diesel tachometer

Not sure where to post this question, so hopefully this forum will do.
I was curious about up-grading my current dash layout, to include a tach. Currently there's a large fuel gauge to the right of the speedo. And in the LHS pods, there's an M/T spot lower left. I've seen the layouts with the large tach next to the speedo, and the small fuel gauge in the lower LHS. My question is the wiring. Is there connectors incorporated in the harness to do this, or does it have to be fabbed? I've gone back a few pages here, and can't find any info on this. I'm sure it's probably been brought up in the past. Thanx.

Never seen a factory tach in the older 6.2 trucks....lots of gassers had them but I have never seen a diesel.

I have a Tiny-tach in my van that works good and is VERY simple to hook up. DOES not look factory at all but functions very good.

I have an ISSPro in my blazer that was small enough to mount in the open gauge hole to the left of steering column. I looks nice and functions like a regular gauge.

Hope this helps...
Good luck

thanx Dog. Wonder if there's a way to get the factory tach to work on a diesel? I've heard they work off the alternator some how. Have to look into it.

Not sure about a factory tach, but Autometer offers these: https://www.youtube.com/watch?v=HhLPAPZxNsM

I also know that there is quite a bit of information out there for converting a gas VW tach to work on a diesel VW engine, such as this: http://www.4crawler.com/Diesel/Cheap...er/index.shtml

You could probably do the same for a gas tach of similar vintage for your C30, but I have no idea how hard it would be to figure out.

Interesting design how the sensor works on the Autometer tach. I'm thinkin there's a better way of attachment than a large worm clamp. I'll have to read up on the VW info. I'ld sure like to make the factory tach work. I have my shop manual, with the electrical schematics, and none of it mentions a tach.
I'm sure there must've been an option on one of the years with the 6.2.

Never seen a 6.2 with a factory Tach
