Need some help finding some info on the wiring for factory r33 setup....

but mine has the optional amp and stacker.

Im looking to upgrade the amp and headunit and remove the stacker as it has died (for the second time.)

hoping to find a wiring diagram from the amp and maybe the stack so that i might be able to use some of the factory wiring to install the new equipment.... ie use acc. ON power speakers running from the amp ect.

i have been able to find a fair bit about the factory head units wiring...

but nothing on the optional setup...

Any iteas ect would be great.....

Well, for the amp and speaker wiring.. if you want to reuse the factory cables, it might be quicker to hook up a multimeter?

You should be able to find positive, negative, and then the remote wire when the ignition is on. Really though, you should run new power cables for your new amp, and maybe just use the remote wire. You'd probably have to adapt the input wires to RCA's for your new amp. Not sure how easy it would be to do that.

From there, you just need the speaker wiring. I think you could use the continuity mode of a multimeter to find each speaker. When you positive to one, and negative to the other (power off) the meter should beep. i.e find a wire with a stripe on it (negative) probe it with the negative meter lead and then probe the other wires until it beeps. Then you have one speaker's positive and negative narrowed down. After you have all four, hook them up one at a time to your new amp and find out which is right, left front etc.

As it's a good idea to run new power for the new amp, it's probably not a bad idea just to wire the rear speakers directly off the new amp... since they're just in the parcel shelf. The fronts, sure.. it's thin wire, but it's quicker and easier than running new cables through the cabin.(likewise with the remote wire)

ok that one isnt that bad. the speakers are found on the amp (all 4.) you should be able to ID these with a meter. the best approack would be a small 4ch amplifier in place of the original and run RCA cables to it.

Fair call, Chris. I didn't know this!

Do you know if he can reuse the input wiring off the amp? Is there anything that could be re-crimped onto RCA plugs?

If not, then you can only really reuse the front speaker wiring, and the remote wire. No point using the rear speaker wiring, because the speaker terminals are just above the amp.

If you have to run new RCA cables, yer might as well run a speaker wire for the remote signal at the same time. I ran that, and the front speaker wire to the front.

the last one I did had a TV in it. same setup. everything was in the rear of the car. I pulled the lot out and ran RCA cables to the rear, added an amp and was done with it.

up to you for what you rerun. cabliing was there and it was a low buck job so I reused it.

      Strange issue RB25DET wont start

      By jtha7 · Posted

      Ps i found the below forum and it seems to be the same scenario Im dealing with. Going to check my ECU coolant temp wire tomorrow    From NICOclub forum: s1 RB25det flooding at start up Thu Apr 11, 2013 7:23 am I am completely lost on this. Car ran perfectly fine when I parked it at the end of the year. I took the engine out and painted the engine bay, and put a fuel cell with an inline walbro 255 instead of the in tank unit I had last year. After reinstalling everything, the engine floods when the fuel pump primes. if i pull the fuel pump fuse it'll start, and as soon as I put the fuse back in it starts running ridiculously rich. I checked the tps voltage, and its fine. Cleaned the maf as it had some dust from sitting on a shelf all winter, fuel pressure is correct while running, but wont fire until there is less than 5psi in the lines. The fuel lines are run correctly. I have found a few threads with the same problem but no actual explanation of what fixed it, the threads just ended. Any help would be appreciated.

I found the problem though. There was a break in one of the ecu coolant temp sensor wires. Once it was repaired it fired right up with no problems. I would have never thought a non working coolant temp sensor would have caused such an issue.

      Hi sorry late reply I didnt get a chance to take any pics (my mechanics on the other side of the city) but the plugs were fouled from being too rich. I noticed the MAF wasn't genuine, so I replaced it with a genuine green label unit. I also swapped in a different ignitor, but the issue remains. I've narrowed it down a bit now: - If I unplug and reconnect the fuel lines and install fresh spark plugs, the car starts right up and runs perfectly. Took it around the block with no issues - As soon as I shut it off and try to restart, it won't start again - Fuel pressure while cranking is steady around 40 psi, injectors have good spray, return line is clear, and the FPR vacuum is working. It just seems like it's getting flooded after the first start I unplugged coolant sensors to see if its related to ECU flooding but that didnt make a difference. Im thinking its related to this because this issue only started happening after fixing coolant leaks and replacing the bottom part of the stock manifolds coolant pipe. My mechanic took off the inlet to get to get to do these repairs. My mechanics actually just an old mate who's retired now so ill be taking it to a different mechanic who i know has exp with RBs to see if they find anything. If you have any ideas please send em lll give it a try. Ive tried other things like swapping the injectors, fuel rail, different fuel pressure regs, different ignitor, spark plugs, comp test and MAF but the same issue persists.

      Freddy Plenum vs Genuine options RB25

      My return flow is custom and puts the return behind the reo, instead of at the bottom. All my core is in the air flow, rather than losing some of it up behind the reo. I realise that the core really acts more as a spiky heatsink than as a constant rate heat exchanger, and that therefore size is important.... but mine fits everything I needed and wanted without having to cut anything, and that's worth something too. And there won't be a hot patch of core up behind the reo after every hit, releasing heat back into the intake air.

      There is a really fun solution to this problem, buy a Haltech (or ECU of your choice) and put the MAF in the bin.  I'm assuming your going to want more power in future, so you'll need to get the ECU at some stage. I'd put the new MAF money towards the new ECU.
