[quote]You can find an ignition wire and illumination wire behind the radio...the yellow wire (next to the ornage wire) is the ignition and the brown (same section as the yellow) is the illumination. Or you can tap any pink wire in the ignition harness for the ignition and the brown wire behind the headlight switch for the illumination.
Do a search for the tach wire...its either pin #35 or Pin #10 at the PCM. I believe its 35 for the 98s and 10 for 99 and up.

What year is your car? It is pin 35 for the 98s and pin 10 for the 99s and up. <img src="gr_stretch.gif" border="0"> You also need to clip the orange and brown wire loops behind the tach to put it in four cylinder mode. Check the instructions to make sure I've got the right colors. <img src="gr_images/icons/wink.gif" border="0">
Good luck,
Justin

Re: Monster Tach install Marty,
On your 2000 you are looking for a white wire in the number 10pin location on the PCM. This will be the one that is towards the front of the car of the 2 PCM boxes. Don't forget also that the tach uses a 4cyl. pickup! Good luck, it's fun turning on the shift light....
