hey guys

I have an 88 crx and I plan on installing my gauges myself and write up a little DIY but i need one final bit of help.

the electrical side of things

on the installation guide of the gauges it says i need the following wires to tap into for the gauges

- Connect to Groud of the vehicle (-) [i already know this is the black one]

- Connect to 12V power source (ACC) of vehicle (+)

- Connect to dash light or switchable 12v light same


So i need to know what colour wires they are so i can connect them to the gauges


ALSO would it be better to drain the oil COMPLETELY before removing the oil filter?

your help is greatly appreciated guys thanks
