i put a 5.7 Hemi and 545rfe trans from an 05 1500 2 wheel drive into my 1970 charger. when i first did this i hooked the stock wiring harness to the car to all the the necessary plugs and after some trouble shooting i finally got it to crank. when i hit it with fuel pressure i was trying to start it. when i started cranking it didn't seem to fire and after a few seconds the whole system lost all of its power. battery checked out good and it was getting late so i gave in for the night. i then found a wiring schematic by Boden and decided to try it out. when i finished the modifications to the harness i hooked everything up except for the stock under hood fuse box. when i hooked it to the batter i had nothing. i then unhooked the battery and just plugged all of the plugs into the fuse panel, i did not however hook the main batter cable to the fuse box. and now when when i hooked up the battery the throttle butterfly twitched for a second or 2 then stopped. still however it would not crank over and nothing had power. i then hooked up the main battery cable to the fuse panel and now when i hooked the battery up the throttle blade would still twitch and stop but since the fuse panel was hooked to the batter a headlight that was still in the dodge harness turned on and stayed on for 1-2 seconds then it shut off, around the same time as the butterfly stopped moving, and that's when the power loss happens. i then tried to unhook then hook up the battery and crank as soon as i hooked it up but the engine still would not crank. any help would be greatly appreciated thank you.
