Today the 7-pin DIN plug & socket arrived, and so all cables could be tied down.

The gauge 'display' will be able to be unplugged from the car..

Refreshingly, DIN plugs are able to pass through the rear of the ashtray, through existing square holes!

All that remains to be connected now, (other than the senders themselves), are the feeds from the ashtray-light, which provide the backlighting and negative reference for the gauges. I need to think of something clever for this, as I don't want to just 'chop' the wires...

Thank you guys,

That's very kind!


As it happens- I worked out a way to get the backlight & negative reference off the ashtray light cabling;

I stuffed them into the back of the connector! No harm done / lines cable tied into position, no problemo. I pulled out the now redundant lamp itself.

okay!

Well, after a significant delay; where the bodywork (that I could do myself), and stereo took over, (plus the winter of course!)- I have come back to this...

This week, I pulled new lines for the sensors between the cabin and engine, as I started to think the original wires I pulled had been compromised. (It didn't work) I also spent a lot of time with the oil-gauges binnacle on-the-desk, measuring how it responded to different resistances.
In short- it's going to work!

Then I spent most of a day straightening out the metalwork; which was still quite rough from last year.

Using an infrared thermometer, I was delighted to see that, following an engine start and about 10 minutes idling, a measured '80 degrees' at sump was reflected by the gauge!!

following the rip-roaring success of this little triumph, I went further to establish that the instrument backlighting in the oil-gauge binnacle wasn't compromising the measured resistance at the gauge-coils. I felt it might be last year.

However- It wasn't. So, unhappy with the quality of light I was getting off four of the midget backlight-lamps, I set about making a low-power LED versions to light the binnacle with...

then, onwards into the cosmetics.

Sometimes you get lucky if you do enough prep, and heat the part up enough, before rattle can spraying...

Then I made side-cheeks for the thing, and painted them too, and confirmed final fit within the ashtray, on the desk...

'Q' would be proud of that!

Great work mate. Love the alloy fabrication. You done great job there. Top job!! Bet you can't wait for the lighting up day. Have you got all your sensors for the pressure and temp?

Sorry Ganz!

Only just saw this too!

As it happens; lighting-up day has been and gone, although I'm not quite as happy as I could be with it- the needles are just 'needles', as opposed the illuminated pointers like in the standard instrumentation. Plus they aren't orange- yet...

see attached images (ignore the muck about external temp 'gauge' in the fag-socket- it is NOT permanent!)

The pressure sender has just gone into the block yesterday, using all the ridiculous adaptors i got. I am actually expecting an adaptor from Desperado through the post, but it is yet to arrive.

I CANNOT get it tight enough to stop a residual weep of oil- how much of a weep would people be prepared to accept as still 'successful', I wonder..?

Just about to drive the car up North on holiday tomorrow, so I'll have to keep an eye on it. It's not like these cars are turbocharged (sorry JasonHillAO), so it should be okay...(?!)

(sorry- this last picture has come out upside down)

quick update-

I realised last night that I hadn't actually tightened significantly, the oil-pressure sender itself, into the first adaptor.

I managed nearly a full turn!

200 miles later; this afternoon... See attached: bone dry... Result..

incidentally-

Does anybody think this is 'too close' the the block..?

Heat wise I mean?

The right angle adaptor gets the pressure sender to clear the block casing 'just'- it is NOT touching, but very close.
Do you think this will mean the sender will get too hot, over time, to work effectively; or will it be designed to take it...?

It will be fine like that.

You were brave giving it an extra turn! Its one of those things you need a feel for. [which youve obviously got]

'brave'- ha!

Well, I've worked 'with my hands' on-the-tools, for twenty five years, so I'd 'like to think' I'd know when too much was enough, if you see what I mean.

Plus the secret is actually using small tools, at such a moment, rather than enormous spanners, which couldn't fit in anyway, as you can really feel the torque being applied.

But it was a tense moment none the less! I've certainly learned a bit about hydraulic tightness from it- and it's still not leaked.

Thanks for your feedback Desperado- I've replied to your PM
