MAP sensors.... what's the dif from one on firewall and one on TB?
I have a 91 DA Integra (OBD0 converted to OBD1 for swap), I use the MAP on the firewall which has a vacuum line attached to the IM (the OBD0 MAP that was used when the car was dyno tuned). I have a ITR TB which has a MAP on it as well and would like to clean up my engine bay. I have extended the wires but would like to know what, if anything, will be different about usiing this MAP on the TB.
Thank you all for your help...

Checked some schematics. The map sensors are wired differently. To be able to use the ITR TB you need to rewire it.
ITR: Terminal 1 = 5 volt reference
Terminal 2 = Sensor ground
Terminal 3 = Sensor input
91: Terminal 1 = sensor input - yellow/red wire
Terminal 2 = 5 volt reference - white wire
Terminal 3 = Sensor ground - green/white wire
ITR: Terminal 1 = 5 volt reference
Terminal 2 = Sensor ground
Terminal 3 = Sensor input
91: Terminal 1 = sensor input - yellow/red wire
Terminal 2 = 5 volt reference - white wire
Terminal 3 = Sensor ground - green/white wire
