I just got this HKS Type 0 Turbo timer and I wanted to hook it up on my Powerstroke. These timers are usually on import cars and they do make harnesses but they obviously don't make one for the Powerstroke. I need a little help here. I got the installation instructions but they only tell me which wires are which. Here it is:

Red - [12] Volt Constant (Check)

Green - [12] Volt Ignition (Check)

Blue - [12] Volt Accessory (Check)

Black - Ground (Check)

Gray - Splice into Parking Brake wire (Not Sure)

Brown - Using a splice connector, connect the brown RPM signal wire to the corresponding "I" in the ECU signal diagram (No Idea) Says that the signal must be a [5] Volt Digital signal or a special part is needed if it is a [12] Volt Analog signal.

Mystery Blue - There is an extra blue wire that I've yet to figure out. In the instructions it only talks of one blue wire but there is actually two different ones coming otu of the unit. One has a brown trace and the other does not. I'm probably going to shoot an email to HKS to see what the deal is

I know the Red, Green, Blue, and obviously Black wires from the gauges install but the others I'm not quite sure about. Is there only one wire that I need to tap into for the Parking brake? And what color is it? And the HKS installation instructions say that the Brown wire is optional to hookup. What would hooking up the brown do as opposed to if it were not hooked up? I guess this is what I get when I try to put some rice part in my truck haha.

Any schematics or anything would also be greatly appreciated.

 

Found out what the extra blue wire was for. Turns out that the second blue wire is for some speed sensor that I don't need to hook up. While looking for the installation instructions I also found out that mine is a Type 1 turbo timer rather then the Type 0 one...
