Mark69 Posted March 16, 2021 Report Share Posted March 16, 2021 (edited) This evening I wired up the overdrive using new loom and overdrive harness , connected the yellow purple from relay to overdrive solenoid and yellow green to switch and the black from column switch to gearbox switch . This is were I got confused , on the main loom the spur that comes from the relay splits into two ,yellow purple and a yellow the other yellow green and another yellow . It’s the two yellows that confuses me I have no idea where they connect. With the ignition turned on the solenoid operates in 2nd 3rd and 4th. Not road tested.

Mike C Posted March 16, 2021 Report Share Posted March 16, 2021 Yellow/purple goes from the relay to the solenoid, yellow/green from the relay to the column switch, yellow from the column switch to the gear inhibitor switches and across from one I/S to the other. Make sure the bullet connectors are tight , loose connectors caused a few intermittent O/D drop outs on mine until I tracked them down. Quote Link to post Share on other sites
Mark69 Posted March 16, 2021 Author Report Share Posted March 16, 2021 That’s how I have wired it Mike , it’s the two extra yellow wires that I have and can’t find them on any wiring diagram. Quote Link to post Share on other sites
RogerH Posted March 16, 2021 Report Share Posted March 16, 2021 Hi Mark, could the extra yellow be for an 'A' type OD with the extra inhibit switch Roger Quote Link to post Share on other sites
Mike C Posted March 16, 2021 Report Share Posted March 16, 2021 (edited) Sorry, forgot to mention I have an 'A" type O/D with 2 inhibitor switches. Are you sure you have the original wiring? I couldn't get the yellow with stripes when I rewired mine and most of the wires are straight yellow- for trouble shooting I just follow the wires where I can see them and sort any concealed wires out with a multimeter set on ohms.

Next YP goes to to the Y on the gearbox switches. Hope this makes sense. I MAY BE WRONG ON THIS!!! Quote Link to post Share on other sites
