I have a throttle pedal adjustment box which also does basic cruise control and was wondering if anyone knows where to find the speed signal wire in a M35. It may be a yellow/blue wire on a four pin plug....somewhere.... I am trying to get the japanese instructions translated but was wondering if anyone knows.

The device is a Pivot 3 drive AC in case anyone was wondering.

There is no speed signal I can find, its certainly not going to the ecu as it all goes down the CAN line. Perhaps there is a plug under the dash near the speedo? or there could be one off the auto ecu? It would be good if you could translate the instructions and let me know too.

There is a four pin plug under the steering column on the left side or in the left front footwell kick panel area. This is what a workmate's rudimentary Japanese has told us so far.... and it's not the yellow/blue wire- that's for the brake signal.

As soon as I know more, I'll post it up.

Here's a scan of parts of the japanese wiring instructions and also the engrish manual. The plug I am looking for is N-d on the first page of the pivot 3 drive ac pdf. The middle page shows the location for plugs in the car's cabin and the chart on the last page gives you an idea where the brake plug and speed sensor wires are.

If anyone can point me in the right direction it'd be most appreciated!

Looks good, what did it cost shipped?

Andy told me it was about $320 delivered. That makes it a pretty good deal if it does the whole cruise control thing well. I don't particularly care about the throttle sensitivty control, although it could be an interesting toy to play with for a while.

I'm still investigating the integrated 'factory look' cruise but it won't be as cheap as that. Maybe it's not worth worrying about.

Re the speed wire and CAN; there must have a separate speed wire somewhere cause my info meter doesn't display speed (or anything using speed to calculate like gear position etc) yet all the other info is gathered via the CAN bus (after I reconnected a critical wire in the OBDII connector). I'd be keen to know where this wire is also.

yes its a brown plug. it also has accessories power and the optional extras plug into it. i have something plugged into mine for the remote starter etc. ive seen other stuff that use this plug too

Excellent! I'll have a look and see if mine's been tampered with. Maybe I just need to extend a wire down to the OBDII connector somewhere to get the speed to register on the Info Meter. I'll be in touch...

I have a cruise control fitted to my M35 & took speed sense from the ECU . If you can scan the instruction manual of your pivot 3 Im sure my partner could translate it for you.

Hey Brett, does that include one that I've got? I scanned a few pages to try copying sections into an online translator but it didn't work. Can I send it to you?

Cheers, Leon.

Jeez you guys are awesome. My workmate showed the instructions to his Japanese wife last night and it's "brown plug taped on the car harness" in "back left hand side of the steering". Spot on.

Looks like I'll be busy later on tonight when I get home- I'll let you know how it all works.

Thanks again.

Oh, and I looked up my IM account and the unit cost $321.63 delievered. I think it was 18001 jpy which is a pretty good price for the harness as well...

I think the cruise version (AC) is the up-spec. It's only really a throttle sensitivity controller with the added bonus of cruise function in this variant. I saw it whilst browsing and bought it on a whim. If it works as cruise above 110 then the wife'll be happy and I don't imaging we'll use it as a throttle controller.

The throttle control works but the cruise doesn't. Don't have time to look into it any further at the moment so will try to firm up which of the pins is the speed signal- the diagram shows pin 3 of 4- but doesn't say if looking from behind or infront. Sigh

    • Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.
    • How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP
    • I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use
    • I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
    • You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.
