.

        Now that's cool...never noticed that. Hmm...that would definitely make it easier to hook gauges.

        Good job DFA!!! :cheers:

          I was hoping you'd say that.

          I bought the Nitrous brand Oil Pressure gauge from Harbor Freight. It only requires one wire to go from the pressure sensor to the gauge. So, I'd be able to use the other wire for, possibly, the fuel temp gauge.

          I can probably tie into the current Fuel Level gauge that came with my kit for my lighting and power needs right? I'll be powering 3 gauges total.
          - Fuel Level
          - Fuel Pressure
          - Fuel Temp

          I'll relocate the FL gauge from the steering column to a 3 gauge cluster either above the mirror, or next to my trailer brake by the ash tray.

          Is the elbow on the V3 necessary? My gauge didn't come with one, and I don't think I'm low on space, but if there was a good reason to get one, I would.

          Where would the best place to take the temp? I might just return the gauge and get something more productive for $20, but if it would help at all, I'll just keep it.

          Thanks!

            I don't know how big the sender you bought is, but the sender that comes from DFA (AutoMeter) is too big to fit without and elbow.

              It is about 1.25" round by 2.5" - 3" deep.

                it all depends on where your V3 is on the mounting plate. about 8 months ago we switched the mounting plates from fixed position to adjustable position on the frame. so it all depends on how your V3 is positioned, but most likely you will need a elbow.

                  They are like a buck or two at Lowes. Better to grab one just in case.

                    Yup, getting one on the way home.

                      Another though is to use a steel braided line from the module to the sender. Then you could remote mount the sender somewhere else out of the way.

                      I did this on my Camaro with the oil pressure sender. I didn't want it near the heat of the header nor did I want it subject to all the vibration of the motor, so I ran a line from down below and mounted the sender up top in the engine bay.

                      My only concern would be how those lines interact with the VO....

                      Just a thought...

                        I'm using teflon-lined SS braided hose for all under the hood VO plumbing and had same stuff (only smaller) hooking up mech. fuel pressure to 'isolator'. No issues w/VO.

                        somethin' like this would do ya...

                          I got the solenoid onto the V3. Wired the blue wire to the terminal, and grounded it with the rest of the system. Now I'm moving under the dash.

                          Can I tap into the wires going to the other gauge? These don't draw much right?

                            The harness that DFA made for me just split the power at the gauge pod. you should be OK. John told me to use the yellow just for continuity sake cause that is what they use, but of course it doesn't matter.

                              I don't think the gauge is working. I'm seeing 50psi at idle on #2. Then under load it drops to 20. Then cruising @ 40psi.

                              Oil turns on, 40psi.

                              Something ain't right.
