Major Setback

I can't really see what is going on in that pic
could you get more up close pics of the wire that fried and the connector to the main power relay showing which wires went in which holes on the relay connector? I can compare it to mine to see if they wired it incorrectly shorting it at the relay...

didnt you get the harness that you put your own ends on?
Does the harness come all wrapped or are the wires individual?

apparently it's the black wire coming off the main relay, thats the wire which grounds the relay switch circuit... the haltech power is fused but this one probably is not.
there are 4 wires coming to the main power relay:
black: ground
grey: switched +12VDC
red: battery +Ve
yel/red: system +13.8VDC
the haltech was not installed, so assuming the connector for the relay is wired properly, the yel/red has infinite resistance (no continuity) the red would be hot, using battery as direct source...
Now since the black is the one that fried it either got some high amp current from the red or the grey, but the red, if my memory serves me correctly, goes through the haltech fuse block before going to the relay.. so that fuse would have blown.
It looks like all your juice came from your switched +12VDC source, which may or may not have been fused depending on what you used as a switched source...
It's possible the relay has an internal short... check the resistance across the terminals the grey and black wires go to. if it's 0 theres a short and it fried your wiring... but the switched source should have been fused, if it were it would have blown and the harness would be fine and dandy.
