I just picked up an '86 GT that the previous owner converted to mass air. Looks like the conversion was done half-assed. There are no electrical connectors for the O2 sensors. Also the connector for the reverse light switch is no where to be found.

Does anyone know if these are tied into the main harness that comes from under the hood, with the speedo cable? The '86 came with 2 O2's originally right?

the 86 was speed density and came with o2's and they are part of the main harness that comes out of the firewall on the passenger side. the o2 harness should plug into a black 8 pin connector right next to the mass air harness plug.

Really? I thought it was SD but still had 2 O2's. Either way it looks like I have some wiring to do.
