Wiring Help required

[Tonks4x4]

Ok I need some pointers if anyone can help me. Specifically Paul if your around....

I need to wire up the rev counter on a UR Green style digi dash any pointers on how it's done. I know the signal used to come from the sender on the flywheel and I know there is an ecu for some of the dash functions....I don't seem to be able to find the correct drawing for it as all the drawings I have are in German for the index.

I know the feed from the 3B loom is from black connecter position 7 Green/Blue

I know that all the analog style dashes are fed with Ro/Sw/Ge.

Cheers for any assistance.

I'm not up on the UR digidash unfort - what year does that hail from and I can seek out the schematics - or you can from 'kerbside motors'

I dunno if the digidash takes rpm signal straight from the flywheel sender - I feel thats unlikely as even the earliest UR would have had some sort of ECU for electronic ignition - all be that fairly crude compared to Motronic.

THIS kerbside motors - Phil Payne's mighty site for the wedged wonders

A quick look says Green digidash is for a MAC01 ECU on the WR engines... Kerbside must have the answer - those schematics are in Englisch

Brian,
PM quattrodan he's done this on his 3b ur conversion.
Cheers,

just find the lilac (purple) wire under the ur fusebox area and splise the s2 rpm signal into it.

Sorted thanks

Another quick question how does the S6 get a boost signal to the OBC display????

Can this be used to feed the UR dash from a 3B ecu?

iirc people have in the past had a wr ecu powering up just for this signal but I could be wrong.
