Got it sorted already... FYI the sensors downstream of the connector do not have the same wire color as those upstream of the connector...

Have fun with your project... I'm in a similar process this weekend since the wife is out of town...

Have you ever heard of dampening the knock sensors ?... That's in the works as well... The process requires adding a spacer / damper to the attachment points ...

Removed the AC pump and ran a new drive belt and it clears the other pulleys without a problem... So, I just got rid of 6.8 kilos of useless weight without having to install a dead pulley...

Cheers... Gotta get back to the garage...
