A1 to a4 manifold swap. O2 problem

[ingold]

Purchased full exhaust off of a a4 to put on my cb. My problem is that the o2 is in the downpipe now and is also a male end plug. My harness is for an a1 which is female and also not long enough. Do I need to create some kind of plug and play extension with jy plugs? Or is there a more simple solution? The a1 manifold is 4-1 and the a4 is 4-2-1.

You can release some wire from inside the loom so that it will stretch but you'll need the connector end if you intend on using an A4 harness.

Do as Jarrett said and unravel the stock wiring to reach, then get a new o2 sensor designed for an A1. It'll screw right in where the A4 sensor is.

thanks for the quick replies.
