Install Essentials 454T Alternator RPM Detector

great price, fast delivery and works like a charm, as a installer at best buy I cant even get this product through work and if I could not as cheap as I got it here.

This thing was never did work correctly. Took it off. Found a tach signal another way after trying to use this failure of a product. Waste of money.

Installed 6 plus mo. Ago had to select a pickup wire @ three different times to finally get unit to crank diesel to start in cold weather does what it is suppose to

It worked ok when it worked; but then it broke. Twice. That is, I've gone through two of these, and won't be trying a third.Aka, perhaps I didn't install it properly, or perhaps it's just too cheap, or perhaps I just happen to get the wrong two items that were not made to spec.The buyer I bought from was really good on returns. So I returned the first item no problem. I haven't bothered with the 2nd.You can try it - it might work better for you, and if it does, it's worth the, what, $40? But I'll eventually be upgrading to something a little higher end, and hopefully of better quality.
