i think he is saying the harness isnt being used because he has a turbo 400. so the harness is an "extra"! Seems pretty far away just to grab 12v."I need a wire from the transmission harness, but the harness isn't being used"
Not being smart but is it smart to touch a line that powers the fuel pump? Wont that take away voltage from my pump (I have single pump).Pretty simple: carefully tap your fuel pump positive wire. If it's going to a relay you will be fine. Be sure to use a good ground. Even when the pumps are not operating at full voltage you will have 12v at your relay with a chassis ground.
