Help with Suzuki DF140 engine interface

[BlackArrow]

Honda99/ Shanoss

The warning lights are definately disabled if its hooked up the way I explained above. The trouble is that I have not found either a Suzuki or Lowrance dealer or tech that knows what they are talking about in Australia. I had to ring the States to find out where the connections were on my new Suzuki 140, Its a bit sad when Suzuki Australia and Lowrance Australia can not advise you seeing that Lowrance make the cables for Suzuki.

Like you I am not happy running without warning lights and honda 99 your Suzuki dealer does not now what he is talking about because its a bit hard to plug a male to male plug.

What I have done is gone to my Suzuki dealer and got a female 4 pin plug (the same as the black one in the photo above) off an old wiring loom (there are about 4 per loom leave plenty of wire attached to the plug) and 5 metres of 3 core wire. I have soldered the 3 wires to the plug and hooked it into the grey plug and reconnected the black plug for the warning lights. Not quite finished yet but I intend to run the 3 core wire to the rear of my instrument panel and solder it onto the SMIS wire loom. That way the enginge interface is completely seperate to the warning lights.

The Trim guage connection is behind the trim gauage you have to disconnect the trimk guage and plug in te interface cable.

The 4 pin grey connector is called SMIS Adapter Harness the Suzuki part No. is 990C0-88035 they are also called a K8 adapter.

I will give you an update when I complete the job tonight.
I have attached some photos of the SMIS and Interface wireing looms.

Blackarrow,

thanks for the update,

It was my assumption that the plug is female, the suzi guy only made mention of the plug being the same on both the cable and the interface connector.

Couldnt get one from the yammi dealer. will try another tommorrow.

Ok the jobs finished and all the warning lights work and so does the engine interface readouts.

This is how to do it

1. Purchase enough 3 core marine grade electrical cable to go from the motor to the rear of the consol guages (in my case 5 metres),
2. went to my friendly Suzuki dealer (Yamaha have the same plugs) and obtained 2 female 4 pin plugs that he cut off old wiring looms.(the same as the black plug on the engine) Make sure they leave plenty of wire attached to the plug.
3. Correctly soldered the plugs onto either end.
4. Plug one into the grey connector on the motor and the other into the SMIS adapter.

I also intend to obtain a 2 pin Trim plug (same as te existing plug from an old wiring loom)and solder it into the Trim loom near the existing Trim plug that will give me the guage and the digital readout.

I asked our local Yamaha dealer about getting new plugs and he advised that they only came attached to wiring looms.

Have fun, good fishing

Blackarrow,

I am having trouble getting my K7 engines trim guage working on the NMEA network. Did you have to send any power feeds to the trim plug at the sender or have you just plugged it into the NMEA cable to get it working.

Also, mine, being the K7 simply plugs in under the cowl on the starbord side and all worked (minus the trim guauge??) but for anyone having truoble with K8's, PM me and I'll email you Suzuki's Service Bulletins that include schematics etc.

From what I see, all of the connections for K8 engines to NMEA networks take place at the helm end of the harnesses and there are no requirements for anything more than connecting the "helm to engine" harness into the SDS port under the cowling, which in turn brings all engine data up via the existing harness. At least that's what Suzuki's literature is telling me in the schematics.

Seems that this will disable the existing guage set and rely on the SMIS / LMF-400 as the alarm for engine issues.

To Honda 900, the Deitz plug is a water proof system that many manufacturers use to terminate their harnesses, if you know a good marine or auto electrician, they should have a similar system. Caterpillar also do one if you know any of their technicians.

Good luck...

Ok,

so what I can add,

Found a yamaha dealer in capalaba who knew what the cable was, Yamaha does use the Deitz conectors and has a a harness kit that you can get the plug from, however the dealer has to buy in the whole kit. Yam harnesses do use the same plug, @ around $70 for the harness.

My plan is, get a Deitz plug, I dont really like the idea of cutting off one of the connectors at the engine, dont mind chopping up the adaptor but not in the engine bay. I purchased a 25 foot extension cable so I will extend the lowrance network to the back of my boat, tpiece and terminator, straight to the interface cable. should do the trick.

By the way buy the extension from america, $20.69 australia 128.00, how the hell does that work with $30 freight, arrives in 5 days.



have rung 4 autoelectricians 3 havent heard of them and one doesnt have one..

Honda,

Regarding the Deitz Plugs, they are very commonly used in Mining applications but it doesn't surprise me that garden variety Auto Elec's don't know of them due to the expense.

Regarding the whole project, it seems a lot of work and compromise on your behalf because Suzuki may have sent the wrong cable???

The following is an extract from Suzuki's Engineering Bulliten that suggests the K8 engines require no additional wiring or special work to be done other than the K8 adaptor plug. It really needs the photo's which I can't copy from the PDF file I have but I highlighted the key text bold for you.

Maybe the problem is that the wrong plugs are being supplied??

Marine Division Boat Builder Bulletin
Bulletin No. 004
August 15, 2007


The 2008 engine model SDS communication connectors have been changed from an 8 pin
round housing to a 4 pin square housing. Many of you may have noticed the new SDS version 5.0 came with the new style housing and an adapter to connect to 2007 & earlier engine models.

If the SMIS serial bus style gauges are used on DF40 thru DF250 engines it will be necessary to use a harness adapter to convert the existing engine interface connector to the new SDS communication housing. The 2008 SMIS interface adapter is now available and can be
ordered using part number 990C0-88035.

When the new serial bus style gauges are used on DF40 thru DF250 engines, the factory has incorporated the ability to use the existing harness monitor gauge wiring to make the connections at the instrument panel instead of routing a backbone cable to the engine.

At the ECM, there are now gauge connectors A & B (see below). The standard connection sends the signal from the ECM to the monitor warning gauge at the instrument panel. By separating connectors A & B and inserting the SDS communication connector into connector A, you can connect the gauge interface into the 4 pin housing originally designated for the monitor
gauge.

Standard factory connection Connection for digital gauges
SDS Connector
Connectors A & B A
B When using the serial bus
gauges, connector “A” should
be moved to connect with the
SDS connector.
If you have any questions, please contact your Sales Application Engineer.


Hope this helps as I'd be as concerned as you about cutting plugs off and soldering.

Good luck and hope it may help avert you needing to cut plugs etc.. I can email you the various Suzuki bulletins if you want the pictures etc. Just PM me your email,

Steve

Looks like my problem was a crook trim sender so I am all going now on the '07.

you don't have to cut any plugs off. I can asure you that the way I last explained how I did it is the easiest way. Your friendly Suzuki dealer or wreckers will have the identical plugs on old wiring looms to make up the new cable and its much cheaper it costs me $15 for the wire and about 15 minutes to make up.

Regarding the trim I am unable to get mine to work I have read on a yank site that an update is needed, so I will get onto Lowrance on Monday and get it and will let you know how I go.

BlackArrow,

yep, understand the way you did it,

you were lucky to get the wiring harness from your dealer; so far I have tried,

6 boat yards,
4 autoparts places
2 marine electronics specialists
4 auto electricians
3 electronics specialist shops
Haines themselves.

so as you can see, its not lack of trying to find the right connection, my dealer has recommended cutting off the plug as well as suzuki and a yam dealer, so this week in for a service I will have the dealer do it to ensure my warranty remains in tact.

Take 2,

Yep a lot of time and trouble from LEI having put the wrong connector on the cable.

Cheers Honda,

Good luck, sounds like you are close anyway and much wiser for your patients.

I did not think the connectors would be that hard to get off old wiring harness as there are about four plugs to each harness. Getting the Suzuki dealer to change the plugs will ensure your warranty. Just check before cutting the plug that it is not the same one that they hook up to their service computer.
Yes LEI certainly got it wrong a female plug on both ends of the cable would have saved a lot of stuffing around.

Hope you sort it out
