I have seen some pics of the factory/dealer add on tach. Where can you get one that is around the same size/look? I found them on the isspro site but I think I read they are only 2-1/16"? That seems kinda small, I was hoping for something a little bigger. If I can come across a factory one, whats a fair price to pay for it?

Thanks,
Jason

 

factory ones usually go for around 250$ range. theres one on ebay buy it now for 380$. Just wait and one will come up cheaper

 

Ya I saw it, I thought 380 was a little much...

would a 2nd gen tack run off the first gen's crank sensor?

 

I love my factory tach, worth the money IMO.

 

Here's a question for you factory tach equipped owners: How does the factory route the wiring from where its mounted on the dash? Do they run the wiring behind the windshield or A pillar? My plan is to buy the Isspro R5503 Tachometer and mount it in the similair configuration as to the factory one. Any close-up pics would be helpful.

 

i got mine for 20 bucks at the local junkyard mine is mounted on the dash with the wires ran through a hole i drilled in the dash

 

The wires for ther factory tach go right through the dash. There are three wholes: 2 for the bolts to mount and one for the wires to go through. I personally do not have mine mounted there.

 

Here's what I did . . . . https://www.dieseltruckresource.com/...d.php?t=173561

Hope this helps.

 

I have a question now, If you have an Autometer tach for say a car, could you wire it for a diesel? and the wire thats needed for the signal wire hook it to the tach signal wire in the harness and then just wire the rest like you would normally, and then cut the wire in the back to make it read for a 6 cyl.?

 

It would work(mine did) as long as the tach would read the 5v signal.

 

I used Isspro tach, it's on left not a good picture.

 

BC847,

I have read your article many times actually........... I plan to "mirror" what you did, with the exception of using a trans temp gauge instead of a tach. I plan to later buy the Isspro R5503 tach and mount it in the same factory-style configuration (corner of dash top). Does Isspro or any other companys sell a mounting pedistool for the R5503 and similiar models? I definiately like this setup.
