Cortina + Brantz rally trip problem + Pics

Hi ya folks

I think there are a few folks out there in RR land who do a bit of rallying so heres the story:-

I bought one of these: -



to connect one of these:-



into this:-



So I follow the instructions - check the sensor works before fitting it (it does).

Cut a 15mm section of speedo cable sheathing out and feed the cable through the centre of the sensor - connect it all up. And we have no signal to the trip to count the miles, and the speedo doesn't work either.

Any thoughts? Or any firms/experts in the Surrey/Hampshire area who might be able to sort it?

Thanks folks!
