Where to start?!

[Tatey]

I've finally decided to start wiring up my car after putting it of for a few months, I've got the cable tie bases ready and now just need to buy a set of ratchet crimps.

However I am having really difficulties knowing where to start, I have a premier looms wiring loom which has been a great help as it's all there with instructions, and I know what I am doing when I get to say the front loom and attaching it to the lights, fan and horn etc, but its the middle section of the loom with the fuses/instrument cluster wires that I am getting overwelmed with.

I think a good start for me will be to fix the middle section of the loom in postion, which will then allow me to work out from there and do the simple part I know how to do to build my confidence, however I am unsure where I should put everything to fix it in place. Obviously the fuse boxes will mount to the bulkhead panel, but how do people go about routing the front loom + engine loom, do they put it through a grommet in the bulk head or just bring it through the tunnel again?
