Hi There

R32 RB26 into R33 GTSt. Long story short (my project nearly completed) some of you allready know the skyline body wiring (Lights, wipers, speedo, oil pressure guage ect...) runs to the ecu. I obviously allready have the standard R33 GTSt body wiring in the car.

R32 body loom is different and therefor Rb26 wiring loom is different as signals from different guages are sent to different pins of the ecu so the wires may need to be cut and pasted into the correct position in order to make things inside the car including fuel pump, and outside (headlights) work.

QUESTION: Diagram, links, ideas for cutting and pasting/ rewiring the R33 GTST Body loom to suite R32 RB26 so I can have fully operational engine running accessories.

I have searched far and wide with not much luck, I have both service manuals (R33 gtst and R32 GTR) but if somone has a human friendly diagram that actual people can read that would be extremely handy.

Thank you :)

So I have discovered after pulling the dusty old loom out from storage that the R32 actually has 3 body loom plugs whereas the R33 only has 2 so I am going to have to direct wire them to the correct places. but

still if anyone has one of these diagrams they can send me please :)

yeah i have workshop manuals for both but they are just wiring diagrams and are waaay too complex for the every day person. If I could get my hands on a pinout diagram for the plugs and I knew exactly what pin needs to be swapped to what pin it would be do-able. Otherwise I guess my only other option is to pay somone a buttload of money

Thanks but I can get the ecu pin out diagram but I am talking about the body loom plugs located inside the car next to the ecu itself and I need to know what wire connects to what, the same plugs that connects your lights, horn, wipers, oil pressure gauge and all of that very useful stuff

Hey mate I've got the perfect guy that does conversion wiring, 1 day turnaround and no need to take the car to him all you need to do is take the loom, very resnobley priced also. although he's located up near redbank plains, if your still Intrested swing me a pm.

    • 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
