Indicators beeping but no trailer is hooked up

Hi, I just did the wiper linkage repair today, and I don't think it's anything to do with what I've done today, but I noticed when I was arming and dis arming the alarm when every the indicators flashed the car would beep like it would when there's a trailer hooked up, now I've narrowed it down that it only happens when indicating right, this problem wasn't there before I did the wiper fix but I think it's just a coincidence. Anyone got any ideas how I can find the fault? As its driving me nuts when I'm signalling right

oh I forgot to say the previous owner has cut the socket off, I've removed all the tape and had a look at the wires and it's all clean and no wires are touching each other

I got it sorted, I found the smart relay hidden in the rear quarter, give it a tap and it seemsto have sorted it. if it happens again ill just remove it. Thanks for your help
