fitting diesel rev counter

[lloydy]

Hi, i have managed to get hold of a diesel rev counter to fit in place of my clock in the dash pod.
Sooo, from what i understand the dash end of it is a straight swap with no wiring alterations needed. The engine end, will i find the wire for the tacho in the loom somewhere? And then just extend it to the W terminal on alternator?
If the wire is in the loom, where will i find it? If it isn't what have people done to solve this.
Year of van is 1990, if that makes a difference and is a syncro
thanks, Lloyd

Pretty sure the wire for the W terminal was either hanging round near the blue or already connected. Red and white wire from memory.

Cheers, i'll have a look

i got a blue wire and a red/black wire already attached to the alternator with a little plug (AAZ alternator) So looks like i should just be able to swap clock for tacho and not have to do anything else

Looks like I need the rev counter dash pod, can't see it working otherwise

dash pcb is different

wires are all in place as the oil buzzer uses rpm signal

you need ideally a complete dash pod.

clock pod has a adjuster hole for the clock hands .

you can live with this , but you will need a tacho pcb , and a diesel one.

or some dodgy wiring is needed!

Thanks for that. Question then, i have a diesel rev counter on it's own and obviously have my diesel dash pod with speedo/clock. If i got myself a petrol rev counter dash pod and put my speedo and spare rev counter would it work? or are the pcb's petrol/diesel specific?
thanks, lloyd

pcb's are specific to fuel, no glow plug led or connections on a petrol

Thanks for that
