I've swapped multiple relays to the IGN1 slot with the same outcome....I have since swapped out the underhood fuse block, ignition switch, and the off chance the EBCM...all having the same issue
now, i decided to give my ECT2000 a shot at this...and sure enough it began to beep at me a little below the fuse box, so i disconnected all connections to the junction block (not fuses and relays, but the 7mm bolt hold downs ) beeping stopped. plugged in the harness that controls IGN1 relay and the beeping returned...i have a short to ground in that harness...traced the "beep" to under the dash...unfortunately for me the harness disappears...i guess i need a wiring harness diagram or remove the dashboard itself...and that is a giant FML
