Hey guys. I was wondering how you hook up a RPM tach? I've hooked many up but only on distributors and coil packs. But, this would not be the case haha.

I want to get one to put on my 1991 non-intercooled D250 5 Speed. Any help would be great! I would think you have to get a sensor for the harmonic balancer to read RPM's. Suggestions on what brand and what all I need would be excellent also. Thanks!

 

I would think auto meter would have the full kit for it

 

isspro has a good kit, and if you had a 92-93 they even have a harness to plug into the factory tach plug

 

So the 92-93 trucks actually have a line you can hook a tach up to? I have an autometer sport comp 6 grand tach I've been waiting to put in

 

Cool thanks guys!

 

Yes its under the dash behind the P-brake assembly, as far as I know you need the isspro harness and tach to use it.
