O2 sensor problem!
Okay, so on my wiring harness (87 7mgte A/T) the plug for the o2 sensor has 3 wires (3 prong) and when I go to the store to replace it I get one that has 1 wire (1 prong). where can I get the o2 sensore with the 3 prong without paying a fortune?? also can I do some splicing to make it work?? what are the 3 wires for?
Also, not related to the o2 sensor, but I swapped the turbo 7m into my na body. is there any modifying i need to do electronically? like gauges, etc.. Thanks for the help! much appreciated! |

3 wire: ground, pre heat power, & ecm voltage.
Try EBay for a replacement. OEM will be in excess of $100.00. |
