Could you do the legwork in exchange for some tokens that you could exchange in any UK store for beer? I'd only be mithering you when I've messed it up anyway
I might have gotten this all wrong. But isn't the pinouts in the service manual?
I had a page from the manual when I tried to locate a speed signal for my EBC.
Nah, I'm going to do it, I just looked at the service manual, and what I'd already written and thought 'F*cking hell, this could take a while'Originally Posted by Mitch
Have I scared you off?
Yakozan - there's pinouts in the manual for sensors and things that go through connector F4, but there's no pinout for connector F4 itself, listing what every wire does. This is because it's just a junction connector that wires pass through so they haven't deemed any need to describe it.
Would it be a case of finding out where the feeds come from on the S15 to attach to the SR20 connector as per the S13 SR conversion to get the engine to run? Shame they didn't mark it in the manual but like you say, there'd be no real need under normal circumstances as it's only a connector.
Also, is there a way of keeping the speedo whilst ditching the ABS? That was a real problem yesterday on track, so I want to replace the lines and route them straight from the master cylinder to the calipers, but still keep track of how fast I'm going

this is the diagram I used for my S15

I've sort of already done enough to get the engine to run - look at pages 10 and 11 of the SR20 into S13 guide. You'll see all the important signals to get the engine to run and the differences between the S14 and S15 connectors. It'd be a case of swapping around the wires on the S14 connector to match the S15 connector. The remaining signals are mainly wiper and ABS stuff .Would it be a case of finding out where the feeds come from on the S15 to attach to the SR20 connector as per the S13 SR conversion to get the engine to run?

When I had the S15 drivetrain in my S13 I had no speed sender whatsoever, so I made a circuit to tap off the rear diff ABS sensor and convert it to drive the S13 speedo. You could do a similar thing with the Dakota Digital speedo interface.
Alternatively just keep the S15 ABS computer and ditch everything but the rear diff sensor - that's all it needs to keep driving the speedo.
Yakozan - It'll become clear at some point...I think
Thanks again John. I guess I'll need to find the F4 feeds for the Spec S then, or are they same as the Spec R? Apologies for the questions, but I'm more spanners than electrickalness
With regards to the ABS- I can ditch all the ABS pump and all that guff and still keep the speedo? If so, that would be a result. Where does the ABS computer reside-is it behind the drivers seat area behind the interior trim panel?
There's always the remote chance that F4 in the Spec-S is the same as the S14/S14a - in which case there'd be no need for any of this. I guess Albert would know...Thanks again John.

It's a pity there's no service manual on the spec-S though
Yep, I reckon the ABS computer would keep driving the speedo, even with the rest of its bits ripped out. Here's for the downer, wiring-wise though - it's on the ECU harness (little black box near the ECU)
Mitch and John...
Ive got all the pages downloaded and printed from S14 F4 connecter and S15 M60 connecter, from hours trolling through the service manuals. I did this and put the info into an exploded view of each connecter to compare but they seem to use different terminology from one manual to the other so I still couldn't make head nor tail of it!!
Your welcome to have a copy if you want me to send it all to you?
Maybe you can work it out?
Hi,
I'd definitely be interested in a look, I can compare it to what I compiledIf you get a chance, please send it to johnwbennett@hotmail.com
Do you think it might actually be easier to keep the Spec-S harness and just add an aditional custom loom to the engine bay?
Provision for the camshaft position sensor, coil packs and a couple of other bits is all it would need I would have thought... Then just use a PowerFC to run it (no NATS to worry about).
John, I have all of these pages in hard copy so not so easy to send via e-mail... It's easier for me to try and photo copy at work and send by post. There is over 50 pages per connecter...
You set me thinking when you said there was no service manual for the S-spec. So I will take a look at my S-spec loom and see if it is the same as the S15 service manual says, to see if S-spec and R spec uses the same loom or not? I'll try to do this tonight
Ben, that sounds a good idea... I have a power FC, does anyone know if the Power FC is the same for S14a and S15?
The S15 service manual is for the ADM S15s. Both ADM Spec S and Spec R are SR20DET.
The plug is the same, but a couple of the pins are in different places (it's listed on here somewhere)
Ben, cheers, I'll look it up.
Mitch, I asked Albert on S15oc how he did his conversion and his answer was funny but not helpful... something like he got some man to do it! LOL
Mitch are you taking your car to Peter at Fabricage for a measure up? If not I will try to get mine over to him? We need to find out how close an S13 one is? Or it's a made to measure for the S15?
Right, I have just checked they M60 connector on my Spec-S harness and all but one wire is the same as the service manual for the S15 which Nicely said was ADM SR20DET S15.
The only difference was pin 6 on mine is Pink and the service manual says it should be Blue-green. This is page EC-123 Overheat (cooling system)
