This is in your 2002 i assume? does it work the same for the idi's? i know i dont have that many connectors under the hood in the area you refer to. will it still work by just grounding the violet/yellow wire and just deal with the OD light blinking? i could prob make the box after a while but would like to be able to lock up the TC now. it would also take me awhile to build the box but i will prob do it. just in case the OD light blinks for a real reason.
i tried finding the switch you used but the part number did not show up on radioshacks website. is it just any two pole switch, say from autozone or napa? everything else i found fine though.
did you put any resistors in for your led?
