GBS Posted November 29, 2023 Report Share Posted November 29, 2023 My ifor horsebox isn’t talking to the hilux. The ifor has a 7 pin connector and the hilux a 13 pin so we have an adaptor in the middle. No lights are coming on on the ifor but the adaptor is making the hilux indicator double tick (as it always has done) until the ‘box is connected. I’ve changed the adaptor but no joy. Am I correct in thinking that if the hilux is responding to the adaptor then the fault lies with the ifor rather than the hilux? All help greatly appreciated!

billytheghillie Posted November 29, 2023 Report Share Posted November 29, 2023 have you tried putting some tape round adaptor, sometimes my caravan does that and its just a loose connection. Quote Link to comment Share on other sites More sharing options...
Cawdor118 Posted November 29, 2023 Report Share Posted November 29, 2023 How old is he Hilux and how old is the trailer? The reason I ask, is some Hilux's don't like LED lights. Are you also getting an audible alarm in the cab? Quote Link to comment Share on other sites More sharing options...

I’ll try but strange that it happens with two different adaptors. 37 minutes ago, Cawdor118 said: How old is he Hilux and how old is the trailer?

Cawdor118 Posted November 29, 2023 Report Share Posted November 29, 2023 I would go loose connection between the adapters then. Try packing it out. Quote Link to comment Share on other sites More sharing options...
London Best Posted November 30, 2023 Report Share Posted November 30, 2023 Try connecting to a different trailer. That should tell you if your trailer is at fault. My guess is that you have a bad earth somewhere, probably behind the socket on the truck. Likely not improved by the recent hard frosts, which seem to seek out bad earths.

ph5172 Posted November 30, 2023 Report Share Posted November 30, 2023 (edited) Try giving both connectors and sockets a spray with wd40 Edited November 30, 2023 by ph5172 Quote Link to comment Share on other sites More sharing options...
GBS Posted November 30, 2023 Author Report Share Posted November 30, 2023 Solved - turns out the female connectors had come loose within the car side socket. TY for all suggestions. GBS Quote Link to comment Share on other sites More sharing options...
