Greetings
I have a 94 Miata MX5. I recently removed a very old 3rd party alarm system and now my car won't start. I've narrowed this down to a mystery 4-way plug in my trunk (Red w/ Blk Stripe, Light green, Dark Blue w wt stripe) . If I jump power to the Blk w white stripe connector in the plug it will energize control panel and instruments, It will start but wont turn off with key.
The plug doesn't seem to have a home.
Any help would be greatly appreciated.

not oem, most of the non stock alarm systems are wired into the harness around the steering column i dont recall where exactly but start looking for split wiring. heres a whole car (split into the various pars) wiring diagram. good luck.

I figured out the mystery plug is for auto antenna. I will look around steering column.
