Airsoft wires

[pdansalvish]

I found a new airsoft on Ebay and have it installed in my tank. The Airsoft has two sets of wires. Once set is yellow/yellow and the other set is yellow/red. Does anyone know which pair is for BB?.

The set that goes to the small motor is the set that fires the BB, the other set goes to the "trigger" switch that operates the recoil feature and the gun sound.
