In the picture it shows the 2 browns and 1 black from the flasher unit, there is 2 browns and 1 black wire coming out of the loom pretty much under the coil. That’s where it was connected, with its connected here tho the black from the coil seems a bit stretched, making more sense that the unit being connected here isn’t right

If you're connecting the black into the black coming out of the loom that is WRONG! Like others have said that is a test lead, if you connect something to it you will lose spark. Connect the black lead coming out of the flasher to a ground using another piece of wire to a bolt or screw or even the negative post on the battery.

Exactly mate, that’s where it WAS connected, and caused loss of spark, from my original reply this was where it was fitted and clearly mistakenly connected into the loom, I guess it’s an easy mistake as it has the same colour and number of wires coming out of it,

That doesn't look like the correct flasher relay, and where the wires go in, it looks a bit bodged.

If the relay matches the mount, then it is 12v one from a 1974 DT125 (see the 444 printed on the mount).

The original relay had just the two wires and a link to photos of this item is attached.

In theory, most 6v relays should work ok on the bike, so long as the wattage of the bulbs is in the same ballpark as the wattage printed on the end of the relay. Modern two pin relays will work fine as well.

Yes until i read the last bit i was going to say my HT1 has two wires ,one brown and the other brown and white from the flasher relay and the indicators work on my year later model . Kev, i'm not joking, don't take what you get from an American or Canadian bikes as correct if you're in the UK. The different people who have owned your bike and the places they lived are more varied than you can imagine. So was their access to information, no computers or smart tech phones. I also find that " anything can be made to work" mentality is well and truly rule of thumb with bikes from the farming communities as lots of states in the USA are.
My first vintage Yamaha enduro had a genuine bolt with a hole drilled in it with a nail pushed through and two cigarette butts holding the left head lamp bracket to the head lamp bowl to keep it in place. That was a UK bike too. A bike who's owner lived not to far from a dealer or hardware shop as any place in the UK.
What i'm saying is, Knowledge is power. Use CMSNL, the Tech page and here too and usually you won't go wrong.

Edit : Clymer manuals are a great discovery by the way. Much better than Hains in some ways.
