I decided to go through all of my connections before I touched the car, so I put all of my stuff in an excel sheet.

I used the Hitman Install page as a base and adjusted for the new platinum series. All of the wiring came labeled from haltech so it was pretty easy to figure everything out, a couple of questions were answered by Chris Ludwig and this is what I have come up with. I also tried to make notes where relevant and reference a thread in case there are additional questions.

Good thing to print out and have with you during install.

This is all based on my install, which is an n/a, so it doesn't cover everything.

 

Looks good. Should be stickied.

 

Just a note on this. PWM 1 should always be reserved to drive a tach. It is the only output that can run the positive voltage pull up that a tach needs. Unless you are out of outputs and need to use it for something else I'd recommend just not using it if you're driving your tach with a coil output or something similar. This way, in the future if you need to drive a tach with the ECU, PWM will be available and it will be easier to wire it.
