This will blow you're mind...
My boost gauge's illumination has been on the blink for about a month now. it's a 7 colour one that changes with the push of the button on the front. now and then it would switch from blue to nothing and be simpley set back to blue with the button, but after I installed the voltage gauge they would both be set to blue and then for no reason switch themselves to pink. I removed the voltage gauge and now the boost only lights up red. ok so time to investigate. I decided I'd wire the main power straight into the fuse box using the strip of power that runs down the side on the back. Apon removal I found this...

would anyone like to guess where this wire goes to and it's job? Well to save you pondering on that one here's the answer. it's the power wire for the ECU! The relay has been removed and the wire pushed in there and the relay replaced. Forgive me if I'm wrong, but doesn't that wire rate pretty high in the most important wires in the car?
What's more it isnt' even a new wire! It joins twice before reaching the ECU, each join wrapped in electrical tape! You've seen the mess Designa Dubs left my car on their first install. This is there on their 2nd attempt! You would of thought they would of made extra effort on this engine to nurse the damage from their first f**k up!
