wiring harness

This might be a dumb question but are the ends the exact same or does one end have to go to the motor and other end to the console ?

What harness are you talking about?

I-command Classic Installation Guide

part # 763548 . This is the main wiring harness that connects motors to key switches and binnacle etc.

If you take a look in the PDF document

Your harness is called "Ignition trim/tilt
harness twin engine 20 ft"

In one end there is 2x purple and a black, that's the remote control side.

Cool, so all I have to do is find that end and send it to the center console. Did you buy the simm module ?And if so did you find a place on the motor to mount it ?

the SIM is mounted under the dashboard and plug in to the consolidator hub.

I bought both the classic and digital systems, so I have the SIM module.
But I don’t know if it can be used with I-command digital instruments, since my motor has still not arrived.
I haven't seen any I-command digital instruments using the SIM module, as you can se in this document below.
I-command Digital Info Order
Then I connected the SIM module with the I-command classic instruments, nothing happened.
I think.
Then using a SIM module it will send its information to the EMM module in the motor.
And the EMM is sending the information to the I-command classic instruments.

The way I understand is that the simm module connects directly to the motors emm (the computer for the motor) . So I thought it would mount under the cowling . I might be wrong , but I'll know more after this weekend . I'm suppose to bring boat to dealer on monday, so I'm trying to rig as much as I can myself. The dealer said the more I do the faster I'll get my boat back.

The sim module is not used with the digital I-Command gauges.

This is how you connect the SIM module with I-command Classic

Sensor Interface Module (SIM)
Position the SIM in a dry, protected area where
the ambient air temperature does not exceed
167° F (75° C).
Fasten securely.

Can you use the SIM module with I-command Digital instrument?
Or does it have fuel level calculations builtin, like seasonal fuel?

I called b.r.p. and spoke with Al and he said yes you can mount it on motor or in console. I sure hope it works with digital gauges because that's all I'm using. He also said that both ends of wiring harness are the same.

What can be mount on motor or in console?

If you talking about the SIM module it use a 6 pol. female as should be connected to the power hub or consolidator hub.

Or do you use a lowrance cables, they have a plug that's gray and blue?

Yes , I think that's were the confusion is. I'm using lowrance cabling. It is so much easier and cleaner to use than the buss system with all the hubs and consolidators , it's just simpler, cleaner, cheaper. You'll also notice soon that even b.r.p. is going to get away from their system and just use lowrance . As you already know that lowrance lmf gauges are the exact same as I -Command . No need for all the extra stuff .

The sim is a device intented to covert "Vessal" information specifically fuel tank level, from an analog signal to a digital signal. It does not interface at all with the engine. It talks to the network wtih information about fuel level and then to the Tachometer/s. Seahorse is correct it works only with the Classic style.

With I-Command you need to remember "talkers" and "Listeners" Some of the talkers are devices that send information on the network. Some devices are vessal realted info and other are engine related info. The engine is a talker, it sends infomation to the network. The Gauges are Listener's and they interperate the information and display it.
The SIM is strictly fuel related. Thje speedo will combine multiple engines into a combined vessel consumption rate but the SIM is what does the storage of fuel burned information.

I don't get it ,when I spoke with tech guy at b.r.p. , by the way he works with I-command software . He stated that was what I needed to get the fuel burn directly from fuel injectors

I-Command Digital User's Guide
page 24
Fuel Manager:
NOTE: Fuel management requires a fuel memory module.
See an authorized Dealer for accessories.

you do get the fuel burn directly from the injectors. But how does that data get translated into something we understand? That is the job of the Tachometer. The Tach is a microprocessor and it process's the data from the engine and displays it.

The engine is sending out raw data in the form of injector pulses and the Tachometer does the mathmatics to convert those pulses to the GPH display - .18 gph, 2.0 gph etc. Remember "talkers and listners" The engine talks and the Tach listens, interpretes and displays the information.

For Sale : Two simm modules for I-command classic gauges !

I'm pretty sure you just need the EP-50 storage device Mako.

I've got one and fuel management from the EMMs works just fine. http://xs-s.com/zf/images/smile/emthup.gif
