Speedo Pulse Wire? Which Wire?

[Mark Elvin]

Fitting my Waeco cruise control & I do not have a speed conversion chip fitted. I'm trying to identify the pulse wire for the speedo, I'd rather get the right one first time than have several attempts. Does anybody know which wire in which plug on the back of the instrument panel is the speedo pulse please?

Thanks in advance

Its the Blue/White and White/Yellow on the 1C and 1A pins;

From memory its blue/white, and the one obviously behind the speedo - there is another one the same colour behind the binnacle.

Hope that helps.

SP+ on the instrument panel PCB should also work. That should be where the blue wire goes in this picture where a chip has been fitted:

Sorted it.

It's the Blue & White that feeds into SP+ on the back of the speedo.

Cruise works at treat.

Nice one.

for future readers, this is the blue/white wire in the wider connector that plugs into the central socket on the PCB. (I also had a blue//white wire on the left hand connector)

I picked up using a ring terminal under the SP+ screw, saved chopping into the loom.
