advice on extending/shortening wires

[RoccoGuy]

i'm fitting a mk2 golf wiring loom for my 16v conversion, but due to the loom entering the engine bay from opposite sides on the two cars part of my loom needs shortening and the other part need to be made longer. the problem is my wiring expertise ends at twisting wires together and wrapping it in electrical tape, and i'm hoping for some thing a little less pikey than this. can any one suggest the best way around this? i wanna try and make it as original looking as i can.

Get yourself a cheap soldering iron and some heatshrink and practise on some odd bits of wire until you get a pro looking join. Its easier than you think :)

Definately solder, anything else is not good enough.

solder and wrap with electrical tape. Or if you really want to look the biz, solder your wires and wrap with heat shrink for that factory freshness.

Whats the base Rocco? Injection or carb? If the former, you don't need the Golf wiring loom, just the 16v timing box and ignition loom. If the latter, then ignore me!
