I have the same queries.I have sent cubes a pm to see if i can get an answer.

Untill i read the thread by cubes i was undr the impression that i had a s1 motor.

Luky for me i didnt go and get any parts for a s1 and realise that they would not fit.

What are the identifying traits of a s1 engine compared to a series 2?

I have done some tests with the help of cubes.And i have determined that,In order of the afm flow,that wire number;

1.12v

2.Air signal ground

3.signal wire @ 1.4v

What we have to find out is it safe to run the Z32's 12v feed to the ground and why.Can i get some help from others on this question please.

Thnx cubes & zoom

If you want to wire a Series 1 (4 wire style) plug to a Series 2 Loom, you just have to add the extra earth wire for the power supply side of the AFM.

The factory Series 1 earth that the series 2 doesn't have is wired to the front of the plenum with the rest of the earths.

If that helps.

i've done some testing myself also and found the following:

1. Power 12V connecting to pin 49

2. Air Signal ground to pin 26 (note it's not ground)

3. Air signal to pin 27.

So to wire the z32 to s2 afm as follows:-

Z32 AFM R33 S2

A - not connected

B - Air signal -> 3

C - Ground -> to ground

D - Grd signal -> 2

E - Power 12V -> 1

F - Not connected

can anyone correct me if i'm wrong? :)

  • 7 months later...
  • 1 year later...

Just finished wiring up another one so I thought I would add something a little more simple.

E --> Black/White

D --> White/Blue

C --> Direct connect to vehicle body using ring terminal etc.

B --> Orange/Blue

{First colour denotes colour of wire. Second colour is trace colour}

    • 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
