SmartCraft Setup

[got_musky]

Greetings,

I just got a new to me 2007 TR 21 X HP Triton. It came with some wiring harnesses, smartcraft gauge, junction box, etc. that were new in the bags and never hooked. I've tried looking for a quick guide to getting this gauge hooked up directly to the motor since I don't really have any intentions at this time to hook up any NMEA devices/to my humminbird. I am trying to understand if it is all compatible/what I actually need to connect in these wiring harnesses for my motor.

Motor S# is 1B445539

Items that came with:
- SmartCraft Gauge: Mercury No: 8M0043420, VDO No: A2C53388608
- Harness ASSY (blue cable): P# 84-879982T20 (appears to have termination resistors on both ends)
- Junction Box: P# 878492K14
- Harness MNT PWR ADPTR: P#84 879346T56 (is this power for NMEA network so I could hook up to a NMEA compatible H-Bird if I wanted?)

The thing that seems odd to me is that the SmartCraft takes a 14 pin connector, but the rest of the mercury connections take 10 pin connectors (motor, j-box, etc.)

It also appears that the blue cable has termination resistors on each end. Do I need the cable with only the termination resistor on one end (motor side) in order to use this setup with the junction box? And, additionally, would I just need the male-male adapter in order to use the existing blue cable direct to the gauge?

Thanks in advance

Chris

Lot of info right at the top of the page on the Mercury forum.

Thank you

I read through that thread a few times actually before posting. I am pretty good with electrical wiring and such but what is difficult for me right now is that I have a box full of parts which came with the boat and I feel like I am missing something. What I cannot find/am trying to confirm is that if I have ab and c, I really need d, and not c. Or since I have ab and c, I could get e to replace a and use bc and e.

That said, I feel like I can get the male - male adapter (P# 892452T01) to make it work: blue cable (terminating resistor on each end > male to male adapter > harness to mercmonitor)

Just looking for confirmation before running off and throwing money at different cables/parts to try and make it work.

UPDATE:

I got the male/male connector. No change. With the blue cable (motor end) hooked up to the motor, other end to the m-m adapter, and then from m-m adapter to the harness for the mercmonitor, I turn the key to on (not starting the motor) the gauge does not turn on.

I'm sure the answer is staring me right in the face.....what am I missing?

Some pictures of the gauge and where you have it connected at the motor would help.

Here we are

The last picture shows it all hooked up. Brought it out just like that, hooked it up to the motor (after removing the yellow termination cap from the motor connection) and then turned key in ignition to on (but didnt start motor).

Nevermind - I figured it out. Minor detail: need to connect the vessel ground

Yes, you do!

BTW... the number you provided for the instrument isn't a valid part number. Likely something from the gauge itself... which we've still not identified (your google drive link requires login to see it).

Thanks Don, hope everyone had a safe 4th of July! I put it back to private since I had figured it out. I believe the gauge reads V5.0 when it starts up.

I took the boat out for the first time last Thursday, so far had an issue with the starting battery not holding charge and throwing wild alarms I think due to low voltage (I've replaced that now and no more alarms) and now what appears to be a leaking tilt seal around the rod. Will start a new thread for that

For what its worth, here's a pic of the back of the gauge.

Version 5.0 MercMonitor, meaning it's a Level 1, 2 or 3 (with NMEA-2K Gateway). Roughly mid-2010 production.
