Adding Extra Length To Some Wiring - Advice Needed?

Hi all,

I've been fitting a new exhaiust to my 2012 Thruxton and have run into a few problems. Although I've had it all up and running and it sounds and looks great, i'm really not happy with how close to the exhaust pipes the O2 sensor wires are.

I didn't think I would have to add to the length of the wiring so that I could route them safely away from the exhaust pipes, the instructions/video tutorial led me to believe I could just re-route them and it'd be fine. But it's not so I've decided to snip the wires, add in some length and then crimp and heat shrink them. Then I'll have enough extra length in the wires to route them safely and it'd be a better job overall.

I'm simply incrreasing the length of the wire not powering anything extra here but before I plough ahead would this wiring I have be suitable? I'd rather not fit it all only for it to fail on me and I have to do it all again ...



Thanks for the help,
Sean.

 

Thanks youngy but I'm at the point of no return now as the 02 sensor wire had already been snipped. Just wasnted to check suitability of this wiring in case there was something else I should have used? This particular modification has been done by others to lengthen the wiring, it's also included as part of the instructions from TEK where the exhaust was purchased.

 

Thanks stripple, yes I’ve made the cut up by the plug end rather than down by the sensor that’s in the exhaust.

I was going to get the cables set up inside tonight and then do the rest out on the bike tomorrow but just wanted to check the cable I’m using to extend will be suitable.

 

Oh no not something else

 

Yeah permanent crimps, butt connector then wrapped. Planned to add about 15” with the wiring, do you think that’s too much?

 

In all honesty at this stage I don’t know. Its taken me a year to get ready for buying the exhaust and when I did finally buy one I didn’t get the one I’d spent a year waiting to get! So who knows what’s down the line.

This exhaust has been a right nightmare though. The video tutorial the guy gets in on his bike in 3 mins! Took me over 3 hours just to get the old ones off!

 

Maybe I’ll lose a few inches. I was probably overdoing it. I think in Delboys YouTube video he adds about a foot when doing the same thing to his scrambler.

 

I would’ve normally soldered but advice from others who have done this say that permanent crimps are better in this case as the wires run near very hot parts, so don’t want to risk the solder melting.

 

I’ve only fired this one up the once and even with the baffle in it sounded tons better than the stock exhaust. If it still works after I’ve mucked with the wiring I’ll try and get a video ... never sounds great through a recording but might give you some idea.

 

You could well be right, the sensor wire does have something around it in places. I’m just going off Delboys YouTube video for this mod so following his process
