no problem.
Just connect to the normal OP switch under the left cylinder head.
Just leave the one by the 2.1 crank pulley disconnected .

( or screw in a proper plug instead. )

AND ...just reminded me..
you want to put the 1.9 crank pulley on the 2.1 ..
as it has the correct timing marks for the  1.9 distributor and fuel system.
