Looking good LX,
I ,ve just installed the first gen. EZ efi and found the instal went fairly smooth.I looked at the harness and laid it out to use the body plugs so there was no hole drilling.The computer mounted on the underside of the dash near the ignition switch ,routed the harness through the firewall plug for the manual trans clutch pedal rod along the firewall down the drivers side valve cover,pretty much isolated from any sources of electrical interference such as MSD . The harness is for the multi-port upgrade. Just going through the final computer learning stages. Had to upgrade the alternator and wiring to maintain constant 14 volts.The engine is a 496 stroker with a hydraulic flat tappet cam 244-256 IE @50 112 LSA 525-521 valve lift. Measured 12"-14" vacuum @ idle
