Monster Tachs make baby Jesus cry... Don't... Do... It...


In all seriousness though, I don't have the answer to your question. So, I guess this is a bump for ya.

 

Tap into your gauge cluster's tach signal wire and set your tach to 4-cylinders.

I'm hoping you don't do it, even though I told you how.

 

Nothin wrong with a monster tach, I'm running one & love it. WAY better than that POS stocker thats never right. I used to just have a Harlan shift light in the pillar but wanted a accurate tach & a nice monster tach solves both.

I just tapped into the tach signal output wire from my PCM for my install. Works flawlessly. But like stated above, set it to 4 cylinder mode otherwise it'll read exactly half the correct RPM..

 

Monster tach is ugly as hell IMO. But, your RPM wire off the PCM should be pin #10. I am going by memory though.

good luck with your install.

 

ya red connector pin 10 white wire.set up as 4cly 2 pules.

 

That is understandable, I'm still not a fan of it though. I did get an idea for my 1989 Silverado though while riding in a car with a monster tach. I'm thinking about getting a single gauge pod/pillar and I'm gonna put a nice little 2 1/16" tach in it.
