[QUOTE="olgreydog7, post: 10496367, member: 65150"] Short story, 99 Cobra, stock harness and ECU, tuned with SCT, big bore stroker with a Sullivan intake and the EGR deleted. I tapped the spacer for a vacuum port and I'm pretty sure it is leaking. There is a portion of the main harness that has boots on it that plug into the sensor on the end of the fuel rail, a couple that plug into the cylindrical thing that bolted to the side of the stock manifold, and two that had direct ports to the intake manifold. I know I need the sensor at the fuel rail since I am still running a returnless setup, but what about the other boots? What do they control? Can I turn them off and delete them? [/QUOTE]
