I bought an EZ2 Wire kit, much the same as painless, but heavier gauge, and all black with labelled wire, some of the colour get hard to pick a couple of years down the track. The wiring kit of US Ebay, on special, with freight is about $150 cheaper than one in Australia......thats the final cost.
Gauges are Autometer Cobalt series. I'm going for a blue car......blue gauge lighting at night. The autometers are real cheap over there, but I bought a heap of stuff from Summitt at once, overall it keeps the freight cost down.
What I have learned...............ASK THE SELLER TO MARK EVERYTHING AS "RACE CAR PARTS". This immediately drops your import duty from 10% on regular car parts, to only 5% for "race car parts". PLUS FU%^$@# GST
All said and done I've saved about $4,500-00 buying the gear overseas.
