Itl work but the display won't show you oil level (presuming its autolube).

If I'm honest... It's a bit rich too. If you can hold off you will be able to pick one up a lot cheaper.

Il have a dig about in my spares and see what I have lying about.

I've got the trim harness here and I've sent a txt to a pal that thinks he has a brand new 2/ gauge, he's going to get back to me. He's away for a couple of days.

Il be in touch.

Ah wow that's great so possibly the guage is the same?

A1an · 19 December 2013, 21:28

It's possible that its the same but they are all the same size and use the same wiring anyway.

Gramas · 19 December 2013, 21:28

Trim only harness as there's looms out back of mine with plugs on or is it all one harness?

A1an · 19 December 2013, 21:33

Itl be a two harness unit, one is for trim and one is for power and tach.

Gramas · 19 December 2013, 21:39

Graham, the T&T harness I have will fit.

You will also need another loom that connects the other wires to your 703.

I'm lost then graham, I've only ever seen the flat harness going from tacho to engine.

Gramas · 27 December 2013, 23:03

Will check May be me not seeing things right but let me know want u want for it as more than likely it's what's required

Correct me if I'm wrong but after playing around with one of these a bit I seem to remember that there is an 8 volt (ish) feed from the tacho that goes down the extra flat loom to the trim sender on the engine and then back up to the multi function gauge ??
The extra loom is all for the trim gauge part of the tacho head ??
