Hi, Im new to the site, and am driving a 1993 400e. Im trying to hook an aftermarket tach up, and am trying to locate the distributor coils to do so. Also, if you have any other help you could give me as to what 12v source to use and where to go to the firewall, it would be much appreciated. Thanks!

Ive got pics of the engine if you need them to help point them out.

And here is what i have done to my car
Custom Y-Pipe
R-1 Racing Muffler
Custom Intake
Removed foglights and headlight washers for airflow
