Vettech:
Another question.

Accelerator pedal has the spring loaded foot pad, but the whole pedal is pivoted further up where it bolts to the firewall.
Is there a spring meant to be in there ?, otherwise its just the weight of the lower half of the pedal that pulls the cable centre back.

Not sure I have this well thought out, but I know there is a heap of travel in the pedal before it even starts to pull the cable and start accelerating. And since we all know just how powerfull these little C4 babies really are, I feel I'm not getting maximin bang for my buck.

And yes you guessed it, the pedal is out of the car.
(Pedal also needs some metal removed as its interfering with other bits.)

If the distance between the firewall and pedal isn't correct you will end up with slack before throttle starts to open you can slit a small piece of metal tube length wise and slip onto cable between ball end and pedal then close up with pliers, to make more responsive. I had a new cable made for RHD and had an adjuster put in cable between bracket and throttle body arm. If you change the pin on throttle body to a ball stud a holden HJ about 1300mm long will fit and is available on ebay.You also need to adjust TPS to get max voltage at wide open throttle,then adjust the auto kick down cable to suit, kick down will prevent WOT if not adjusted correctly. Cable pulls back from throttle body no spring on pedal

Yep its not Vats, today I modified some towel rail approx 40mm long, some black Silastic,  and my last piece of ducting is jointed up very nicely, whilst checking, the car would not start, bloody hell what now, and a plug kept poking into my eye...... Ah! Plugged it back together, and after a wait car started, well at least Vats and the key resister etc are working Ok. (Its a very small 2 wire plug/socket).
Not the one I'm chasing though.

Started to rain again,  anyway the Silastic needs to set, save more for tomorrow, when I'll try the Instrument panel back into place, test for any issues, there are days stuck up under dashes that I wish I had the statue of a small brick laying person, they get it so easy!..
Regards.
P.S. have not re-installed the Pedal as one bolt is cross threaded, I wish Bunnings was open, although they dont sell individual dies or taps for that matter, maybe I'll sneak down to see the Wilton Oracle. Get my black balaclava on and run Blockades.

Oh and ........ "Goodbye  Glady's".... I'll miss you at the morning Covid19 updates (LOL)

Gladys for PM.
Bfit
Ps a year and a bit to next federal election, timeframe’s about right.

Vettech:
A Glady's one day, a Barilaro the next - we go thru Pollies like a dose of salts.

Anyway. Put the Instrument Cluster (IC) back in place along with enough other bits to allow power up and test.

Alas Grasshopper, we still have issues, the IC is a "plug in" arrangement (see below) the plug is set thru the main PCB, those little silver spots are the ends of the pins and plug into the socket which is captive in the base of the IC cradle. But the socket is proud of the back plane and SHOULD plug right thru the PCB, one glance at the arrangement smacks of potential problems. Once in, all systems came on, but whilst securing, lights etc started to flicker on and off, any pressure on the IC diametrically above the plug gave varying results, also any pressure up under the rear of the cradle behind the wires going to the socket also gave varying results.
I can only hope that its not the wires, but the plug socket not mating correctly, it definitely does NOT have that solid plug into socket feel that I believe it should have.
Other than the swaping from LH to the RH side of the dash, the cradle has no modifications that I can see, but it may be warped enough to allow the pins at one end to be not correctly seated. But! After perusal of the connector cct/pin layout, I feel that unless we have one earth or power wire crook, then it is an overall plug/socket seating issue. AND.... requires the IC to be removed again, if only I had a new clean plug that I could set up up to test every cct. If only.
