Advice on towing electrics please

NickMV70 · Sep 13th, 2012, 21:44

Hi a number of months ago I changed the wiring on my towbar from a single old style pin to a new 13 pin twist in type. I have used a genuine Volvo wiring loom. The issue I have is there isn't a relay in place to enable the battery charge / fridge facility on my caravan. Does anyone please know what the part number is for the relay. Either gen Volvo or aftermarket. I have a 2002 v70 170.

Thanks

Nick

When i fitted one on mine ,02 v70, i had to connect the earth for the fridge separately.

I would check to see if that pin is earthed.

Thanks all for you input and thoughts. I'll che l to see if it is earthed but I know from memory it doesn't have a relay in position MA1 in the rear electronic module so I'm thinking I will need one of these. Will let you know how I get on tomorrow - thanks again
