For some moral support, visit this thread..... robricc's sleds, shonky's harness and tuner

For connector pinouts vistit the FAQ......... Pinouts

As for any advice,
1) Only connect the wires you will actually use
2) Use your existing harness as a reference
3) Double & Triple check the power connectors
4) Don't forget the inline fuse (see referenced thread)
5) Remember what I said before about keeping the crimp "compact" so it will enter the connector block cleanly
6) I think soldering as well as crimping is advised, but be sparing with the solder!

Not exhaustive, but a start............and don't forget to enjoy it
