Rev Counter

[douglasblack5]

Hi all, didn't fancy paying £60/70 for a used rev counter for my 2005 Aygo, so bought a Vauxhall Agila one for £10, all fitted, working and doesn't look out of place. Unfortunately can't get the illumination light to work, only when side/headlights are off, soon as I switch sidelights on rev counter light goes out.  The Agila has 5 wires compared to Aygo's 4. Anyone have anyideas please.

Thanks

Dougie

Good mod that. Been thinking abut one for daughters car. Did it come with the pod too?

You have taped the wrong lighting wire or the rev counter uses a negative for the lighting

i will pull up a diagram for the Agila in the GM GDS

How have you wired in the tacho ? using the factory plug ?

Had to cut a 1" x 4/5" slot, not noticable. Had to remove silver pod bezel to get pod in and then clip in.

Agila plug has 5 wires, Aygo 4, had to cut both and fit new 4 pin plug.

Would appreciate that, Agila has 5 wires compared to Aygo's 4, cut both and fitted new 4 pin plug. Tried every permutation but can only get illumination on when lights are off ??  Illumination goes off once I switch side/headlamps on.

Not had much luck tracking the info down for the Agila

I will have another look later today and work out what's going on

 

The Aygo has a Switch live, illumination, Ground and Tach

I haven't forgotten, I'm having few issues with the gm software, in the process of putting it on a virtual machine it's a pita but its something to do i suppose

The Agila was built by Suzuki in Hungary - first generation a rebadged Suzuki Wagon R and the second generation a rebadged Suzuki Splash. So perhaps a Suzuki database may throw up something ....

i have been down that route the other day, information is thin on the ground, i have most gm info up to 2004 and some models 2009-2019 but not the Agila B i did have TIS access but that's now lapsed

I have owned a few Vauxhall's and have work and driven many more over the years

[flash22]

After many hours and then remembering its in German i have the info it shows 4 wires

pin 1 - White/Red - Battery positive

Pin 2 - Brown - Rpm Signal

Pin 3  - Black/Orange - Ground

Pin 4 - Red/Yellow - LED dimming signal (dimmung-signal)

 

Im still looking to see how the dimming works (slow process translating from German) on the Agila, from what i can gather the Aygo uses a positive switch lighting

 

if you ground the Red/Yellow it should give you lighting, If so that should be simple to sort out
