I've got a 93dxhatch with complete gsr swap. First of all I am using the stock gsr engine wire harness plugged into the stock civic harness at the towers. The question that i have is do I need to unplug the map sensor harness on the tb and reconnect it to the civic map sensor on the firewall, or disconect the fire wall map sensor and hook it up the tb mapsensor? I'm not showing any cels but car boggs and kicks out black smoke sometimes. Duno what to do

reconnect it to the civic map sensor on the firewall, i think?

 

no, I hooked the harness from the firewall map sensor to the sensor on the throttle body and its running great. All the vac hoses were running of the map sensor on the tb
