Tachometer wiring - MY82 RHD

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

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.

[macplaxton]

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.
