Possible Earth Issue

Hi guys
I'm having an issue with my HK I suspect is as earthing issue.

My lights and tail light lamps work.
My brake lights work.

However, when my headlights are on, and I put my foot on the break, my driver's side rear lamp turns off.

I've heard HK holdens are infamous for bad earthing, so I'm curious to hear people's thoughts.

Inside HEI module

Thought I'd pull this apart while I had a few minutes, would appear the IC is toast. This is a generic module, not Bosch. Would be interesting to compare.

HEI module tech

Does any body electrically minded have a diagram of the internals of the HEI module? It's only a curiosity as I've seen a number of these fail and every time it's due to poor earthing of the module to the engine block/chassis. I'm curious as to the path of failure caused by the poor earth.

electrical issue with indicators

HI, can I please get some opinions on my electrical problem.
I hope its just a cactus indicator can (which I cant find with a quick search)
one green indicator stays on, on my dash, and both rear indicators stay on.
this is when I have turned off and taken key out.
if I move the indicator stick it turns one or the other rear light off.
does it sound like a real problem or just look harder for the can and replace it?

WB to HZ GTS Wiring Mods

I have removed the WB DeVille dash pad and all gauges & instruments from my HX 1 Tonner and have an HZ GTS one to install. The GTS gauge panel is all 'pre' wired with a loom plug on the end. However, the WB DeVille loom in the car has all separate wires running to each gauge.What is the best way to integrate the GTS dash panel in with the WB loom? Should I just pull out the wiring behind the GTS instrument panel and plug in the relevant DeVille wires, or is it not that simple? Lastly, the DeVille had a clock, but no Tacho. Is it just easier to wire in the tacho separately?

GTS dash wiring

I've got a HQ premier and in the process of putting a GTS dash into it.The car came with GTS clock already in the dash,my question is can you put a GTS dash in using the standard wiring loom as I have been unable to get a GTS wiring loom.I have all the gauges and was wondering if you can cut the oil warning light wire,the temperature warning light wire which come on in the standard fuel gauge and put electrical connectors and plug them into the back of the gauges.I am happy to run independent wires for the tachometer but I want to try and utilise the existing loom if possible.Any advice wou

I've wired it all up except one wire. it's a pink/tan looking wire and its in the same loom plastic for the anti dieseling solenoid but im not sure where exactly it would go. i know its for instrument lights and fuel/temp gauge on the dash because i thought it hooked up to the starter motor and when i did that it iluminated all the dash dummy lights even with no key in the ignition. any help would be amazing
