just read over these posts quickly , ''maybe learn something'' . I remember back when I rewired my car w/ an E Z system , I had to tie 3 wires together on the switch to get power to start , Sean at E Z advised me to do so.
Has worked great for about 9-10 yrs . -------so far so good.
Had it all neat and good looking till I decided to go FI , and changed a few gauges , now a mess almost as bad as the factory jungle .
I did carefully remove the factory pins and reused/relocated them to match the
GM based E Z system , where I reused the chrysler plug ins. on everything , including the steering column plug in .-----fingurs still crossed.
