Anybody know if the tachometer in my 1990 corrado is compatible with the W plug routine? Any advice is appreciated.
it wont connect up thats for sure. if you modify it, then you might get it to work.
It won't work but you could source a B3 TD gauge cluster. They pretty much are the same plus you'd get a glow plug light.
I've got a Corrado TD, using a 94 Jetta TD cluster.
There's a plug off of the diesel alternator with a red wire coming out of it. I ran that red wire and spliced it into U1/06 between the fuse box and the cluster.
Thanks a lot, guys. I think I'll try the dakota digital interface, since I'd like to keep the cluster.
