Where's the ECU / ECM ???
FYI: the ECM in most 06-current chrysler products is the dash cluster assembly. Be very carefull as this systemis now operating on CAN BUS which means in simpler terms that all signals in and out of the module are data; ie 1"s and 0's like your home pc. Throw out your test light and gat a data probe as its not just - and + anymore. Signals are sent as ohm values and improper probing can result in catastophic results. We can all thank MB for the R & D on this system. Be very carefull, the ECM worth a few thousand $$$$

You are wanting to install your Jet chip under the hood on the drivers side towards the front. You will see the computer module with 3 wire bundles (4 if an automatic) coming out the back (towards the rear) I beleive it is the terminal with white paint on it that you want to take off and install your chip in the the ECU and then the wire bundle in the back of your chip. I can't remember the exact plug for sure, just follow your instructions.
