Last night I was able to move forward with the install. I managed to get the factory AC harness out. I did it without messing up the harness, well except for 1 wire. It was a ground and nested under the depths of driver side wires behind the blend control box. I also removed a second relay box mounted inside the smugglers box.
I love removing items from the car that have no use
I built the bracket holding the compressor in the smugglers box. Everything went together as the updated document explained. I did add two washers on the "left cheek" top bolt as there was a gap between the spacer and the cheek that the plastic washers did not fill. Tightening it would start to bend the cheek and I did not like that. The instructions have the updated relay and how to mount it.
*EDIT - The kit came with a bag taped to the cooling fittings. Looks to be some extra M6x20mm screws. Will report back at the final if they are not used elsewhere.
The last bits to be installed. I too was plagued by the extra missing M6x20mm button head screws. The kit came with 6, but needs 8. 4 mount the top plate. 2 mount the side clamps. 2 to attach the ECU. A trip to Ace Hardware today will fix the issue. The last bolt in the pic is for mounting the red post I believe, which I am not using/was not included(RHD).
