Hey guys having trouble finding some instructions on there.

I'm in the process of throwing a few into my car water temp/oil temp/boost.

The biggest issue im having is I got them off a mate with no instructions. I have them all working insofar as lighting up, I have the temp senders hooked up, however the two temp gauges arent reading anything.

I have the gauges hooked up with just the bottom 3 wires, and just have the top power/ground wires unhooked as when I was wiring them in they seemed to light up regardless of whether I had the key turned to ACC or not (wired to stereo power wire).

I'm assuming that its the top power/ground that needs to be hooked up for them to work? If so Ill just wire them up to the ciggarette lighter wires. Could you provide any confirmation on this? (Cbf ripping dash out until I get some sort of confirmation that this is what the problem is.)

Cheers guys,

Greg.

cigarette lighter is a good tap in point if ur a novice dealing with electronics . basically there's three wires to the cigarette lighter ones ur ground normally black then u have ignition power that's connected to the lighter too. then theirs a separate wire going to a globe that lights up ur lighter in the dark. use that wire so u can illuminate your gauges.

personally in my opinion. i would make a central junction under the steering wheel then only send two wires (lighting) to the lighter. that should solve ur " I was wiring them in they seemed to light up regardless of whether I had the key turned to ACC or not (wired to stereo power wire)." problem.

You could always splice into the ACC (blue/white wire) of your stereo so the gauge or gauge lights arent constantly on. Seems like you've spliced into the CONSTANT +ve. I suggest not to tap into the cigarette lighter as you'll keep blowing fuses once you put like a phone charger or radar detector in. Other wise if you dont use your cigaretter lighter at all by all means use it then, easy option.

this is a wiring diagram for my saber gauges. might come in handy for you. not sure if the wire colours are the same, but majority of aftermarket gauges are the same.

oil press

red - to ignition switch 12v(+)

black - battery(-)

orange - to oil press sensor

purple - dimmer/+12v to dim/connect to headlights to activate

oil temp

red, purple and black - same as above

blue - temp sensor

Hope this helps you out and doesnt confuse you. =)

    • Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom
    • I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off. 
    • I checked spark on all cylinders and they all visually have spark with the plug pulled and grounded, but plug 1 is the only one that fouled. This was a running swap that blew up and was rebuilt by a machine shop, put a new wiring specialties harness and did all gaskets, studs, and bolts while it was out.  compression is 135-150 across all cylinders. Aside from that from my understanding with the z32 ecu and maf the car should start regardless. The wiring for TPS and the dual 02 sensor/ dual knock sensor stuff shouldn’t actually stop the car from starting or even running well, (just slightly rich)  they just give fault codes. Car supposedly is supposed to start as long as you have z32 afm and ecu with the nistune base map and that’s info coming from a well known and trusted tuner who does a lot with SR/RB (Rsenthalpy). After more trouble shooting today where I’m at right now is that the cas is sending signal to the injectors they click while spinning the rotor, Fuel pressure is now set at 43psi, all cylinders have good compression and all of the plugs looked great (just wet with fuel) except for cylinder 1 which was very black (cylinder 1 has 150psi compression). all of the coils generate spark if pulled out and grounded out on the head. On the fuel pump car just pops into the exhaust. On starting fluid car will fire off. Hard to tell if all cylinders are firing off but definitley a couple. sounds like all of them but it’s only for 3-5 seconds hard to tell. 
    • Final update!!! Got the front bar fitted and sprayed and all sorted now. My cutouts worked great and the indicators aren’t just falling off. 😂  
    • Is this a brand new LSD? if so, have you followed any break/bed in procedure for it? Usually involves heaps of figure 8 patterns, a fluid flush.
