Speedo drive

[mini-valver]

Under the impression h1's have a mechanical speedo drive. I have a set of clocks but they are identical to my ph2 clocks ie, grey 30 pin connector, red 15 pin connector. No speedo input?

do you mean Ph1s matey? They dont have a mech, they have elec, but witha speed sensor in the box, ph2's take the speed from the abs rings, so no sensor in box

That'll be the one! Could do with a wiring diagram for the speedo output then

The speed pulse is pin 13 on the righthand connector as you look at it with the dials fitted, its the red one iirc.

I have a diagram for the back of the clocks, just not sure how the speed sensor on the box is wired. Haven't even looked at one, just trying to get some schematics together so when I have some spare time, I can make a loom.....


Need one for the pin assignments on the indicator/wiper stalks too!

The speedo drive for a non abs model is wired as such:

With the speedo sensor connector:

250
VEHICLE SPEED SENSOR
SSABS

A 0.75 AP29 PROTECTED + AFTER IGNITION ENGINE FUNCTION FUSE
B1 0.75 55S ENGINE SPEED SIGNAL
B2 0.75 M EARTH

Will dig out the stalks later on.
