Ok I got the red top sr20 and "new" wiring harness from jazzproparts.com, but there is one discrepancy; the throttle position sensor plugs do not match up. This wouldn't be a huge issue except the harness plug has a 3-prong connector and the TPS has a 6-prong connector. I don't know what to do. 3 wires can't just be missing. Anyone have suggestions besides buying a $300 new wiring harness?
From the sounds of it the harness you got it from a MT car and most likely the tps you have on the motor is from an auto (90% of imported det's are autos). The auto has a tps and a closed throttle sensor on the TB. The plug for the sensor is different between the two. You should just be able to swap on a mt tps and be done with it.
