Are you sure you don't want to give it a go yourself?
There's nothing intangible about rewiring any old car ...
Basically just follow the wires...
It does look daunting, but you need to take it one wire at a time and it becomes quite manageable...
It also gave me the option to make modifications ...ie
add in an ENGINE START button, handbrake warning, relays to the halogen headlights, headlight warning, hidden wiring to the engine bay...etc.
I just bought some aftermarket fuse holders and played around with lots of relays. That's about as complex as it gets...
good luck... just think of all the extra "go fast" bits you can get with all the money you save!
