Electrical Noob Needs Help...

[rjstaaf]

Have a 2001 Mustang GT and I am working on installing a Dakota Digital Oil Pressure gauge.

Working on getting power to the gauge and let me say, I HATE WIRING!

I was hoping to not hack into the wiring harness, would rather use an add a circuit. The problem is the add a circuit is limited to 10 amps max.

I can't seem to find a circuit in the fuse panel that has the required 10 amp or less fuse and is switched rather than constantly powered.

Seems all of the circuits in the panel that have 10 amp and under fuses have constant power.

Could really use some help here...



Thanks

How much power do you think you need? 10 amps is more than enough for a gauge.

If interested in getting a full copy of the wiring diagrams and service manual for your car, I maybe able to help. PM.

Here's the panel layout.

I looked at a couple of Dakota gauges (you didn't say which you have.)

For example, the HLY-1031 requires just 150mA (0.15 amps).

The HLY-1032 takes even less: 100mA (0.1 amps).

Use an add-a-circuit with a 2A fuse and you'll be golden.

hmm. I am running an add-a-circuit and powering 4 speedhut gauges and a Cyberdyne gauge. Boost, AFR, Fuel Press, and Oil Press and the Cyberdyne is a water temp. Not a single problem.

If you get too concerned about how much amperage you'll be drawing, add a relay and run the stuff you're planning to add off of that.

Thanks for the input guys.

Upon further research and input from other forums as well as calling Cooper Bussmann tech support, I found that it is the new circuit that is limited to 10 amps because of the size of the wire pigtail.

I wound up putting the add a circuit in the circuit for the gauge cluster which is 15 amps and used a 5 amp fuse for the added circuit.

The install went smooth after that. I still have some loose ends to tie up like painting the steering column pod to match as well as trying to find the break in the wire for the factory oil pressure gauge which is why I installed this one. Neither is a high priority right now but I will eventually get to them...

Here is a link to the Dakota Digital gauge and sending unit I used...

Here is the installed gauge and the VDO sending unit that goes with it...

I just go a air/fuel ratio gauge for my 2001 mustang. I have it all wired up for power but then realized that it has to be wired in to the O2 sensor but my stang has custom exhaust and whoever did it cut the wires to the O2 sensors. Is there any way I can wire just my gauge to the O2 sensor without having to run the O2 to the PCM or is that where the O2 gets the power from to operate?
