...you don't know(or maybe you do) how many how to relay sites until I tried yours. It's amazing how straight forward conversation really works. Thank you very much. Ed

Greetings from Scotland, very straightforward and easy to follow! many thanks! that helped me with some work I'm doing on my old TR6 car, here we call those yellow connectors "Spade Connectors", I'm sure they might get called something else in other parts of the world.

Great video Sir 👍 I know very little about automotive wiring but I thought I knew enough to extend the ground wire from the relay 6 inches using the same gage wire but after doing this seemingly simple thing the lights don't work yet the red and green lights on the switch work and fuse is still good so I have no clue what happened or how to fix it ?

[marianmarian]

Very good explanation... My question is ... Can i remove the switch and have a direct power to the lights? How i can do this? Just remove the wire from 86?

Wish I seen this two months ago when I wired my Rigid D2’s up. Couldn’t use the Air on Board switch because the original D2 Pro’s didn’t come with a relay.

[avelinovelez]

Thank you very much great video very informative 👍

[woadscout]

Thank you for such a great explanation video!

How do you know which number of fuse to use? 10, 15, 20, etc?

[andrewbennett]

So I could wire this sucker into my fuse box for my starter, with a killswitch in series along the control wire, yes ?
