it is a (-) output from the alarm. Did u test for that? If still no signal from the DL wires, I would think you need a new brain.

Good chance of a bad brain if there is no - output.

You need a transponder bypass for that vehicle. the 555F is normally the best bet. Put your key in the ignition and see if the car will remote start via the remote.

since you cant find the tach wire see if the alarm has a current sensing option to replace the tach. if not then you need to find the tach. using a meter set it to AC and it should increase with the engine RPM while probing tach wire.

If you can't locate a tach wire your alarm should be able to learn a fuel injector control wire. My wife's lexus I found the Tach wire under the dash. It was an orange 22awg wire. If that fails then the next best thing is to garb a fuel injector wire. If you pull apart the electrical connector to an injector you should see 3 wires. 1 will be +12 volsts, 1 will be groud, and 1 will be the contorl wire. Thats the wire you want. ------------- Jeff

What you have to do is use a multimeter to double check the information you are looking at. Info from two or more sources will not be the same. ------------- itmdtr
