Shut off switch

Good morning.

You can install it but it could play games with your anti theft or security where the key will forget the password and will require relearning the password. That process can be pricey as dealers and locksmiths are among the ones who can do it.

Why are you doing this operation? Have you tried finding the issue?

I cannot say I would do that. It is not good for the PCM. Plus, if you use it, it will constantly be clearing your codes out, and your car will never pass an emissions inspection. Just my $.02.

Well if an electrical short is your problem, there is a test that anyone can do to find it. All you need is a multi-meter ($15.00 to $20.00 or so at AutoZone). Disconnect one of the battery cables from the battery. Take your multi-meter, turn it on, and set to twenty volts DC. Take one lead and connect it to the newly disconnected battery cable, and connect the other lead to the battery post. You may have to MacGyver it to keep the leads connected (maybe use tape or something). You should see some sort of reading. Now start unplugging fuses, one at a time, until you see a significant drop in the meters reading. You have now identified the circuit. If the car has any aftermarket electronics (like a radio, for example), then start with checking that.

This is the multimeter that I have: http://www.sears.com/craftsman-multimeter-digital-with-8-functions-and-20/p-03482141000P?plpSellerId=Sears&prdNo=1&blockNo=1&blockType=G1

Let us know which fuse it was and I will personally look up what is on that circuit.

Sorry Roy, did not mean to jump in on you.

No problem, good information.

Nice work team.

Okay. Another way of checking this is to remove the negative cable again and put the volt meter in line. Set it on amp scale and see how many amp is being drained. The figure you are looking for is 50-75 milli amps. If you have more, then remove the fuses one by one until the draw goes down to the spec.
