sniper wiring RF and temp sender.

I installed a trunk battery on my 6.1 L Hemi '69 Cuda with a FAST XFI 2.0 EFI system and had a "work of art" ground installed to the bumper frame bolt. Got royally chewed out by a FAST tech support guru!!! The system did seem to work OK but apparently goes against all the instructions for installing trunk batteries with FI systems. I tore it all out and ran a welding cable to the engine!!
