the 87a terminal is a "normally on" output, and when the relay is activated it switches over to the 87 terminal, and turns off the 87a. You've got it all right, but it's not necessary to use the brown wire within the headlight harness, you can just use any ground. Since I used self-tapping screws to hold the relays to the fender in the area behind the driver's side headlight, I just ran short pigtail ground wires from the relay up to the mounting screw. _____________ List Sponsor: http://www.netsville.com To remove yourself from this list, send mail to [email protected] with 'unsubscribe a2_16v' in the body of your message See us on the web at http://www.a2-16v.com Visit the 16V Homepage at http://www.gti16v.org
