The harness inserted into the Printed Circuit can be installed two ways it appears. Their is a raised leg on one side of harness clip corresponding with the larger pin numbers. Do the larger numbers install on the right or left? Just curious. I believe the stiff loom makes it obvious but who wants to do this twice.
There is only one way to plug the dash cluster connector into the dash cluster. I’ve not paid attention to which side the key is on; as I have documentation for which pin goes into which slot. Sorry…
Yes, only one way…exterior insert tabs are two different sizes.
