How to Fit a Cavalier / Calibra Fuel Computer Switch

(applies to Cavalier and Calibra, Carlton and Senator may be similar)


1.  Remove trim under handbrake lever.  Use flat bladed screwdriver to lever trim panel away from surround at points arrowed…
Step 1


2.  Remove the centre console surrounding the handbrake lever.  Two screws (RED arrows!) hold the front end…
Step 2


3.  Two screws (more RED arrows) hold the back down.  Once undone you need to unclip the handbrake gaiter, I did this by gently pressing inwards with a wide flat bladed screwdriver.  There are several clips to undo and it’s fiddly. Don’t be tempted to force them, otherwise they’ll easily break L Lift off the whole handbrake surround panel, not strictly necessary but you will struggle to cut the coin holder out without doing so.  Cut the coin holder very slowly.  You need to keep a flange for the switch to sit against.  The ends of the hole should be filed to match the clips at each end of the switch.   Once the hole is cut, fit the switch with the raised button at the rear and begin re-fitting the centre trim panel.  Leave all of the screws out for now, as you need to plug the switch in BEFORE it goes down fully.
Step 3


4.  The wiring connector shell is visible. The wires going forwards are part of the loom, those going backwards (hidden in the pic) are for the window switches and FC control switch.  A metal locking bar holds the connectors together. It won’t lift up fully until the centre handbrake surround has been lifted and the white spacer (bottom) has been removed.  Lift the metal bar up, from the front edge and over the top of the connector block. The connectors part automatically.
Step 4


5.  Three connections are shown here. The two to the left hand side at the front are for the electric windows. Cars with front electric windows will only have one connector here.  The white connector to the right (BLUE arrow) is the loom connection for the fuel computer switch.  Once the connectors have been parted, the connector shell is accessible. Push the FC switch connector into the empty location to the right of the window connectors. The plastic connector housing is keyed to stop it being fitted into the wrong slot, or the wrong way round. I don’t think you can get this bit wrong.  Once the FC connector is installed, plug the light grey/cream plastic holder back into the loom connector and close the metal locking bar.  Refit the spacer and then the centre trim panel. Only when the centre trim panel is screwed down from the rear two and front screw, refit the handbrake lever gaiter. Then refit the screw that holds its front edge down and replace the dished trim.  As a very rich author suggests, ‘re-fitting is the reverse of removal’
