I have just committed a most heinous sin - no, not like the parrot we call Onan. I have just used a Scotchlock; even despite the most recent exchange.
My defence, and the basis for request of absolution, is that it was only to power the radio. I've been suffering for a long time for it being powered off the ignition circuit, so it goes off with the engine. But I finally got a round tuit and connected it to the white and pink wire off the first position of the ignition switch. But I was not going near the connector, So I chose to wire it in by committing the aforementioned grievous sin.
So I petition for absolution or at least a moderately light penance - please not crawling on hand and foot to the birthplace of the sainted George Herbert Skinner (who had an interesting CV); it's in Northamptonshire!
You are already doing your penance, this bit of bodgery will nag at the back of your mind till you fix it properly!
"It's only the .......... " is a slippery slope! I don't even use the cursed things when wiring a towbar and several of them are included in the connection kit!
But it's your car, you can (and probably WILL) do what you want with it! So, in nomine patri, et filii, et spiritu sancti, Amen!
