510revisited Posted December 8, 2019 Report Share Posted December 8, 2019 (edited) I'm at the end of my efi install. Holley sniper 2300 efi. Just wiring now. Everything else is done. I'm having a hard time locating a 12v cranking source. Instructions say 12v while cranking and run position.. need help. 69 datsun 510 2 door. Stock harness. I've tried every wire that comes out of the key ignition plug. None of them stay at 12v while cranking. They all jump down to 9 ish. Btw, instructions say not to connect to starter solenoid or ign coil. Edited December 8, 2019 by 510revisited Quote Link to comment
