SMG4 Mech Install Guide

[@fishski941]

I guess Suzuki just conveniently left out of the installation guide the part about switching plugs at the ECM. I was scratching my head trying to figure out why the unit wouldn’t power up. If it weren’t for this video, I’d be trying to return a defective unit. Kind of a key bit of info. Thanks Precision Marine for the video and great prices/customer service.

You saved me a BUNCH of time. Would have never figured out switching the plugs. Thank you sir

[@allycat1521]

Thx!

Does you manual trim on your shifter and motor still work ? Will my fish finder gauge still work? What does the 2000 end up doing when you plug it into the smg4 to the existing data readings ?

[@surferdad]

Thank You

Will my 2012 harness have the correct plugs? The motor is a 2023 and they just plugged it into the old harness. Trying to switch from analog gauges.

I have a Raymarine axiom 9 and SMG4. If I use the Suzuki interface cable with the SMG4 and my axiom, will the SMG4 still operate?

[@christopherey7142]

Does anyone know of instructions for setting the initial settings on the SMG4? My LCD died and I need to swap in a new unit. The owners manual only says those settings are for your dealer. 🤔

[@nickrdgz9323]

How do you install a Suzuki interface wire to that unit?

[@MrElsapo33015]

Would this work on older engines, 2008 suzuki 175 analog?

New boat came with this. But it reads check gauge c and if plugged into grey port stays on and won’t shut off.

[@alasdairmacfadyen1532]

Did you get a fix ?

[@ZethKinnettFishing]

@@alasdairmacfadyen1532 yeah but it was a pain. I posted that over a year ago. Gauge was determined to be bad along with improper wiring.

[@Eyball1972]

Mine lasted a whopping 2.5 years now I need to spend another $500, thanks Suzuki.

[@TheHonro]

Should be under warranty.. Suzi now has 7yrs warranty

[@Eyball1972]

Not on rigging or accessories. I checked with my authorized dealer, 12 months. Luckily I found a replacement on eBay for a discount. 😕

[@vikingone9852]

Just bought one and it it didn’t come with the harness? Do I have to buy it separately?

[@azoressubruicabraldemelo4480]

Yes

[@arikhancock]

I did the install like show but my gauge reads (check gauge c) and I see no data on my smg4.

[@ZethKinnettFishing]

You ever figure it out? Mine says same thing and won’t power off when using the grey port. 2023 DF250SS

[@bahamaboy1089]

​@@ZethKinnettFishing Where was the digital harness plug on your motor? I can't find the plug to switch on my 250 Suzuki

[@ZethKinnettFishing]

@@bahamaboy1089 its tucked back behind shit in the fuse box. gotta pop the cap off and look around for a grey port

[@dustindudoit647]

will this gauge work with twin 2012 df140's ?
