So let me say first off, it is fricken COLD. I have a small project going on inside with the engine wiring harness. I decided to try and add a "W" terminal hookup for a tach. I started with taking the back cover off.
Then I picked a terminal that looked to have the most room for clearance etc.
I drilled two access holes. One for a screwdriver, and one for the wire.
Made a new wire. Double heat sink cover.
This is what it looks like all back together. I am going to use the original alternator wires, which I cut out of the dodge, and run them to the battery, ground and voltage regulator.
Has anyone used this method for the tach signal? I have only read about it and have not tried it. Any and all feedback is greatly appreciated.
