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.

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 :D

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.

    • Well, yes, every CU on the bus is available via the Consult port, but whether the scanner you are using is capable of talking to the TCU, the ABS/TCS modules, etc etc, is what is at question here. Many of them are only for engine codes. So, if you have one of those, you won't know if the ABS is having a bitch.
    • That's now. R chassis Skylines come from a time when the tolerance in the ADRs was a bit more....slack. My car, on 235/35-17, which is damn near the exact same size as the original 205/55-16, is pretty much bang on correct indicated speed across the whole legal range. That's demonstrated with constant speed run over 5km, and GPS speed. It's just the luck of the draw. My particular speedo head has to be the thing that is "calibrated" that way, because everything else (the diff ratio, the gearbox and the speedo drive**) are all same same as most other Skylines. **OK, so the speedo drive is a Navara unit to drive the R32's cable, not the electronic unit than an R33/4 would normally have with teh same gear on it. Otherwise, I applaud your OCD tendencies, and I would do the same if I needed to.
    • Not too sure, I believe the Nissan consult port does everything? Also just filled up the reservoir to full and the light is still on. The float seems to move up and down fine.
    • The speedo's can be very conservative, when my Mazda NC MX5 speedo is showing 118kph, the GPS, and a calibrated radar.... cop mate.....hits me at around 110kph +/- 1 or 2 kph, and that is on a 215/45 17, stock tyres size is 205/45 17 as well, so weirdly conservative with stock tyre size When my Commodore speedo red 116kph GPS had me at 110kph on 255/40 17, so again conservative Google says manufacturers need to set the speedo from 4 to 10% slower than actual road speed.....for safety.....and compliance  After doing some offset and clearance measurements to see what can fit the NC on 17x8 +40, without guard rolling or rubbing anything at my current ride height, I've decided that when my tyres are toast, I'm going to fit 225/45 17 and see where that gets me IRT actual speed of my speedo and GPS/radar From the online calculator I should be still be doing around 5kph under an actual 110kph when the speedo is showing 110kph My ADHD requires that when I'm doing 110kph on the speedo, that the actual road speed is actually really close to that, and not alot slower And going from 205 to 225 still keeps the car within the %/mm allowable in the NSW vehicle rules and regulations, which is nice, as long as I'm looking at the latest version that is.....LOL https://www.nsw.gov.au/sites/default/files/2021-02/RMS-13.464-Light-vehicle-modifications-Vehicle-Standards-Information-No-6-November-2013.pdf
    • Take the value it measured as, and pick the closest range available that is above the reading on the screen.   Also, no point just testing the coils. Read what has been said again. You need to test all your wiring, everything.
