external acc switch to bypass using key

Hello everyone i am looking in trying to hook up a switch so that i can roll my windows up/down without having to put the key into the ignition and turn it to "ACC/ON" mode in order to do so. Could someone share their knowledge with me on how to go about doing something like this? Thanks! :) David

can you tell us what vehicle you want to do this to?

Sure. A 1992 Dodge Stealth R/T Twin Turbo. I already know what wires there are for the ACC/IGN and so on, i just need to know what all needs to be hooked up to a switch in order for me to be able to use that instead of my key to be placed in the ACC or "on" position. Thanks, David

with a fused lead, connect a wire from 12v conatant into one side of a toggle or rocker switch. connect the other side of the switch to the acc wire in the ignition harness. thats it.

Wow ckeeler, really? That's all that i would have to do?? What would i need to do in order to start it then if i have that switch plus a push button switch to start it? David

then... you also would need another switch to trigger a couple of relays(one for each ignition wire) that would power the ignition wires. then when you pushed your start button you'd be running. use 10ga or 12ga wire to do these circuits. also use 10ga or 12ga for the toggle you wanted to use for the acc on to roll up your windows. unless you disable you steering lock though, you still need a key anyway. and if you did disable the lock, without a security system, or RFID system, anybody could just break a window, flip the switches, push the start button and drive away. just something you might consider.

Here is the schema for my car... Could u let me know if this is what you are talking about? ---fuse--12v--->|Switch|<---acc wire--- ---relay1--|    |-->--Ign wire--->|Switch|<---?? Ground? ---relay2--|

wire the ignition relays as follows: 12v from the white wire in the ignition harness into the rocker switch, out of the switch to term 86 of 1st relay for ign1 and term 86 of 2nd relay for ign2, term 85 of both relays to ground, term 87 of 1st relay to BLACK/ white in the ignition harness(use 10ga wire), 87 of 2nd relay to blue/black in the ignition harness(use 10ga wire), term 30 on both relays connect each to their own separate 10ga wire and connect to the battery(fuse them at the battery with 20a fuses).

ckeeler thank you for clearing it all up for me :) For the rocker switch.. would i need a DPDT, SPDT or just a Momentary one? And for the relays i will be using these: (Or equivalent). Power Relay, 12v, SPDT, PCB Mount, 10/12A 125VAC, 10A 277VAC, 1/4HP 125VAC Do i need a more powerful relay that what i listed? David
