A. Double check that the battery cable is disconnected

from the vehicle.

B. Remove the passenger side front kickpanel from

the interior of the vehicle. Remove the sound

deadening material (if any) that is covering

the ECM. Remove the plastic ECM hold-down

bracket.

C. Using a 10mm socket or wrench, remove the

harness and plug from the ECM (as you loosen

the bolt, the connector will slowly release).

Remove the ECM from the vehicle.

D. Gently remove the plastic service port cover on the

opposite end from the main harness connection.

The main circuit board with a double sided

electrical edge connector will now be exposed

(see Fig. 12-a).

E. Using alcohol and a cotton swab, carefully clean

the grease off of both sides of the main circuit

board service contacts.

F. Using a sharp knife, small at screwdriver or

scraper, gently scrape the remaining thin layer

of silicone off of the contacts. This can easily

be done by removing the corner screws on the

ECM and opening the cover to better expose

the connector to be cleaned. DO NOT remove

or damage the electrical contacts. If the silver

contacts start to give off ne metal shavings, you

are done. STOP. It is extremely important that

all of the silicone be removed from the contacts.

If the surface is not completely clean, the

vehicle may not start or run properly. If the ECM

cover was removed, reinstall it at this time.

G. With the ECM service port contacts now clean,

you are ready to install the ECM module. Align

the module with the ECM (see Figs. 12-b,

12-c). Slide the module onto the ECM by applying

gentle pressure evenly. Apply the supplied section

of adhesive tape to the top of the ECM and module

to resist movement from vibration.

H. Reinstall the ECM into the vehicle. In some cases,

the extra height of the ECM module will not allow

the use of the factory ECM bracket. Reconnect

the factory harness and reinstall the factory kick

panel.

NOTE: Improper contact cleaning is the largest rea-

son ECM modules fail or work improperly.

NOTE: When the ECM is sent, the following step will be

performed by Vortech to ensure proper cleaning

and module installation. (Step 12 is for reference

only.)
