I don't have my info handy but it is all standard Dodge stuff at the ignition switch and the door locks. You will need a 620 and 1.5k ohm resistor to operate the door locks along with a couple of relays. You will need to set the system to double pulse the unlock. This will also turn on the dome light so don't worry about connecting the dome light supervision wire from the system. The tach wire will be found on the PCM at the passenger side firewall right behind the air box. Remove the airbox and you will see 3 connectors...look for a gray/black wire on the left most connector (most toward the driver's side). This is actually the crank position sensor wire, this means that it may and may not work depending on which system you are installing. The wait to start wire will be found either by removing the instrument panel cluster (right connector, ORANGE / black wire) or can be found under the hood on the upper most of 2 wire harnesses between the master cylinder and the engine itself. If you know where the fuel filter is, they are DIRECTLY above it. It will also be a org/blk wire but there are two of them on the connector. It is the org/blk that is NOT on the "edge" of the connector. There is 1 org/blk on the outside row and then there is another org/blk on the next row over. Use the one on the "inside" row. You can use a voltmeter to test this and it is a NEGATIVE signal.
