DATAP R O-45™
Once the spot has been located, drill a .250” (1/4”) diameter hole in the header pipe.
Insert the probe into the hole and snug it to the header using the band clamp.
If room permits, align the transition spring and the lead wire at a 90 degree angle from the exhaust pipe. This will position the sender tip correctly in the exhaust stream.
Tighten the band around the exhaust header pipe.
Route the probe’s cable to the junction box, using tie wraps along the way, but leaving sufficient slack to easily insert the connector into the appropriate junction box jack. Do not harness the cable tightly, being sure to use sweeping bends and loosely guiding the cable to the junction box. This will allow the cable to absorb vibrations along its length.
The cable may be shortened if required. Cut the cable to the desired length (plus some spare) and carefully cut the stainless steel overbraid back approximately 1”. Shrink tubing should be used over the cable where it exits the connector to make for a neater installation. Make certain that the overbraid in no way comes in contact with the wire terminals in the connector. Strip the YELLOW wire back approximately _” and connect to the plus (+) terminal in the connector such as C1. Repeat the process for the RED wire and connect to the negative (-) terminal such as C2. NOTE: Only this wire can be utilized. Substitution of a different wire will affect the operation of the sensor. REMEMBER - The RED wire must be connected to the MINUS (-) terminal and the YELLOW wire must be connected to the POSITIVE (+) terminal.

TESTING: Change the LCD display channel to the appropriate channel, such as “Exhaust 1.” If the engine is off or cold, the readings should be within about 20 degrees Fahrenheit of room temperature. If the engine is warm, appropriate readings should be seen.
