Default DIY Fuel Pressure Sensor Logging Cobb Access Port

I was installing an adjustable fuel pressure regulator and really had no need for the complete fuel pressure sensor kit from Cobb so I did a bit of searching around and came up with the 'how to' and parts list to DIY it. Saved a bit of money and didn't end up with parts I had no use for.

This is for the access port and Cobb Custom Feature. Instructions for activating can be found in Cobb's fuel pressure sender install sheet towards the end.

You'll need Auto Meter parts -
#2246 (sender)
#5227 (harness)
And a TGV connector for clean install-found here

Cut the red/black wires off the Auto Meter wiring harness. Use the following hookup to the TGV as pictured below-
Black - ground
Violet - 5v Signal
Grey 5v Reference

Proceed with activating the CCF in your ATR software. I had to slow the sample rate to 120, and set smoothing to 0.2500 so I could set a good solid base pressure.

Here is the TGV plug for reference.
