hi all, i have bought a detalarm from roojai on ebay and this doesnt come with any sensors could anyone tell me where the cheapest place to get the bosch sensor and lead to connect it if one is required.

 

Hi there i brought a detalarm and got my knock sensor from the scrap yard off a vauxhall astra think all vauxhalls are the same cost £2 its on the back of the engine block by the pistons you need the cable that goes with it to hope this helps
