Stillen Grounding Kit DIY

djburke87

Hey electronics guys/gals! I want to do a grounding kit on my 7AT Z without paying that stupid Stillen price. I have wires and connectors sitting around anyway, so I figured it would be a practically free project, and if it doesn't add that 50HP, I won't waste my money.

So, does anyone know where the connections point are for the kit? If you have a picture of it, that would be awesome.

A little more indepth:
Wire 1: negative battery to passenger side firewall.
Wire 2: passenger side firewall to passenger side throttle body.
Wire 3: passenger side throttle body to front of engine passenger side.
Wire 4: passenger side engine to driver's side firewall.
Wire 5: driver's side engine to driver's side throttle body.
Wire 6: driver's side throttle body to driver's side firewall

Note to all:
With a "grounding kit" installed with these connections, you have bypassed the battery current sensor, which is used to determine the battery charge rate, based on how much the battery has been discharged. Not good!

Also, for those who have not disassembled the throttle body, grounding the outside metal does nothing. The throttle plate motor and position sensor are ELECTRICALLY ISOLATED from the metal portion of the throttle body. This will do the same as grounding the worm gear clamp on the intake boot.

If you think you have a bad ground, why not just clean/sand the existing grounds?

Now, if you are doing this for looks, then ignore the above.

I am getting a P2100, P1290, P2101 code. Looking at the wiring diagram it seems to show something labeled as NCA (google searches suggest "No Color Available") diagram shows dotted line around the wires from the harness connected to BLK going to Ground. Can anybody explain this notation? Attached screen snap
