I have a 2000 Jeep Wrangler that I have installed a 791XV, Back Up Battery, Piezo Siren, Shock Sensor and Proximity Sensor on. When I installed the proximity sensor, I spliced the connector for the shock sensor in with it (red, black and blue from shock sensor to the red, black, and blue from the prox and then plug that harness into the brain) Now everything works just fine, however both the proximity sensor and the shock sensor cause my LCD remote to display "Sensor 1". I am wondering, just how you would hook a proximity sensor up to display "Sensor 2" while the shock sensor would still display "Sensor 1"?

The trigger wires for the prox sensor whould have to be hooked to the green wire that's free on the shock sensor harness. That wire causes the brain to report sensor 2.

So instead of hooking the blue from the prox to the blue from the shock, and the green to the green, I should have hooked both the blue and the green from the prox to the green on the shock sensor?

the blue from the alarm goes to the green and blue of the shock sensor. It will report as zone 1
the green from the alarm goes to the green and blue of the proximity sensor. It will report as zone 2

The sensors give off a short pulse for a warning, and a longer pulse for a full trigger. The alarm brain can determine from the length of the pulse it receives if it should give off warning chirps, or fully go off with the siren blaring.
