Smashed the O2 connector

[Srphatness]

So I had to drop my transmission to change the slave cylinder.
When I put the transmission back up to the motor I pinched the connector that goes to the O2 sensor on the passenger side, and completely destroyed it. In need of a working truck I went to o'rielys to see what they had for a four pin connector. . . .

All they had was a trailer light connector. I said F it

So I just snipped off the wire just before the connector and crimped the trailer connector in it's place.

My check engine light comes on now. O2 sensor (who'da guessed)

there was one crimp I was not to sure of, so I'm going to redo it.

The check engine light does not come on immediately. it takes a while, usually at idle.
So, I'm thinking that a crappy (hurried) connection is changing the resistance of the wire, which changes the return signal current, which is what I am assuming these O2 sensors run on.

So the question is:
Do you think that the fact that I have an extra foot of 14ga wire on the original 10-12ga would add enough resistance?

Can I not just crimp a connector, or do I have to buy a stock connector and run the wire all the way back to the computer?

Hoping I can just crimp for obvious reasons. Never worked with O2 sensors before so I dunno ??????

The O2 sensor uses a volt range of 0-1V. Unless you're 100% sure of your connections, I would check them again. Also...any corrosion that happens in the connector or in your joints will affect the signal. This is one spot where you will want to solder and heat-shink those connections. I would stay away from trailer connectors.
