Mark (MCHUDD) might be able to shed some light on this, seen as he's fitted one before


Tachometer Accessory by macplaxton, on Flickr

So, I've got this tachometer and it comes with a mini-loom with 3 wires and a couple of Scotchloks (bag at right of photo).

The +ve and -ve are easy enough to deal with, it's the pulse wire to the coil that is the problem. The wire is too bloody short! (LHD?)

As far as I can tell the coil has lived in a number of places before MY84, when the Renix came in.

MY77 - side of block? (Sion?)
MY78 - left top corner of bulkhead
MY79 - left top corner of bulkhead
MY80 - left top corner of bulkhead
MY81 - left top corner of bulkhead
MY82 - front panel to left of radiator (you can see where the red wire goes to the right of the picture)

Is this the same for LHD? (Send your answers/pictures this way and I'll add them to the post.)

Either way, it's a bit of a pain to reach from a RHD. The loom seems to suit a LHD car with the bulkhead coil in front of the instrument panel. For me though, they couldn't have put it further away!

I've also had to use the front from a earlier panel as MY82 panels have two holes in the lens as they come with a front adjust clock.

Hi mate.
I will try and find the intructions as i still have them somewhere in my cave
Cheers Mark.

I've got the instructions. It's just the supplier wiring seems to be cut to length for MY79-MY81 LHD.

Cheers for the PM.

Hi mate.
Are you showing off with that mileage reading?

Cheers Mark.

Aye.

Handy pic from my Flickr account showing the two holes. That must have been taken on honeymoon on the Isle of Wight as it only had 14267 when I got it.

I've also got a pic of the dizzler dash somewhere with 245K miles on it.

Yes, the coil is indeed on the block for MY76 and 77, although I believe that they moved it up to the n/s bulkhead later in the 77 model year due to overheating issues. RJ is likely to be able to give an accurate chassis number for the change.
