Track car wiring???
I'm on the fence and I need a push. I'm building a dedicated autocross/track car using a MSM driveline and wiring and MSPro. With the bare bones build I am doing, there is a lot of wire in that harness that will not be used.
So, do I.....
1. Buy a MSPro PnP for a MSM and take everything out of the existing harness that is not needed.
or
2. Buy a generic MSPro and start from scratch and wire the car myself.
or
3. <insert a better option>
I am technically and physically capable of either approach, but not sure which approach will be the least time consuming/frustrating.

If you want to compete with the car, there are bigger fish to fry. Leave the harness alone as much as possible, do what you need to do to get it to work.
If you want an eternal project, hack up the wiring. Or worse in some ways, do it all over from scratch.

Please note, for a Miata wiring harness, you'll need the battery harness, engine harness, and chassis harness for the car to work. If it's a stock ecu, you'll need the dash harness with the immobilizer as well.

The engine harness isn't the hard part. It's the rest of the chassis harness that is annoying.
I personally would use the 99 harness and put the msm harness in the excocet.

Remember how many clips there were when you removed the 99 harness? They all take 5 times longer when you're putting them back in for orientation, location, access, etc.
But remove every trace of wire in the 99, and install every wire you have from the msm. If you can get the cars side by side, you could probably use the msm for a rough reference. If it's a race car, strip the harness of wrapping and carefully cut out what you don't need.

i ran the holley efi for the engine, for the chassis harness i made my own. everything works but the DIY harness came out heavier then the stock one.

We rewired the lexus. It took a good 4-6 weeks with 2 of us working on it and countless hours scouring over the wiring diagrams.
If you don't have the wiring diagrams, I would pass on rewiring any car. It will be really complicated and frustrating and you won't do as good a job as factory.
Rewiring from scratch is maybe ok, but its really unnecessary. Factory wiring on the Miata is pretty good. My biggest suggestion for anyone undertaking this is to do your best to keep the factory connectors and de-pin any wires you don't need anymore. The Lexus had locks on the pins which we didn't realize until we had cut some of the wires already. This ended up being a pain since we made a few mistakes.
