My SQ6 / Data / Car Loom begins...

[Neel]

The Pectel sensors are NTK Band 10.

I have just checked the reel of thermocouple wire:

Code Number: B80KX

I don't know where you are but they have links to a few countries.

The UK site gives details of the thermocouple wire, I couldn't find it on the US site

Did some more on the ECU loom, its less of a rats nest now.

The first leg of the loom has been twisted and bound with kevlar tape to hold its shape before covering in DR25 TW.





The wires in the back of the 88 way connector have been tied with 'boot lace' to hold its shape before the cover is put on.

Starting to cover the first leg of the loom before progressing on to the rest.





I will finish the rest of the loom legs tomorrow as regards putting the correct wires in them but it is taking a while as I am continuity testing as I go to check each wire is correct.

That looks excellent! Do you have any more pictures, even of the completed loom?

[SAD_Man]

Thanks for the kind comments thedge,

As you can see from the dates my progress is slow but these are some more photos, not quite up to date as I have done a little more but it shows some progress anyway;

A little boring but this is the Comms lead I will use for the SQ6 and the Omega dash (Ethernet, RS232 and CAN):



The start of my Power Junction Box (PJB), although I am currently working on this and it has changed quite a lot since this;





Part of my Omega dash loom;



The 'In car' ECU loom;





Some of the In car sensor connections from the ECU loom;

Why did you decide to use a breaker panel instead of a power control module?

Hi Neel,

I have to say that having gone through the pain of wiring the current PJB, which is a lot busier than the one shown here I have to ask the same question:

I got the parts from another project which means that it wasn't as expensive as the component count suggests

The PDM15 is very new and I have no evidence of them being reliable / fit for purpose (I'm not saying they are not but when I just have no evidence either way)

I have devices which exceed the quoted 20A limit for the Motec PDM's (Heated screens, cooling fans 22A), wiper motor control being particularly unclear

I used PDM's a few years ago on a WRC car and the implementation was far from painless and just need more confidence that these commercial products can deliver on a road / track car, day in day out

Cheers

Thank you for the pics, it looks awesome! Keep posting please, its giving me good inspiration for my upcoming loom

[SAD_Man]

Done a little more on the PJB which is now all but finished:





So very soon I will be joining the "trying to figure out how an Omega dash works" club

Cheers

[Neel]

Beautiful work! Are you building harnesses for someone else now?

[SAD_Man]

Hi Neel,

Thanks for the comments

With the speed I work at these are the only looms I have ever built !!

So no I don't think I will be comissioned to make anyone elses any time soon

Cheers

[SAD_Man]

I'm starting to comission the various parts of the loom that connect together, firstly 'belling out' the whole lot when it is connected from pin to pin.

Part of the process was marrying the Omega dash loom to the PJB and I couldn't resist having a play, this is the Omega in demo mode:

Power up page:



Alarm mode:



And a typical display page:



In reality this only proves out a few wires but it feels like its coming together seeing bits like this powered up.

Progressing slowly with my Omega dash learning:



Managed to connect an EGT and then via the 'Watch channels' options watched the temperature change to confirm both of the thermocouple channels are correctly wired / working.

I did the same with the internal accelerometer watching the output on the dash

Currently setting it up to manually log and download this data with toolset on the PC shown, also confirming the ethernet aspect of the download works

Once this is done I want to connect the SQ6 and make sure the Omega can read in the data from it

Cheers
