Use a lubricant on the two purple wires provided with the wire harness (7). Starting from the passenger
lower compartment feed each wire thru the grommet up to the engine compartment. Make sure to feed one
wire at a time, and pull wires careful to prevent grommet from coming out.

Now using an 1/8” drill bit, drill a hole in the specied area shown
below. Make hole bigger by using a 9/32” drill bit.

Now, feed the tube (25) thru the lower/center of the
dash.
Pull down carpet on dash lower/center on
the driver side and pull the tube through from
passenger side. Note: When feeding tube
thru, make sure to position it under exist-
ing wire harness (see picture) to keep the
wires away from the silver AC/Heater tubing
as that part may get hot and cause damage
to wires. Once the tube is fed thru, feed both
purple wires thru the tubing tool.The tube can
now be pulled off.
Feed wires thru the under dash cover as shown to keep wires tucked up out of the way. Connect the OBD II
plug to the trigger wires with Posi Lock Connector (14). Connect the matching wire color/stripe.
