Jim G. --- On the 6-speed you don't have to use the adaptor, just disconnect the switch. The only reason for the adaptor is to keep the end of the wires clean in case you want to install it back in later. ( Of course the vendors don't tell you this.) I use to tie - wrap the wiring up and that's the way it was when I sold the various Corvettes I had. You don't have to procure anything for a change!
