Disconnect old oxygen sensor connector from vehicle harness using extra care not to damage connector, as it must be reused.
Remove old sensor from vehicle using an O2 sensor socket or 22mm wrench. Place the old and new oxygen sensors side by side on a flat surface, preparing to make an accurate cut of the lead wires. Cut the lead wire(s) of the old sensor to a length that when the plug end is spliced to the new universal sensor, the overall length will be the same or slightly longer than the old sensor.
Important!! Before making the cut, add 2” to 3” of additional length to the plug end to allow for the extra wire needed when makingthe staggered splice. See following diagram.
Stagger-cut wire lead(s) stripping off approx. 1/ 4” of insulation from the end of each wire.
>>> For steps #4 and #5 please refer to the attached wire placement & colour coding diagrams in the Installation Instructions (pages 4-12) to determine proper wire matching of universal sensor lead(s) to connector lead(s)
for each specific application (heater wires are not polarity dependant).
WARNING: DO NOT CONNECT TO YOUR SENSOR IF YOU CANNOT MATCH WIRE COLORS.

A) On universal sensors where heat-shrink tube(s) are already installed: insert just striped portion of wire(s) into crimp terminals of new sensor and crimp terminals
B) On universal sensors where heat-shrink tube(s) are not installed: insert just striped portion of wire(s) into crimp type "butt" connectors (approx. 1/4”) and crimp.
After all connections have been made, slip the heat shrink tube over the crimped connections and heat the tube with an appropriate heat source until the connection is completely sealed, taking care not to over-heat or burn tubing (see fig. 3, pg 3).
Remove protector cap just prior to installation
A) Flanged applications-(where flange is notalready installed on sensor) Install flange to exhaust manifold first, then mount sensor in flange (a copper gasket is bonded to the flange & no additional gasket is required)
B) Flanged applications- (where flange is already installed on sensor) it is important to use the supplied gasket before installing sensor)
If not already coated, apply (enclosed) anti-seize to oxygen sensor threads
Install sensor body ensuring lead wire is not twisted or bent
Install all sensors with new gasket supplied & torque to proper specs as below:
-- M18 sensors - install finger tight then 1/2 -3/4 turn with wrench / O2 sensor socket 35-45nm
-- M12 sensors - install finger tight then 3/4 - 1 turn with wrench / O2 sensor socket 18-23nm
Connect and route lead wire as originally installed.
Warning: Anti-seize compound may cause irritation to the skin or eyes. In case of contact, wash affected area with soap and water. In case of eye contact, flush with water for 15 minutes. If irritation persists, consult a physician. If swallowed, do not induce vomiting.
