Ms3x357 wiring for 1990 Miata with diyBOB?
I looking to wire a Ms3x3.57-c With 1.3.4 Can Enabled firmware with the DIYbob PNP. Also Have the have a innovate lc-2 and the Gm- AIT.
Car 1990 Miata 100% stock low mile (80,000miles) Runs great has no starting no running problems, Looking to get the car running on the MS3 1st and maybe boosted it this winter. I have searched lots on how to wire it found some pinout pics and such just not sure on if i need to add jumper in the box to even run the expansion board yet or just wait till the car is Boosted to run the spark, fuel and boost of it.

Why not run the 1.4.1 firmware?
Do you mean it doesn't have starting or running problems, since you said it runs great? If it does have issues, I would solve them before going Megasquirt, or at least narrow them down to an ECU issue. If it runs poorly, you'll be chasing issues when you're trying to start on a new ECU.
http://westfieldmx5.devocht.com/ Find the 90-97 MS3 build manual in here. Follow the guide on how to build the board. Just ignore the parts about mounting the stock ECU connector in the case. Then use the pinouts to make your DIYBOB.
Don't wait until the car is boosted to sort this out. Get it running well on MS3+MS3x first.
