B18c O2 sensor plug on wiring harness came out! Help!

When I took off my down pipe I accidentally spaced and the wires came out the connector, the four wires are purple, yellow, gray and a thicker tanish wire... Lost

Can you post pics? What year is the chassis? What harness are you using?

91 civic hatch b18c swap. Not so sure about the harness, probably stock.

Go to the junkyard and chop off another oxygen sensor pig tail. Using red 3m heatshrink butt connectors, splice it onto your wires. Using a lighter, heat up the ends to secure the connectors. And you're done.

The wire colors you posted are not stock color wires. Can you post pics of the harness? The 91 civic used a 1 wire O2 sensor. So one added in the 4 wire O2 sensor wiring.
