Hi their, I'm having some stupid issues with my new viper system, as soon as I connect the battery my car instantly wants to start and when it does the starter keeps cranking, I pulled the fuses on the 12 volt constant leads and connected the battery, and when I replace 1 fuse its all good but the other 12 volt constant lead turns my radio on, fuel pump, and starter. My car is a 95 t-bird, 4.6 LX. Can someone please helpme out. I've hooked up the tachometer and the only thing I can assume is the turn off switch but that should be to simple.

have you tried turning off or disarming the alarm after you hook up the power wire?

If I grounded the neutral safety switch, would it cause this to happen

is there a wire on the unit that is ude for - input that will send the unit into remote start mode?????

some units have a wire that if it sees a neg ground, it will go into remote start.....double check all your wires or post the diagram and how you have them hooked up.....

are you talking about connecting the main battery cable under the hood and it cranks? or you hit remote start and it cranks? most of the time you connect the small BLACK/ white to the toggle switch and ground it. turn the switch off and connect the battery, then turn the switch back on. will it remote start normally after that? if it tries to crank right away you have an ignition output hooked up to the starter wire.

yeah, I grounded the toggle switch and I've turned it off but she still wants to crank. My book says that purple is the starter crank wire and that green is the anti-grind. I disconnected the crank wire and hooked up power to the modules and as soon as I did that purple wire starts getting 12 volts. I'll go double check that harness though and see what I get.

Ok I just went andouble checked that my crank wire is purple,however a problem that I wasn't even paying attention to,is that my + Ignition out wire(PINK) is reading 12 volts aswell and so is my +Accesory output wire.(Orange) However my +Second Ignition wire,(Pink/White) which I'm not using is reading 0.00V as well as my Anti-grind(green).

They're all grounded real good at the driverside kick panel. I went and swapped the the brain modular system, and I get the same thing. I tested the on/off switch and its workin good. I'm going to maybe just rip it all out and start all over again. I'm really appreciating all the suggestions though.

the white blue SHOULD NOT BE GROUNDED to anything.

make sure none of the wires that feed the relay back are shorted out, also if you've plugged in the 4 pin aux harness into the relay pack, make sure none of thos wires are grounded either as they will activate the onboard relays.
