3 Map Sensor Install problem
Hey fellas, long time browser on these forums. I've had my HHR SS for 17 months now and decided to install a zzp high flow cat downpipe, 3 map sensors, and the trifecta tune all at the same time. Yeah, I ran into a problem. When installed the 3 map sensors with the plug n play set up the top sensor didn't need the plug n play cable? I ask this as a question because I got this HHR used and that maybe the previous owner had GMS stage 1 installed at one time. I say this because in the picture I've included has taped up wires that could have been spliced
Now because of this I'm on safe mode running only 5lbs of boost. Help or suggestions would be greatly appreciated.

Here are the install instructions, you can double check the wiring, maybe a wire is crossed somewhere.

Thanks for the replies!
I'll check the diagram and see if the wires have been spliced. If not and the plug in play connectors in the picture can not be connected then it looks like I'm gonna have to splice the plug in play into where the old connecter is right now.

While your checking the wires. If they used but splices. Get rid of them and solder and shrink wrap the connections. In my hhr they used them. My car kept going into limp mode. Giving me maf error codes. And other random codes. I soldered the connections and the problem went away.

Problem Fixed
So the previous owner did pigtail the stock wiring because they did have a stage 1 in this SS. After I got my plug n play wiring soldered on both sensors(yes I forgot about the lower MAP sensor the first time and had to go back) my SS is running beautifully. Definitely can feel the difference in brute power with a Trifecta tune.
