I have been using one for a while now . Works perfect . There is a couple threads on the install as well from a while back. Do a search and you should be able to find them . If I remember correctly you have to put a up resister on the tack wire to get it to power the tack . The pcm does not have enough power to drive the tack on it own . You will find this info in the the past threads as well . Ls1nova is correct . You will have to change the tach signal as well in the pcm .

Heres a picture of mine .
