NMEA-2000: Installing I-COMMAND Wiring Harness to Motor

All: I have an E-TEC outboard motor almost installed and almost ready. For the [I-Command NMEA-2000 digital instrumentation's] wiring harness, [the instructions] says to "connect the purple wire to the power supply red wire." I can't find the power supply red wire, at least not one that is free and has a push connector?
Do I need to strip the connector and replace it with a ring connector and connect to the engine? Is the power supply wire just tucked in somewhere and I can't see it?
Thanks for any help.

Did you install the I-Command harness from the motor to the keyswitch like the directions tell you? If so, the bullet connector and purple wire are there at the motor.
If you still have the original wiring harness, there is no wiring for the I-Command and the trim will not read on the display screen.
See your dealer for the correct wiring harness.

I installed the PN 763544 which is the Ignition Tilt and Trim harness. The harness has a purple wire on the engine side, which the instructions say "connect to power supply red wire". What red wire? There is no red wire, loose on the outboard with a bullet connector? It's the red wire, I am looking for?

OK, list the part numbers and descriptions of what you have now to install the I-Command system, ans what instructional booklets do you have?

List of Parts
PN 763544 Ignition Tilt and Trim Harness
PN 763510 15 Ft Extension cable
PN 763678 Network Power Supply kit.
I-Command Install Guide
I have run the Tilt and Trim Harness from the console to the engine and pluged in The outboard Trim/Tilt connector and the Outboard Ignition Connector as shown on page 8, Single Engine installation. On the engine side, same page it shows switched B+ to Power Supply Harness Red Wire. I assume the switches B+ is the purple wire for switched power but I have no other power supply harness or loose wires to hook it too. The Network Power Supply kit, goes at the console end to power the network and hooks to the Purple & Black wires.

Pics of mine emailed to ya a little while ago.
I'm reluctant to cut the wire ties for a better look see but if ya can't make it out in the four pics, let me know.

I have a better idea. In the 175 they have a bundle of wires in a black plastic tube. I believe that I will need to look in that wire bundle some more. Here is a shot of mine before I started rigging,
Someplace in the tube to the forward side of the engine should be the wire. I pulled the cover off as I ran the wire harness up thru there but I did not unbundle all the wires.
If anyone knows which bundle of wires it's in, even better and is it a purple wire or a red one? I assume it's the only one with the bullet type connector.

Here is a cut-and-paste from the I-Command Digital installation guide using the Lowrance style wiring components.
You can connect the power harness to the key switch at the dash or at the motor using the purple lead.
Your list does not look complete. Refer to the part numbers in the following guide.
STEP 1 – Connect:

Do I need to connect the purple wire of the 763544 Ignition / Tilt Adapter Harness to the outboard and if so where?
I have already done Step 1 and Step 2 on your list. I skipped Step 3 because I am not installing a fuel level sensor at this point. I have also done Step 4 and 5.
The part that is not on your list is connecting the Ignition / Tilt Adapter Harness to the engine it self. I have all of that done at the engine side, but the purple accessory wire is not hooked to anything. That is the wire I need to find a home for?

We might be trying to achieve the same result see: http://continuouswave.com/ubb/Forum6/HTML/001411.html
Do you have pics of the I-COMMAND harness on the helm side? In my case I think the system needs to be powered up from the helm side maybe yours does too?

Simple question, the tilt and trim harness has a purple wire on the engine side. Do I plug that wire in and if the answer is yes. Where?

The purple wire on the engine side of the harness plugs into the older style I-Command wiring that used the consolidator units as a wiring buss. That purple wire which came off the keyswitch A terminal fired up the network when the key was turned to ON.
On the Lowrance type wiring, most folks use the 763529 power harness under the dash and attach the red wire to a purple and black to ground to fire up the network.

My to do list is getting shorter,
All the e-tec connections are done except to hook up the oil and gas and go crazy with some zip-ties. Once I bundle all the wires in the console and screw it to the floor, its off to the dealer for checkout on friday
I may have to spend some time in West Marine parking lot, trying hub kits otherwise its a basic aluminum prop and on the water by Sunday :)

Is it on the water yet?

yes she is. The boat was on the water as of Saturday morning and by late afternoon, the engine hour meter showed over 7 hours. I will post more photo's as soon as I finish some little things but here is a before / after shot along with a video
