Hooked up the wire harness that runs from the relay board to the to various connections for the D-ironic fuel injection per Jeff Bowlsby wiring diagram, I installed a new Optima battery and turned on the ignition. Smoke started raising out of the engine compartment. shut it down and see that I melted the Black/Purple wire from the negative 1 terminal on the coil all the way up to the connector on the relay board. it appears to have taken several other wires with it. I think that this wiring harness is toast. I have two problems: (1) need to replace or fix the wiring harness and (2) what went wrong? Any ideas or suggestions on what to do next?
Just checked and found I had forgotten to connect the transmission ground strap. Could that have caused this? |

Hi Dennis, no worries, it can all be repaired good as new. The casing needs to be removed/replaced to replace any damaged circuits.
As mentioned, either the 12-pin plug was mis-indexed on the relay board or possibly the two wires to the coil were swapped. A very common issue. |
