Instructions for knock sensor cable:
To make your installation easier, we have pre-installed the knock sensor connector.
1) Install the knock sensor.
2) Connect the sensor cable.
3) Feed the other end of the cable through the firewall.
4) After determining where the SafeGuard will be mounted, route the cable to the SafeGuard.
5) Insert the Red wire of the knock sensor cable into the pin labeled “Knk”.
6) Insert the Black wire of the knock sensor cable into the adjacent pin, labeled “Gnd”.
7) If you wish to shorten the cable, cut to length, strip the jacket back about 1.5”. Before discarding
the cut end, inspect the solder joint under the heat shrink. You will see that the shield is connected
to Black. Use this a a guide to prep the cable after shortening. Solder and cover with heat shrink.
