rear light/indicator questions

Firstly, on the rear lights, there's 6 spade connectors on the reverse of the bulb holder, what are they for and why is there a wire connecting one of them to the same one on the other light? Also, which one(s) should it be on, if any?

Secondly, my indicators seem a little fast, I presume my car had side repeaters and now doesn't  :dontknow: is there any way I can make them flash slightly slower (all the bulbs are working, so it's not that)

Ta very much.

First question tow bar lights .Strap will be fog light only required on one side , UK drivers !

Second question Change the flasher relay for a Hella one , some cheap one's flash fast , some old Hella one's do as well its just pot luck i tried 2 before i was happy , oh and make sure all the ind bulbs are correctly watted at 21.

Hope this helps

I moved that random wire around earlier and without it on, only one sidelight works, so it needs to stay on the sidelight spade on my car apparently

Which foglight should work? driver's? if so, I'll have to get another wire and connect the 2 together.

I had a feeling they'd be for trailer lights.

Thanks for the info about the relay
