Where do I find the Tach Input on the car? Do I have to have the Aux input and output connected to something (not planning on using the input but the output I want to use to control a fan)?



Thanks

There is a Yellow/Blue wire I believe in the stock harness that you will disconnect from the old clip/connector and it will go in the bottom left slot of the trailing coils.



I know that makes no sense....but, on the trailing coils harness, you are running the Grey/Black and the Grey/Red wire to the Pink and White wires coming from the coilpacks. Those two are the top two wires in the 4 pin connector....now on the bottom row, below the pink and white wires are two more wires....one is Yellow and one is Grey....you want to connect the old yellow/blue wire in the orignal harness to the yellow wire on the coilpacks harness. Then your tach will work.



Hope that helps.
