Extending Post O2s for supersprint

Piper1 · 03-29-2021, 11:04 AM

So I'm finally having the time to get to my post O2s to extend them to the supersprint section 1 cat location. Currently pre/post are in the racing dynamic headers. Has anyone done this, know of extension wires for the M54, or just used bosch's universal with extra length wiring?

Trace the wiring back along the firewall and you will find a bundle taped up.

I have successfully unbundled and extended wires to the secondary sensors in section 2. Lots there for section 1(header) sensors also.

Urg my mistake on section numbers blame it on fat fingers. I need to get the posts to the port at the ss cats down the exhaust channel, have catless racing dynamics headers so need to get them to the ss 2 section not 1. Where your cars are in your pic with O2s that's where I need to go.

There should be lots of wire in the bundle. I recall a bit of rerouting to get maximum length to work.
