Basic question here.
I have a boost guage i wish to install.
I simply need to know what wires i should use under the dash for power, and ground. there is also a dimming option. These are Megan guages…
Thanks
there are instructions with the megan gauges, but if you dont want any dimming and you want to have the brightest lights i believe you use the dimming wire, (purple or grey) in combination with the ignition power. Check your instructions, or look online and you should be able to confirm what i am saying.
Power will be found in the Ignition Harness.
Ground can be fround from any Chassy Driven Bolt. (Test 1st)
Illumination Wire can be found behind the radio. (Blue Wire with Red Stripe)
