how to hook up a monster tach

not sure on gm trucks but im sure the hookup is pretty much the same. i had a phantom autometer tach in one of my other cars but black was ground, red was constant power, yellow was acc, and blue with the white stripe was to my rpm out wire from the cluster. i also had to solder blue to the actual board on my cluster. good luck man.

Ive never wired one to somethign EFI. Theres a male spade on distributors for tachometer signal, but were obviously talking about something newer here.

What do the directions say to do? I would imagine theres a wire somewhere to splice into.

Well got the tach hooked up today works great thanks with the help

Well..... what the hell did you hook it up to? :wtf:

i spliced into the factory tach and hooked up my hot wire and ground wire and lights and had to cut it for a 4 cylinder

hmmmm, what gauges are on your A pillar pod

air fuel ratio gauge and water

why is the shift light comin on that low? and just curious to as why you put a monster tach?

I set the shift light that low for the video and i put it in there just because a buddy had one in his and i liked it
