V35 series 2 sedan major bust up

[Blakeo]

Hi guys I have a 2005 Nissan Skyline v35 with the 3.5L VQ35DE. 

Not impressive I know, its my drift car and the wiring harness that goes behind the back of the dash caught fire. 

I have since tried to repair the harness, but being a amateur I think the wiring is responsible for the dash having no power and not being able to start the engine....

I have sourced a series 1 wiring harness, what is the chances it will work with my series 2 at least good enough to make the drift event this saturday??

Otherwise does anyone know any work arounds, I am kind of desperate. 

CHEERS.

P.S anyone with access to the factory wiring diagrams would be majorly benefical please HMU.

If you aren't confident working through every potentially damaged wire and want a chance of racing tomorrow, you need to see if the S1 loom fits.

There are wiring diagrams available for each year of the US cars, so just pick the closest to yours and remember it may not be identical. I've never seen any accurate Japanese (or translated) manuals for any of the post R34 stuff.

Longer term, its probably an opportunity to chuck out all the modern electronics that a skiddy car doesn't want/need. Will probably require an ECU change to aftermarket as I bet the factory one will be grumpy if it doesn't hear from the BCM that everything is good.

Hey Duncan, 

Thanks for replying. The cheapest quote I have been able to get to setup a body loom, as in just headlights, brakes, indicators and have the ecu be standalone is $8,500+gst and will need to buy an aftermarket ecu in the region of ~$2,000.

Does the above sound right? Just seems to be super expensive, I didn't want anything fancy just for the car to drive. 

 

I don't think even an auto sparky would be able to fix the wiring harness, its an absolute mess. Hoping someone here knows if a series 1 harness will fit. I have found the IPDM wiring pin outs are slightly different, but I don't know if that's an issue if I buy the whole series 1 wiring harness with modules.. I guess then my series 2 ecu won't work.

It's really hard to judge if that quote is cheap, expensive or priced correctly. The cost of your harness will vary greatly depending on the quality of materials used, if it's completely sealed, the type of connectors used, etc. 

It's like asking if a quote for an engine build is cheap and giving none of the details of the parts used, machining required etc.

Just a couple of example of what I'm talking about - 

This 18 gauge TXL wire. About $1 a metre - https://www.rapidcables.com.au/txl-automotive-primary-copper-wire

This 18 gauge 44 spec Raycham wire. About $2 a metre - https://www.motorsportelectrics.com.au/shop-by-product/product/16-18-44-spec-raychem-wire-10-metre-minimum-each-colour

1 metre of 3/16" DR25 heat shrink. About $9 a metre - https://www.motorsportelectrics.com.au/shop-by-product/product/raychem-dr25-heatshrink

1 metre of 5mm Jaycar special heat shrink. About $2 a metre - https://www.jaycar.com.au/5-0mm-black-heatshrink-tubing/p/WH5533?pos=2&queryId=40024a8a7b0f399a645d96f628fe16cf&sort=relevance

The cost of these consumables add up very quickly. 

What part of the harness was damaged/what needs repairing?

Essentially the whole dash loom needs replacement, also looks like now the ECU is bricked from possible 12v shorting thru the canbus

I have found one guy local who is a legend, that has parted a series 1 v35 sedan and hoping the loom from this can be used. At the moment I don't think it will work but going to give it a shot. 

 

Cheers.
