Well hopefully you haven't damaged anything, I'm sure you'll sort it todsy
Sorted. I had used the wrong pin as I suspected. Put the incorrect pin back into its slot and used pin 6 instead like I should have originally. Stupid move on my part not to triple check.
Everything is now working as before thankfully and I got the sensors coded with on-screen guide!
Thanks to ALL in this thread!
Not everyone can do the perfect job, plus if your relying on someone else your just hoping there able to make a good attempt, the solder joint whist not being the best in the world will do as long as it's insulated well.
You've got to remember not everyone is a retrofitter and has fantastic diy skills, so it might have to do for now.
Like I said, I'm not too pleased with the soldering job, but it will do for now as the system is working well.
He puts some insulating tape around each open circuit - he seemed happy enough.
I'm just stoked to have OPS working :)
