So, here a little guide to build your own consult connector Very Happy

the basis of it is the mainconnector of a defective ATX-powersupply.
First you have to imprint the flags of the Pins with a needle to get them out.
Then, you take the pins of a 25 Sub-D plug and put them into the holes of the ATX connector pins and solder them.
From the ATX-connector you have to cut off three pin-lines.
After that you press the flags of the ATX-pins out again and plug them into the ATX-connector.
Finally you take two plastic pieces and put them into the slots of the Connector. (i took them from a CD-spindle cover) to prevent for false connection (as already happend to me Embarassed

)
Hope i wrote in understandable english Wink

Here the connector again with the Plastic pieces mounted.

this connector is working great, with no signal interruption !!!

Very Happy

Im making one of these at the moment, but for my atx plug, I had to use a small screw and tap the pins out with a small hammer, there was no plastic tab to push to get the pins out like an automotive plug, and they came out quite easily.

Using a screw will also work but is the not so elegant away Smile

Hello Chri.

I've made two of the connectors.
They fit and work flawless.

Thanks. Smile

Hey, i like the concept of DIY, but what goes on the other end and where did you get the schematic to figure out what goes where?

Chri · Joined: 28 Aug 2004 Posts: 68 Location: Austria, Europe

The other end is directly going to the Conzult Interface ^^
It's described on the Shematic Interface Diagram from PLMS-Dev. which can be found here: http://www.plmsdevelopments.com/consult_if.htm

But what wires go where in that connector? I have a 1998 SR20det engine in my Z, I need to check my codes and i have no dash harness so i need to make this plug. I found 3 data wires in my ECU diagram, then i heard i need a power and ground. But where do they go in that clip? And will I be able to read these codes on a ODBII scanner or only the consult? I heard there is software for a laptop that will alow me to read the consult codes, is that true? if so where can i find it?

Thanks!

Hmm, as i know the DIY Consult is OBD I , so if you have a OBD II ECU , this won't work.

For OBD II you need other Interfaces, the only resource in know for this is http://www.scantool.net/resources.htm

From witch car is the engine ?

It's from a 1998 Silvia S14 (after the minor changes). The ecu pin outs match the 99-01 S15 ECU perfectly.

Then its probably a OBD II ECU .
In This case i can't help you further.
Maybe someone else could help you from here

Hello,

I have been looking for such a DIY plug for the consultbut what i wondering is, why do others show electronic diagrams to make it work yet you only solder pins to the connector and then plug it into the consult directly?

How does this work and why do others show that you need an electronic board to make it work?

Planing on buying a 80$ consult cable from someone but if this truly works like those ones, i'll do it myself.

The thing whitch is explained here is only the Plug to connect the DIY Conzult to the car.

The thing you will get from the guy is probably the Cable with the electronic (Conzult Interface) included in the Pulg (SMD build).

maybe I didn't explain myself correctly

I am currently programming an interface in c++ to talk with my Skylines ECU. Can I just build this connector which will connect in my DB9 port and then to the Consult port directly or do I need the cable that has the electronics in it?

As I understand it, you need the electronic board to connect a PC to the Consult plug

Chri · Joined: 28 Aug 2004 Posts: 68 Location: Austria, Europe

The interface is a piece of hardware, soyou are programming the software ;)

Yes, you need the calbe with the electonics in it to get it working

the way to get the car on the screen:
Car with consult Connector <-> DIY Cable <-> Conzult Interface hardware <-> RS232 Cable <-> Laptop/Pc with your software

If the cable you will get have the Conzult plug and the RS232 plug then the Interface hardware should be already in the RS232 Plug
Is it maybe looking like the interface from www.blazt.biz ?
