Where is my starter coil?

Where is my starter coil?
I am trying to install an aftermarket tachometer on a 2000 4cyl. ranger. I know I can get power from the stereo but I don't know where the ignition coil is and which wire on it to tap into for the signal cable. My question is where is the ignition coil? What color is the negative coil? pics would be appreciated.

I'm assuming you have a 2.5 L engine since you don't have this information in your signature or Profile. Recommend you update for future reference.
To find the coils, simply follow the spark plug wires back to the coil packs. As to which wire to tap and which coil to tap depends on the aftermarket manufactures instructions. Does your truck currently have a tach in the dash cluster? What does the instructions with the tach you purchased state?

From everything I'm finding, they recommend connecting aftermarket tach input (green wire) to the PCM Tach terminal. It should be Pin #48 (Tan with Yellow stripe wire) at the PCM connector. This wire runs from the PCM to the firewall connector and then behind the dash and would normally be used to run the factory tach if installed (note, this wire should be present regardless).

If you tap one of these grounds for your tach it would not properly register the engine RPM. You would have to use some type of an adapter designed for DIS with coil packs Click link summit racing parts
However, I believe you can tap the PCM Tach output accomplishing the same thing without the need for the adapter saving yourself about $80.00 dollars.
