Ok, at last I have fitted these to my Stack dash and have them working.
Like a lot of things, it is a easy job when you know how. And should take a maximum of 1 hour to do.
So to start.
1, To make the job easer, take the Stack dash out of the dashboard.
To do this, feel under it and locate the main wiring connector. This has a round locking ring around it, so turn it anti clockwise about a quarter of a turn and it should just pull off.
Now you should also be able to feel 4 nuts (5.5mm) undo these and remove the brackets (look out for the tiny washers) 😳. Then you should be able to push the Stack out of the dashboard, towards you.
2, You should now be able to see the main wiring loom for the Stack (to the left hand side of the hole), I had to cut a few cable ties to be able to fan out the wires.
You are looking for 3 wires, black (there are about 3 of these), for the earth.
Green (quite a thin wire), which is the live feed.
And a white wire, with a black stripe (this is the tacho feed).
3, Connect the Black wire on the loom, to the Blue wire on the DRE.
The Green wire on the loom, to the Red wire on the DRE.
Then the White wire(with a black stripe)on the loom, to the Green wire on the DRE.
Job done, it really is that easy. 😬
I have a 1.8VVC and have set the Low point at 4000rpm, and the high point to 6750.
Have fun.
