If you disconnect, you will still go into limp mode. Nobody has a used one around?

There is a for-sale section on this forum and of course there is always eBay. I failed to mention that in order to get your car out of limp mode you have to have working unit plugged in whether or not you chose to premix.

Just run premix, get rid of that piece. Just plug a good omp into your loom and zip tie it out of the way to get around the limp mode problem. The only other suggestion I have so you dont have to keep the OMP in the engine bay is, you may be able to connect pin 2f on the nr TPS and pin 2a on your OMP. Basically the omp and the narrow range tps pin 2f lock into the same ic on the board, so this should work. I myself would just plug it in, premix, and zip tie the bitch out of the way. Good luck.
