With all the items in hand, let's start putting them together. I'll briefly describe the steps for installation.
Step 1: With a Star screw driver remove the 2 screws holding the OEM IRVM;
Step 2: Remove the Driver's side A-Pillar rubber beading and plastic trim carefully using the panel removing set. Two clips hold the A-Pillar.
Step 3: Fit the Auto-dimming IRVM in place and tighten it - I have used rubber washers to dampen any vibrations. Placed them between the IRVM bracket and screws.;
Step 4: Route the wiring from the IRVM through the headliner then through the drivers side A-Pillar to the fuse box below which is the power source for the IRVM. The fuse box is located above the accelerator pedal at a very inconvenient location (Just above the front right wheel well).
Step 5: In the fuse box, check for the ones that will be functioning ONLY when the ignition is ON as I didn't want the IRVM to draw power from the battery even when the car isn't in use or during day time where the auto-dimming function is of no use. Of the open fuses, found No. 36 to be working only when Ignition is ON.
Step 6: With the Red wire acting as the power source, crimp it directly to the blue connector which is also called as butt connector that will be securely holding the connection after crimping. Insert the heat shrink tube prior to insulation the connections. After taping it, pull the heat shrink tube over the insulation and apply heat using the hair dryer to seal the connection properly.
Step 7: One left is the Black Wire that is to be connected to Ground/Earthing. I chose a metal frame of the unit that holds the hood opener and fuse box frame holder after crimping. Insert the heat shrink tube prior to insulation the connections. After taping it, pull the heat shrink tube over the insulation and apply heat using the hair dryer to seal the connection properly.
Step 8: Add an appropriate fuse in the fuse tap unit to protect the circuit and the car electrical system. I chose to add a 5A fuse at the farther end of the fuse tap.
Voltage: 12V
Power drawn: 2W
Fuse required: 2W/12V = 0.16667A Thought if using a 2.5A but decided to be safe hence stuck to 5A.
Step 9: Refit the driver side A-pillar trim and beading after securing the wiring.
Step 10: Turn ON the ignition and check for the functioning of the IRVM.
