checking taillight operation?
just purchased a '05 taillight off ebay. i plan on sending it in to mccoy to have the integrated taillight kit placed on it.
i want to make sure it is in working order before i send it out.
my questions is, can i disconnect my current stock unit's plug and just plug it into the recently acquired unit to see if it works?
i don't need to 'ground' it in any way do i?
