1992 240 gl sedan m47 transmition. how to disconect backup switch?

There are two blue wires that blow fuse #5 when the car is put into gear. The fuse does not blow when the wires are disconnected but then i have no turn signals. I think the backup switch is blowing it but i don't know where it is and I don't know how to disconnect it.

The reverse light switch is located on the transmission. Its screwed into the left side of the shift cover.

The switch passes power directly to the reverse lights and does not have a relay.

The 2 wires from the switch are routed through the shifter hole, under the carpet and should go to a connector behind the right side of the center console.

Doesn’t that wiring have a habit of chafing against the trans or body metal and grounding out?

Yes.



Wire replacement is a bother. Use the correct wire. Hope you can re-use the two bullet style connectors, or get new. Get tough wire covered in high temp insulation meant for under car use (heat, road grime, dribbly oil coating the wire). Maybe place in a sheath and seal the sheath to the wire at least at the under car end to limit crud intrusion.

Have to lower the transmission quite a bit to gain access. The exhaust gets in the way a bit.

On my 1990 240 DL (li'l red) Wagon, I installed an unused 240 power mast aerial switch. Disconnected the wire harness from the connector where the blue wires route through the gear shift lever hole. Find the connector under the carpet near your ankle in the US left hand drive driver foot foot well. The two blue wires not under the car was fine. Connected two wires to the blue wires and routed with quick connect spade terms to secure at the 240 power mast aerial switch.

As the 240 power mast aerial switch does not light when on, I tend to forget to turn it off (sometimes on). Oop!

Not my dash. Same 240 power mast aerial switch I use for reverse lights between red EXHAUST TEMP warning light and green REAR DEMIST toggle switch.

On the plus side, with the 240 power mast aerial switch switched on and the reverse lights illuminated behind the 1990 240 DL (li'l red) Wagon, makes for useful light when when needed.

Hope that hepkats (halps).

Questions?
