Hi Everyone!

This is the deal. I have a 1992 Integra GS. Now, I have these EUROLITE (Electro-Lumicent) gauges I want o install. They are blue in colour and glow bluish at night I guess. My question is, how to install this becaue they have this special inverter or whatever, whose wires have to be somehow connedted to something inside, and I dunno what. There is a black and a red wire ( - and +), now what do I connect them to in order to get electricity to them. I guess I would have to disconnect my bulbs behing my dash. Has anyone done this before.

So i have 4 gauges (rpm, speed, oil, temp.)
one wire from each gauge goes to inverter
from inverter a black and a red wire have to be connected .....where?
