On my V8 conversion, I need two hot in run and start +12v sources, but I'm not sure how to determine this from any of the 914 diagrams. I need to power up my PCM, and an Accusump solenoid (or maybe just one hot to activate a relay for both?).
Many thanks, Andys |

So if you are going to remove the relay board Ron's choices get reduced to no choice.
Hot when starting only - 14 pin connector Pin 1 Hot when switch is on (and start) - 14 pin connector Pin 8 Charliew has a good point though. If you use the Pin 8 for power you are going to be pulling more current through that cct than designed. I would be particularly concerned about the extra current going through the ignition switch. The factory addressed this with the main power relay. Pin 8 turns on the main power and the relay switches power directly from the battery (pin 12) You really should hook something up to replace that relay action. You'll also need a fuse to protect your equipment. Pin 12 is straight to the battery. Clarification. The ignition switch does turn off the unneccessary stuff during start. Just nothing from that post of the ignition switch makes it way back to the engine compartment. |
