To elaborate on the need to cut the turn signal wires, The oem plugs will slip though the oem turn signal's hollow bolt's nut. The Kellermann turn signals will not allow the oem connectors to pass through the Kellermann turn signals hollow bolts nuts.
I soldered on the oem connectors to the Kellermann turn signals and found out the hard way that those nuts are too small to allow the connectors through! Not on this install but when I fist installed them a ways back.
In summary, aftermarket turn signals may allow for the eom connectors to pass through, Kellermann turn signals, for sure, do not.
