V35 Cruise Control Install Into A Pm35

[YEE-HAA]

HI

I wanting to hear from anyone with a 12/2004 onwards V35 350gt skyline preferably auto, or even a PM35 who has successfully fitted cruise to it to please reply.

I'm trying to find the speed wire for my PM35 and as much as Leon has helped me (Thank You VERY VERY VERY much Leon ) unfortunately his car and mine are different in the wiring dept.

I was hoping to pick it up off

1) the navigation unit with cd drive, or

2) the navigation transfer unit which is bolted to the ecu in my car, or

3) as a last resort the ecu itself.

If you have a wiring diagram for the above parts for your v35/pm35 or you just know the color and location of the speed wire that would also be of great help to me.

At the moment this seems to be the only hurdle I need to jump and any help would be greatly appreciated.

I've spent many hours trawling the net for wiring diagrams all to no avail.

Thanks in advance guys.

PM Chris Rogers.. he will be able to help!

Have you thought about tapping in the speed sensor wire for the audio unit? That would be present in the loom from the CANBUS in case there was an audio that needed it.

This was one of Leon's options for installing the Cruise in the NM35, but I know for my installation, I actutally used the feed from the ECU. On my V36 Skyline, I only needed to tap into the OBD2 connector and that gave the Cruise brain, the speed and brake pedal signals..

I have attached an extract from the 2005 G35 audio service manual that gives some wiring info.

Hope it helps.

not sure about the NM35, but the V35 does not have the speed signal wire on the audio unit like the USDM G35 does.

I was looking at connecting this up when I installed an G35 HU, but I couldn't find the speed signal wire that suited. The one taped to the Aircon pipe used for the Cruise install is not the correct signal for the G35 HU.

Speed is done down the CAN line, the ecu doesn't output it and nor does the dash afaik. The speed signal comes from the ABS computer, not sure you want to go stuffing about with that either.

Are you sure that plug isn't taped to another loom?

[nickcorr]

Yes, not the engine ECU, the Tranmission ECU...

Thanks for that Nick.

Yes I did consider Leon's option of the speed wire @ the audio unit, but on his car he has 4 plugs with the speed wire clearly identified and my car only has 3 plugs, of which only 1 of the plugs is identical in wire colors and its not the one with 'his' speed wire in it.

I've found my obd connector but again I'd need a relevant wiring diagram to find out which wire is what.

I've been told by the supplier of the cruise that my car 'should' be running speed down the can line and on a analogue line, hence why I got an analogue cruise kit and that's what Leon is also supplying from memory.

I was looking at the 'engine' ecu where the signal inputs to it (btw my car doesn't have an external trans ecu, its built inside the trans).

Your correct I don't want to mess around with the abs module either.

I've found a spreadsheet which talks of a speed wire which apparently is pin 2 at brown 4-way connector, LH of steering

column taped to climate control duct but Im yet to look and confirm this, that was for a skyline 350gt.

I have attached a picture which I believe is the a/c hose greg and the spreadsheet are referring to and I've circled in red.

Correct me if Im wrong.

Thanks

Hi Frank.

The extract from the US manual does only show 3 plugs going into the audio unit... Page AV-10 plug M39, the biggest of the 3..

This also shows that the data output from the LAN-CAN needs to be converted before it can be read. This is shown on the diagram as the Unififed Meter Control Unit.

As my V36 uses the normal OBD2 protocols, unlike my M35, I was able to use a generic cruise that is able to read the speed and brake light switch through the LAN-CAN system.. so only taping into 2 wires there.

Nick

Did you put cruise in your m35 then, if so did you just use Leon's version of instructions?

[nickcorr]

Hi Frank,

Yes that was exactly what I did.. Tapped into the tramsission ECU for the speed, 2 connections to the brake pedal then the power. Also used the supplied stalk controller as I had a Momo steering wheel, which does not work with the OEM switches.

Installation on the V36 was even easier for the cruise, but getting the controls connected though the steering clockspring was a nightmare!!

Sorry to go a bit off topic here, but Nick what cruise control unit have you got fitted to your vehicle? If you don't mind me asking.

Yes well thats where my problem lies, in mine doesnt have an external trans ecu like yours, and I checked last night I also dont have the wire taped to the a/c duct that i circled in my previous post.

Unless mine is more like your V36 in that I can tap into the obd plug.

How did you come to find out you could do that on your V36?

Do you have a wiring diagram for the obd plug?

Thanks

My V36 is 2009 MY and was a global car for Nissan as the G37, hence why it was straight forward to get a cruise control arranged using the normal OBD wires. I also have a bluetooth dongle connected to the port, which works with my Gamin sat nav to give trip computer functionallity, additional gauges and diagnostics. It is that conventional.. This unit would not work on my NM35.

Pretty certain that the PM35s do not run the conventional ODB2 protocols, so unlikely you will find a digital cruise that will get the signals though the OBD2 port working correctly on your car.

Did you look at that extract I uploaded for you? The G35 series 2 also run a 3 plug audio like your PM so it might be the same with the speed sensor wire. I think that speed output is part of the ISO standard wiring for the speed sensitive volume feature.

This wire does not exist on the V35. So I wouldn't be surprised if it is just a USDM thing.

Okay, no problems I'll drop it...

Just find it weird that speed sensor for audio would be on the NM35/Series 1 V35 but then removed for the PM35/Series2 V35...

Those Nissan engineers.... Crazy guys...

Hi Nick

Yes I did look @ the manual you supplied,and though i took photos of my wiring earlier in the week, I dont think they are good enough because i cant see all the way round them, so I will look @ them again with a copy of your diagram and see if it matches up.

[sonicii]

yep.. the fact that the G35 gets factory cruise, but the functionality doesn't even exist in the ECU in the V35..

[YEE-HAA]

OK

So it's confirmed now.

I have rechecked my wire colors and have compared them with 2003-2009 g35/g37 sedan and coupes and the usdm I can say without a doubt, are different to my car @ the least.

Does anyone have a V35 factory service manual?? PLEASE

FYI Here's what my M39 plugs consists of, assuming the wire I need is in fact in this plug.

Sorry to go a bit off topic here, but Nick what cruise control unit have you got fitted to your vehicle? If you don't mind me asking.

I have this VDO unit;

http://www.autostrada.com.au/nissan-cruise-controls.html

Which I bought from a different supplier, as autostrada were not doing the V36 units at the time..

But they do sell them on eBay now...

Well worth the money and a straightforward installation with good instructons attached for interest...
