6 bolt swap knock sensor wire connection

[lazyazzdaddy]

I have a 95 talon tsi with a 6 bolt swap, with a 95ecu useing dsm link I reciently had to chang the clutch and when i had it on the lift i noticed that there seem to be two knock sensors on my motor, one on the head and one on the block.. the bottom one is connected to the ecu.. to me it would seem that the top one should be connected but thats just me, I've only been doing this for a short time so i fugured i would ask some of the more seasoned guys on here what there take on this is..
thanks in advance for any help.

You only have one knock sensor, and it is threaded into the back of the block. The sensor on the head has to be something else. Post some pics!

Alright,ya that makes more sense to me...I did'nt think there were two.. so it must be hooked up correctly seeing as i am getting knock readings with dsm link. now i guess the question is what is the other sensor and should it be connected to something. when i get down to the shop today I'll take a picture of it.. Thanks!
