GM 21 circuit universal harness

The thing is, even the "other" universal harnesses are not "Mopar compliant". I believe painless ships them, example, with GM turn signal connectors, and a mating shell. You are suppposed to whack off your Mopar TS connector on the switch side, and add the GM style connector so it will mate. I've never heard of anyone being able to source parts for that original column ignition switch connector, so you might as well "go GM"

My E Z kit was GM too , I changed everything over to my orig mopar ends , sockets and signal light/column plug ins . Just clean up or replace the dirty/bad mopar stuff to start with.
The pins will come out of the lower column plug for refitment , to keep it all mopar ------------- I did have to replace one rear tail light socket , but they can be found .
