Hi guys,

I'm just in the process of trimming the excess and adding a few bits to my gt4s loom.

I've added the additional COP loom and just remembered that I've got a 2 pin Bosch knock to go in in have the shielded wire for it and understand that the sheild needs to be connected to earth at 1 end, I'm replacing the stock single wire sensor so just need to know what the pins are on the new 2 wire one so I can get it all in and sorted.

My ecu is a link g4+ plug in btw

The one wire goes to your ECU knock dedicated pin and the other wire with the shield twisted goes to sensor GND pin.

Cheers

Here's the schematic from Link/Vipec.

Cheers!
