So it's safe to bridge them together? Have you ever tested your system somehow? I've heard that tapping the block with a hammer should trigger the knock sensors.

i know they work... my meth quit working once and it went to the yellow before i relized and let out. they are not bridged to the ecu, althought that wouldn't matter either b/c the ecu dosen't care if the knock is on the front or rear 3 cylinders it sees any voltage from either sensor and it pulls timing.

Cool! So you have one knock wire running from your add-on module connected to the + wires of both OEM knock sensors, tapped in before the ECU?
