I was just wondering if anybody had fitted one onto zetec?

If so where about?

I have one coming from canada that works with megasquirt, dead cheap I thought at about £60 including interface, knock sensor(used), postage and a optional extra heat resistant cable.

Anyway I have bought one but have no idea where or how to fit it. I don't really have much room on the intake side so will probably need to be exhaust side.

generally they are usually fitted direct to the block somewhere near the middle up high fairly close to the combustion chamber area.
Knock as in pre detonation of mixture in cylinders.
