mas28O Posted August 2, 2003 Share Posted August 2, 2003 I need to find out if the Lt1 computer uses ground to switch the relay or B+. I have the wires from a10 and a11. I want to have the car ready for HOT Auugust nights in Reno. Thanks Mike Quote Link to comment Share on other sites More sharing options...
