Message	If you review the auto-FAQ on the 95 harness, you'll note that Pin 58 is designed to receive constant power. This is true for both the 90-94 harness AND the 95 harness, and as best I can tell from the wiring diagrams this is the ONLY constant power source for the ECU. The white wire w/ black stripe that is shown severed and connected to the switched relay in this writeup is the feed for the injectors AND for Pin 58 of the ECU. As far as the ECU is concerned, changing this to a switched circuit is equivalent to disconnecting the battery and you are resetting the ECU every time you turn the key on and off! Not wise. The desired result is to convert the injectors to switched power, NOT the entire circuit. ________________________________________ NA to TT, starting from the ground up...
