Just pick your year and model up at the top, then in the far right box pick WIRING DIAGRAMS.
This was a great help but I have two wires I cannot work out were they go. I connect the battery and get nothing now. NO lights, nothing. I have power at the jump start plug under the bonnet, power to the starter and to the alternator. 13.3 volts ( freshly charged battery)
I have a black yellow wire that goes to the starter and another black yellow wire that has a sligtly larger eye crimp on the end. It looks to big to go to the stater as the the starter wire has a smaller crimp.
Also on the test plug there is a eye crimp coming of the side of it. Can someone tell me were that one goes please.
