Hi, i just got a 1993 D-350 with the 5 speed tranny and i was wondering where i can get a cheap tach that will hook up to it. I have heard it has a plug in the wiring harness for a factory tach? I dont need anything fancy just something that works.

 

Some guys have had good luck with cheap gasser tachs set on 4 cylinder - others have not. Isspro makes a plug-in tach that will work.

 

do you happen to know the model name of that Isspro tach?

 

Any of Isspro's electronic tachs will work, but #R8503 is the best match (4k RPM). You need the harness (R8912-92) and the tach

 

just so you know, easily over $100.00
