I'll start by saying I have zero affiliation with these guys.
But, it's companies like Piranha that scream to me why I pay a fair price for brilliant service versus a cheap price for junk service from place like 4WD Supercentre.
My Cruiser went in there initial about 6 months ago based on a recommendation. They installed 2nd battery, rewired all my sockets, installed an Engel plug, redarc brake controller, Anderson plug, GME, etc
The job was the neatest I have seen. Add the fact they alerted me to a minor rust issue they discovered and threw in a recovery bag and beanie.
I dropped the car I again today to have some spotties fitted and my winch wired. Wow... The neatness of the job again was A1.
So if you are in Melbourne and need anything electrical like lights, winch, brake controller, UHF, 2nd battery, etc... then make the effort to visit Piranha Off road. They also do CT work and drop you off at the train station in a modded Zook 👍😀
No, not the cheapest. Yes, the best. Buy once, buy right.
