I never liked the old wiring on my 200sx s13 shell..so once I got to it i ripped it all out of there, hoping to replace it with something better...right now I think it wasn't the best thing to do and I should have removed it more carefully
However I still have the old chassis harness + another harness from a spare 240sx shell, but I really don't trust that old wiring... 
so this leads me to my question - what are my chassis wiring options. Currently I'm looking at this:
1. Fix the oem old harness and place it back were it was...but just looks of the wiring scheme in the FSM scares me
2. Try using the spare harness which comes
2. Install a new universal harness - like the ones used for restorations, muscle cars, race cars etc...the wiring scheme looks much easier and seems to be a very easy install. My concern here - is 240sx specific relays and circuit limitations - the available harnesses rarely provide more than 22 circuits, whilst I'm under the impression of 240sx having much more circuits.
I don't want to overpay for the wiring stuff nor do want to make a crappy wiring job that would lead to possible electrical problems.
any other ideas, comments or suggestions?
