Recommended Innovate LC-1 Installation

Installation of the Innovate LC-1 wideband kit is pretty straight forward. The LC-1 Installation manual covers most of the basics for a general install. We do, however, have a few specific suggestions and one grounding correction below.

ECU wires

The following is provided for reference in the sections that follow. You can also get detailed pin out information off our ECU wiring page.

Basic LC-1 wire assignments

LC-1 wire Description Typical install point 1G DSM 2G DSM
Red 12V supply Switched +12V source, fused 102 or 107 12 or 25
Blue Heater Ground Chassis ground lug 101 or 106 13 or 26
White System Ground ECU's sensor ground 24 92
Yellow Analog out 1 Unused N/A N/A
Brown Analog out 2 Selected ECU input 4 (or 15, 16) 76 (or 73, 75, 85)
Black Calibration wire Wired according to LC-1 notes N/A N/A

RED wire - notes

The red wire typically goes to a switched +12v source. The ECU pins listed above are good choices if you're wiring near the ECU. This wire would also typically be fused with at least a 5A fuse.

BLUE wire - notes

A good, solid high-current grounding point here. The ECU pins listed above are good choices or you can try a good, clean chassis ground point too.

WHITE wire - notes

The LC-1 install notes suggest that you tie the BLUE and WHITE wires together. They suggest this to keep things simple across all their different customer installations. In our case, we want the best possible reference point for this wire. And that's the ECU's sensor ground point.

The ECU pins listed above are good choices or you can use any of the sensor ground points under the hood too (MAF connector, TPS connector, MDP connector, etc.). But, really, the best place would be right near the ECU since everything you need is right there anyway.

Do NOT connect the BLUE wire from the LC-1 to the ECU's sensor ground. You will damage the ECU's sensor ground track if you do this. ONLY connect the WHITE wire from the LC-1 to the ECU's sensor ground, NOT the BLUE.
