Message	I don't see any changes of significance compared to jzack's post to warrant a second FAQ on this: Fuse box tap Read up on the stock 95 EFI harness, a relay isn't necessary. 95 EFI harness I'd really like to see someone develop an elegant method for converting the 90-94 harnesses to the 95 configuration (ie. identify a convenient location to perform the cut & splice procedure, and a reliable method for identifying the relevant leads. See the 95 harness details above) but I haven't seen it yet. Your fuse box tap approach, and the version I linked to above, accomplish the desired task but they aren't as "clean" as it could/should be IMO. Ideally the retrofit should be every bit as transparent as it is in the 95 harness. If you can locate the common injector power lead you're halfway there, just locate the stock switched-power feed (goes to pin 45 at the ECU) and you've got it. ________________________________________ NA to TT, starting from the ground up...
