Greddy Gauges Wiring

[AmuroRay555]

Ok so I start the install of some electronic gauges from Greddy ( Boost and Water Temp ) and there's four cables, Power Constant 12v, Ignition , Parking lights, and ground. The ground is easy, to the frame. I'll test with my tester when I get 12v with the ignition key and when I turn the headlights, for the ignition and the parking light cables. Now for the one with power source 12v what am I suppossed to do with this one?
Thanks in advance

As the car burns to the ground. You really need to quit giving such poor tech advice.


Everything can be pulled behind the radio.

Ground to chassis.
+12V switched to blue ignition lead.
+12V constant to orange/green backup lead.
ILL to red/blue dash light lead.
