Probably a simple question but I'd thought I'd throw it out there.

1. The camera needs 12v that obviously you don't want running all the time so I would pressume you could bum it of the reversing lamp circuit??

2. The head unit has an auto switch function that puts it on the units reversing camera mode with 12v in. I could install a rocker switch but where could I get 12v from in the cab that only is available in reverse?

I don't think there is an ECU pin or fuse ot dash indication. Any tips?

Cheers

the reverse light is of a separate relay not through the ECU so find the relay and wire it up to the HU and u could also add a rocker switch so the camera could be turned on even if the car is not in reverse or to disable the camera. its up to u how u exactly want to wire it. note i guess u could get away without the added relay but i have never installed a camera so i wouldn't know

and does the HU have a 12V out for a camera ? if not use the above im guessing but wire it to the camera as well?

If the camera is of the acc that means it would be on all the time when the car is on and as it is a night one also the little leds would be on when not needed.

Anyone know where the 34 GTR reversing relay is?

You can piggy back power off the reverse lights if you just want it to work when in reverse depending on current draw?

I use a 8 channel external video switcher, but mine has a few extra sources and screens to deal with.

you can get one for under 30 bucks if you look around. or hook up a relay to switch it on . search for Bosch relay guide. it has a lot of good ideas in it.

      Wideband is worth setting up if only for tuning purposes. I would not mess with the ignition system unless there's a misfire. HKS crank trigger is popular out here for the relatively easily sourced Denso crank sensor, not a bad idea to install as well regardless of power level on a standalone. Boost leak test is worth thinking about. Oil pressure sensor tied to a fuel cut isn't a bad idea either. Getting the tune figured out is a good idea. Without putting eyes on it and getting under it there's no way for us to tell you exactly what it needs but most likely you're down to the last 10% that will make a big, big difference in how happy you are with the car.

      Has anyone put in brand new full carpet? (not floor mats)

      By PotatoCake · Posted

      Doing a refresh of my 33 and can see a few websites stating they sell the entire main carpet for our cars, but they all have generic photos which is fine, i understand they are custom made to order.  Just seeing if anyone has got it done or had any experience with this, as i would only want to do it if the fit and finish was as good as oem https://carmatsdirect.com.au/products/moulded-carpet-or-vinyl-for-nissan-skyline-r33-1993-1998-coupe https://knoxautocarpets.com.au/moulded-carpets/nissan/skyline/skyline-r-33-1993-1998/

      Any plans for E85? If so, add flex fuel sensor.   I'd probably add in the sensors I mentioned above if the Link will support using them for engine protection. With water pressure, you need to be able to effectively set it that "If temp > X, and pressure = atmospheric, shutdown" as at running temp, you should be able to read pressure in the cooling system. If pressure suddenly disappears, it means the water went some where, and this is a quicker reaction than waiting on water temp to go up (Which, can take a little longer than you'd like, considering it now has to wait for hot air to heat it up) Oil pressure, Oil temp, both would be on my list too if you're looking to add sensors. Wideband O2. And at least one EGT sensor. If you're feeling deluxe, put in individual runner EGTs. Single EGT sensor is more so forget about a specific number, get used to "What is normal EGTs", and then keep an eye on it, if it starts going away from "normal" it's a sign something is wrong (Also, things like the tune can still start going out of spec, but EGTs may not show it, for example one injector starts running leaning, so ECU richens everything up, now 5 out of 6 cylinders are rich, and running cool, with one cylinder lean and running hotter, so it's not perfect) Then there is your other things to look at non sensor related, but you may have already done, or have underway, and that would be things like building a sump for more oil, and better oil control under high G-Forces (Cornering, brakes, acceleration). Basically, the above is worth looking/thinking about, if the ECU can do protective stuff with it, and you continue to use it how you are (Drive it to the track, thrash it, drive home, repeat once every 3 to 4 months)

      Can also confirm these work a treat for most balljoints and bushes. If you have access to a big rattle gun, they make the job so much easier and quicker, compared to using a socket wrench or shifter on the c-clamp 👍

      Its sort of street but got used for circuit sprints on account of I never drive it on the road because I dont have the time to spare. So it usage was sits around for months at a time then gets driven either 50 or 250 kms to the track followed by 20 laps followed by 50 or 250kms home followed by stuck in the shed until next time. So yeah neither fish nor fowl. Just dont want to break it on the track as a preference. Hence the fairly short sensor/mod list. Probably more worried about it pinging itself to destruction more so than anything oil related.
