confused O2 Sensors?

Hi All,

Ok so I've just connected up all the wiring in the Capri.

At least we thought we had.

There is a sensor in each exhaust which I'm assuming are the O2 sensors. Now I would also assume that both of these need to be connected.

For the life of me I can only find a connection in the loom for one.

Is there something missing?

The loom is supposed to have been complete from a NF Fairlane. This is the way it was described to me when purchased.

TIA
Ross

Yes the harness you have is incomplete. They went to two halves from ED so yours is likely the same. So, the pricks(sorry but this happens on practically every conversion Ive done) probably only supplied half of it.

You can run without HEGO's but of course it'll never go into closed loop which will result in a slightly worse fuel consumption figure. No big deal really.

Pete.
