In preparation for mounting the body, I have now loomed the 6 wires from the transmission pigtails installed a few weeks ago, contained in split 6.5mm convoluted sleeve with branches bound by electrical loom tape. This has the advantage of extending the wiring to the engine bay making access theoretically much easier than when the body is on.
Vehicle Speed Sensor = Yellow & Purple
Reversing light = Green & Slate
Reverse Solenoid = Pink & Green
These are then extended and wrapped in spiral convolutd sleeving and presented to the engine bay for further integration into the main loom.
