I was wondering if anyone here has a MagnaVolt on a 04 Silverado? I installed one on my 6.0 with a Whipple put i don't think it working(fuel pressure still drops to 35psi). I have the instructions for the 05-06 SSR from the Magnuson website but not sure if the wires are the same on the silverado since its a ls1 not ls2 like the ssr. I basically just need to know on a couple of wires if they are the right ones or not.

Any help would be great.

Thanks

 

On the White Wire (RPM signal): Put a small pin through the wire and test it for voltage that goes up and down with rpm's. It is in the big connector at the firewall.

On the Yellow Wire (Fuel Pump Power): Check the underhood fuse box for fuel pump fuse. Then unplug the large connector under that portion of the fuse panel. Locate the Yellow (Fuel Pump Power) wire and tap into it per the instructions.
