well you'll find theres an accessories wire that goes to the back of your head unit.. i cant rememebr the colour of it off the top of my head. but with a multimetre it should register ~12v when the key is set to accesories or on .. wth my boost guage i wired it up to my illumination wire, as i didnt need to see the light on my guag unless it was dark and i had my head lights on too

but yeah.. unless someone can correct me i would just say get a terminal block and tap into the illumination or accesories wire on your headunit... however this may require the fuse to be changed with added load

cigarette lighter...

i used that as a remote wire in me landrover to wire up a amp/sub... only problem with it is when u got the keys out of the ignition and turn on the radio (only when im cleaning it ect) the sub dont come on... i was prepared to live with that so it was all good

hmm .. my deck isn't wired up so I can have the radio on with keys out .. but ciggie lighter is an easy spot to take 12v from .. cheers.

I'm probably going to go with this. I'm going to make a "harness", which will plug into the cigarette lighter harness to power my gauges. Benefit of this is it isn't permanent...

And, I don't smoke anyways.

      Removing Charcoal Canister

      By joshuaho96 · Posted

      People think it's a waste of space, ugly, etc, generally associate "emissions control equipment" with "bad". These OBD1 vacuum-only systems I'm not a huge fan because I think they don't go far enough. They're wasting some of the fuel captured because they start purging as soon as the engine pulls vacuum. Later OBD1/OBD2 they put an electric purge valve on them to vent only when closed loop is active so the ECU will trim some fuel out. Even later OBD2 with zero evaporative loss the tank is 100% sealed from atmosphere until you run the engine or press the refuel door release. The tank has to take much higher vacuum/pressure spec but you never deal with saturating the charcoal canister and losing some fuel that way. The fuel also lasts as long as it would in a 100% airtight container which is nice when you're dealing with modern E10 pump gas.

      If your luck is anything like mine, what happens is in the process of pulling hoses to get access to the one leak you create many more leaks because every o-ring was on the verge of failing and the strain of pulling it apart caused it to fail. Sometimes life is simple, sometimes you pay twice trying to save once. For the R33 you can still get most AC components from Nissan, I use nissan epc data or amayama to look up the part numbers and then search for the cheapest/most practical way of sourcing from there.

      Boxes of oil?

      By joshuaho96 · Posted

      The dirty secret is there is nothing recyclable about the plastic bag or old plastic bottles either. Our local trash collection explicitly calls it out as hazmat in both cases. Oil-soaked rags + paper towels too. Oil-soaked cardboard is also not recyclable. The most common case of oil-soaked paper like that is pizza boxes, which are explicitly compost-only from the oil. To my knowledge hazmat oil contaminated plastic the only solution is either landfill or "thermal recycling". Most plastics in my experience there is slow permeation of the oil it's holding into the container so it's very challenging to get it 100% clean.

      Import insurance in 2025

      Yes, and since RAA insurance essentially being swallowed up by the same monster that is NRMA insurance and all those other clowns, they are no bloody good now either. We dropped RAA insurance for the house a little while back because they lost the plot.

      I can tell you now, good luck if you're with NRMA (NSW equiv of vis RACV and QLD RACQ). Because NRMA are freaking horrendous to deal with for claims, even with a normal road car. Not to mention even more BS when they're in the wrong and didn't cancel a policy etc when they were meant to and make you jump through hoops for things.
