I recently did a bunch of upgrades to my car and my tuner was in my laptop giving me a base tune for the haltech and he noticed the firmware for It was pretty old. Told me to unplug the coils before he updates the firmware because in the past they have fried on other cars while updating. I found the plug on my car and I can’t seem to unhook it. I’ll post a video.

Push the catch in, slide the two halves apart. You may need a thin flat bladed screwdriver or similar to insert into the split line between the halves to give a little leverage and you may need the tip of some needle nose pliers or similar to convince the catch to push in. These all get stiff and stuck if left alone for years.

You can also spray a little silicone lube into the catch area to try to make it easier to move.

Thanks. That was my next idea was some silicone lubricant to try and free it.

Hey @SeanR32GtSt did you manage to get it loose? if not try insert a flat head into the top portion of the split and use another flat head to work your way around the plug.

they're really tight because they have a water seal gasket all the way around.

Cheers

Appreciate it. Haven’t had the time yet to try. I work 4 12 hour shifts at my local hospital. But I have Friday off to try again.

    • Nope.    Grab a varex and turn it down as you get close to home, win win? 
    • So, I've had my V36 for about a month now and have already copped an "excessive exhaust noise" notification from QLD TMR, reported by someone in my local area. It's a twin as per the original, and can have a bit of a throaty note to it when idling cold 😄 and if I do get up it a bit, it can be noisy, but it did pass a roadworthy inspection before sale, so.... ... but in the interest of being a good neighbour, I do want to quieten it down a bit. Is anyone here running a quiet aftermarket cat-back on their V36 or 370Z? And the big, bold question: does an aftermarket cat-back really make much of a performance difference on these cars?
    • The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.
    • Yep...so unless someone posts up the answer you will need to probe from the ECU connector to the dash plug with a multi meter in continuity mode to trace the wires.  Note the ECU has multiple - and + (and across different key settings - Battery, IGN and Start) and most likely the power is fed from the connector(s) that is normally near the left hand headlight.
    • Thanks Duncan, I am actually just trying to get the Rb turning and running with the RB25DET S2 original loom itself  I am just trying to get it going outside the body and not thinking about the S15 or trying to match anything to the S15 loom at all I am only trying to see if anyone has done this and what pin they found to be the ignition trigger and ECU+/- on the dash connector, that's about it. Thanks
