Will this plug directly into my ECU?
- No. You must use a wideband controller (LC-2) with the sensor. This product is a replacement sensor in case you have damaged yours or want to carry a spare.
How can I check if my LC-2 is set up for this or an LSU4.9?
- The sensor cable for an LSU 4.9 will have a "4.9" cast into it. If you have a LSU 4.9 cable, you will want to use replacement sensor part number 3897.
