Okay, I just want someone to look at this before I go any further, to make sure I've got it right so far. Running parallel circuits, does everything look correct? I used the factory harness for the cigarette lighter and light bulb.

Circuit A (orange, yellow, and purple at the end) - Positive dimmer circuit, plugged into factory harness.
Circuit B - Blue wire is negative for the lights, black wire is negative for the gauges, plugged into factory ground harness.
Circuit C - Heavy red wire, factory 12v (constant) power for cigarette lighter. Pretty sure I have that right, I didn't change anything. ;)
Circuit D - White wire, thin red wire, will be 12v power from relay.
I'm still waiting for two of the light sockets to come in, so it looks pretty messy. The two metal gauges on the left are mechanical boost and oil pressure, so they only need wires for the lights. The two white gauges are EGT and electric water temp, I still need to run the signal wires. The black gauge is a digital Air/Fuel, the black wire will have its own ground, the grey wire is the signal to the O2 sensor.
So basically I have to run the signal wires and 12v power, ground, and switch wires to the relay and it should be ready to go.
Now a question: For the 12v source to the relay which will power the 3 electrical gauges- would I be okay sourcing the power from the hot wire to the cigarette lighter (the relay would make it switched instead of constant), or should I just run its own fused wire to the battery? Basically I'm worried about overloading the circuit, but I don't know how much draw these gauges will actually put on the system.
