Phoenix Module Installation Instructions
Before proceeding any further,
Open the hood and locate the computer (PCM) harness connector. It is located behind the air filter box on the driver's side firewall, next to the "doghouse" cover. The connector is rectangle shaped, approx. 1" x 6" with a 10mm bolt in the center. Using a 10mm socket, remove the connector from the PCM. The bolt is attached to the connector and DOES NOT come out. You may have to remove the air filter box for access to the PCM and connector.
There is a large black grommet holding the PCM in place. There are two 10 mm nuts, one on each end of the grommet, holding it in place. Remove these nuts and then remove the grommet.
Remove the PCM from the vehicle taking care to not the orientation of the PCM. The PCM can fit back into the vehicle upside-down and will not allow the harness to be properly reconnected. Remove and save the black plastic cap from the rear of the PCM.
Most PCMs will have a coating of clear silicone covering the connector. This coating MUST be throughly removed in order for the module to make proper contact with the PCM circuit board.
It is recommended that you open the PCM case by removing the 6 case bolts with a 7/32" socket. This allows complete access to BOTH sides of the connector to ensure that it is clean. The PCM circuit board is sealed and is quite robust. However, to avoid damage from static discharge, it is recommended that you avoid contact with any of the internal components wherever possible. Use the provided Scotch-BriteŽ pad to clear away the silicone. Acetone (nail polish remover) helps to clean the connector.

(Note: DO NOT USE CARB CLEANER, LACQUER THINNER, OR ANY OTHER AGGRESSIVE SOLVENT TO CLEAN THE PCM CONNECTOR!! It will damagethe fiberglass resin on the circuit board and permanent damage to the PCM can result!!)

BOTH sides of the connector must be cleaned thoroughly, but avoid being too aggressive. If you are cleaning the connector and begin to see copper, you are cleaning too far. This may result in a poorly fitting or loose module.

Once completed, reassemble the PCM case BEFORE installing the module onto the connector. This ensures that you do not accidentally install the module upside down.

Note: Failure to properly clean the connector may cause the vehicle not to start and/or may damage either the module or the PCM. Any module that has failed due to improper installation WILL NOT be covered under warranty.

Note: 98% of all tech calls involving a No-Start condition can usually be traced back to poorly cleaned contacts. Please take your time and clean the PCM connector thoroughly as it will save you unwanted headaches down the road.
Fasten the module to the PCM using fiberglass duct or packaging tape. Reinsert the PCM in the vehicle, being careful not to crimp or cut the switch wires between the body and the PCM. Install the complete assembly back through the firewall in the reverse of the removal. Make sure that the label on the PCM connector is facing the direction noted during removal. Reinstall the sealing grommet. Reconnect the PCM harness connector. Reinstall the air filter assembly if it was removed.
Turn on the ignition key and check for proper operation of the "Wait to Start" or "Glow Plug" light. If no light appears, TURN OFF the ignition key, remove the module and re-clean the edge connector. Once the light operation is verified, start the vehicle and verify that it appears to be operating correctly.

NOTE:The "Check Engine" light may blink very quickly, appearing as little more than a slight flicker. This is an acceptable indication of normal function.
If equipped, mount the rotary switch in a convenient location, taking care to ensure that the lock tab for the switch is inserted in the hole that corresponds to the number of positions programmed on the module.
Now make sure your teeth are brushed. Once you start driving, you'll be smiling like crazy!
