A long task to check the wiring...agh! Not the greatest of solderers but the joints did look pretty secure before putting heat shrinking insulation over them. Will take the IPK out first to check the plug and cavity used. One thing I did notice when starting up the cruise light on the IPK flickered briefly before going out. The cruise interface was bought second hand and came with connector and part of the loom, I can only assume it works!!! I used the yellow/black & yellow/brown wires coiled together above and to the left of the fuse box just before they go through the bulkhead. I used fuse piggy back (?), instead of scotch locks for the connections to fuse 41 & 4, they plug in where the fuse goes, takes the original fuse and provides a 2nd fused circuit. Other than that more or less followed the instructions. I've read elsewhere the car might not recognise the cc interface straight away? Thoughts on that one or clutching at straws!!!
