Disconnect the Negative cable first and then Positive Battery Cable. 2. Remove the Ashtray from underneath the dashboard. Slide the ashtray out of the holder in order to remove all the screws. 3. Leave all the wires going to the ashtray connected if possible, or disconnect and reconnect after the installation.
- Page 7 mount the unit to the bottom of the dashboard. BE SURE TO SECURE EVERY HOLE WITH A SCREW. 3. The original wires on the ashtray will hookup, as they were before you added the a/c. (if the ashtray is present in the Jeep) The lighter may have to go on the other side of the unit (passenger side).

Page 10: Installing The Condenser
Step Four Installing the condenser 1. There is not a direct fit in condenser for a CJ. We use the largest universal condenser in this vehicle. The condenser brackets can be bent by hand or in a vice. 2. Drain the radiator into a clean drain pan. 3. - Page 11 13. We recommend attaching the hoses to the condenser before reinstalling the radiator. 14. Once the hoses are attached reinstall the Radiator, and shroud 15. Fill the Radiator with the antifreeze and water. You may have to run the Jeep in order to fill the radiator to its full capacity.

4. If you have a 304 / 360 engine you will not need any additional pulleys. The original setup used two belts on the compressor. The new compressor does not require that kind of tension. One belt will run the alternator; the other belt will run the compressor. - Page 13 Make sure the hoses do not rub any metal. Securing them with tie straps is recommended.

Page 15: Finishing The Installation
Step Seven Finishing the installation 1. Wiring the system: This system only needs three wires to hook up the system. 2. The first wire is a red wire with an inline fuse. This is an ignition wire. Find a source that gets power with the key on, and splice / plug it into that connection. 3. - Page 16 Supplement Gas Pedal Adjustment * On some Wranglers the gas pedal has a tall piece of metal above the hole that the gas pedal cable goes through. If your Wrangler has this long pedal arm you are going to have to cut it down to clear the blower housing.
