here is a video of it starting up with BCM connected,Dylan wrote:Maybe you need to ground an input for some door switches? Such as bonnet or boot or door switches. The cluster will alert you when the alarm has been previously activated and even which door or boot was opened. Something to check off anyway.
looking through the BCM PDF i have all the doors switches are earthed when open, so being open circuit they wont be pulling low so BCM should think the doors are shut.
It could be that when the BCM and cluster power up it goes straight to ON (both ON and Ignition and BCM main power are triggered together.
The cluster did come up as "hotwired" on a few startups haha.
Please excuse my wife in the background,
