More EFII install
The stock harness ground was too short so I used butt splices and routed the grounds inside the conduit along with the manifold pressure hose.
The kit comes with this...
I used this instead with a .063 doubler, it is steel 1 3/4 inch inside diameter the connectors fit through and less than $2 at HD.
The black line on the right is for manifold pressure and joins the manifold block.
The other wires follow the engine mount. I still need to fire sleeve/seal between the steel fitting and the conduit.
The right side of the engine where the coil and flywheel pickup snap in.
The connectors on the ECU, I still have to mount the manifold pressure sensor. There is +\- for the ECU and a+ for each coil output. I'm just using a single EFII but the wiring harness and ECU is set up to run dual ignition except for the extra coil and wires.
I'm running the power to the ECU through a switch, you could alternatively switch the power on the coil to enable/disable the EFII. A double pole switch could also be used to disable both ECU and Coil power simultaneously.
Manifold pressure sensor mounted.
