installing electronic gauges

[JDMazdaFamilia]

I bought greddy electronic gauges off another MSP member on here, and I'm in the middle of installing them. I'm only used to installing them by connecting them to fuses on the box but the wires are too short. So my question is where are are easy spots on the MSP to connect wires under the dash area that aren't so far away from the A pillar pod.
I can find where to put the grounds but I need to find a

-source of constant power
- ignition switch source of power
-parking light source

Constant source - battery
Ignition - cigarette lighter
Parking light - green wire on the back of the dimmer switch

As for wires being to short. Extend them

I plugged mine into the rear wiper or the radio fuse in the kick panel fuse box and never had a problem

Thanks 808 I didn't know the green wire on back of the dimmer switch was the light

Np. Someone else told me about that one. I used it to switch from red to blue on my evo gauges when I turn on my lights.
