8)How do I wire a wideband up to the MSPNP?

By following a combination of the wideband's documentation, and the MSPNP's documentation

The wideband's documentation is going to tell you how to properly install the wideband in the car. It could care less about the EMS with one exception. You need to SHARE GROUNDS between the 'system ground' of the wideband, and the EMS. In this case we're using the stock ECU grounds through the harness, which terminate at the engine.

On the 90-93 cars this is at the rear of the head, right by the CAS, hanging off the hook/hanger on a bracket. There is a pair of wires here, and another just below this. These four wires are the ECU grounds. Ground your wideband here as well. Take care not to disturb the ECU grounds though– it may be best just to get a new nut and at it to the top of the existing exposed stud to ground the wideband.
